Front Med (Lausanne) 2025; 12:1582008. [PMID: 40443510 PMCID: PMC12119253 DOI: 10.3389/fmed.2025.1582008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2025] [Accepted: 04/29/2025] [Indexed: 06/02/2025] Open
Abstract
Background Hemoptysis is a life-threatening manifestation frequently observed in patients with cystic bronchiectasis (CB), a radiologically defined subtype of bronchiectasis. Bronchial artery embolization (BAE) is widely employed as an effective interventional therapy for controlling hemoptysis. Despite its clinical utility, the risk of recurrence remains high, particularly in patients with CB. Currently, no reliable predictive model specifically targeting CB-related hemoptysis recurrence following BAE has been established, highlighting the need for a tailored prognostic tool in this population. Objective This study aimed to develop and validate a model to predict the recurrence of hemoptysis in CB patients following BAE, enabling individualized clinical management and prevention strategies. Methods A retrospective study was conducted on 111 CB patients who underwent BAE between January 2015 and June 2020. Clinical, radiological, and laboratory data were collected for analysis. Least absolute shrinkage and selection operator (LASSO) regression was applied to identify relevant predictive variables, followed by multivariable Cox proportional hazards regression to determine independent prognostic factors. Based on these predictors, a nomogram was constructed. Its performance was assessed using the concordance index (C-index), receiver operating characteristic (ROC) curves, area under the curve (AUC), calibration plots, and decision curve analysis (DCA). Results Five independent predictors were identified: history of hemoptysis (HR = 3.42, 95% CI: 1.64-7.12, p = 0.001), diabetes (HR = 15.0, 95% CI: 4.69-48.1, p < 0.001), pleural thickening (HR = 3.78, 95% CI: 1.07-13.4, p = 0.039), prolonged hospitalization (HR = 1.99, 95% CI: 1.08-3.67, p = 0.028), and positive sputum culture (HR = 2.29, 95% CI: 1.26-4.19, p = 0.007). The nomogram showed good discriminatory ability, with AUCs of 0.778, 0.797, and 0.829 at 1-, 2-, and 3-year follow-ups, respectively. The integrated Brier score was 0.147, reflecting good overall accuracy. Time-dependent AUC and C-index curves further confirmed the model's prognostic robustness. Calibration plots demonstrated close agreement between predicted and observed recurrence, and decision curve analysis indicated favorable clinical utility. Recurrence-free time was significantly shorter in the high-risk group (p < 0.0001). Conclusion The nomogram is a reliable tool for predicting hemoptysis recurrence in CB patients after BAE. It facilitates early identification of high-risk patients, enabling timely, targeted interventions and improved outcomes.

Bronchial artery embolization for the treatment of hemoptysis: permanent versus temporary embolic materials, a single center study. CVIR Endovasc 2025; 8:40. [PMID: 40335822 PMCID: PMC12058560 DOI: 10.1186/s42155-025-00554-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2025] [Accepted: 04/16/2025] [Indexed: 05/09/2025] Open
Abstract
BACKGROUND Bronchial artery embolization (BAE) is a common interventional radiology technique used to control significant bleeding from the bronchial circulation, especially in cases of severe hemoptysis or pulmonary hemorrhage. The choice of embolizing agents plays a key role in the success, recurrence of bleeding, and safety of the procedure. However, there is no consensus on the ideal embolizing agent. This study compares the efficacy, safety, and long-term outcomes of using permanent versus temporary embolizing agents in BAE. METHODS This retrospective cohort study included patients who underwent BAE at our institution from July 2006 to May 2024. Inclusion criteria encompassed patients with hemoptysis requiring intervention, complete clinical and radiological data, and BAE with either permanent (e.g., coils, PVA particles) or temporary (e.g., gelatin sponge) embolic materials. Exclusion criteria included non-bronchial causes of hemoptysis, BAE as part of a lung transplant protocol, or use of combined embolic materials. Primary outcomes included early clinical success (cessation of bleeding during the procedure and no recurrence within a week) and late clinical success (no bleeding recurrence within 6 months). Secondary outcomes focused on procedural complications, such as pneumonia, lung infarction, or bronchial ischemia. RESULTS This retrospective study included a total of ninety-four procedures performed in eighty-five patients (56 males, 29 females; mean age 59; age range 8-92 years) who were admitted for BAE between July 2006 and May 2024. Permanent embolic materials were used in 59 procedures (64%), in most cases were used particles and glue (39% and 21%, respectively), while temporary embolizing materials (gelatin sponge) were used in 35 procedures (37%). Statistical analysis showed a superiority in terms of clinical outcomes in favor of permanent embolic materials (p-value 0,047). CONCLUSIONS BAE is a safe procedure for control of hemoptysis of varying etiologies and possesses high rates of immediate clinical success with few complications. In terms of embolic materials, a superiority in term of late clinical success and lower hemorrhage recurrency rate with permanent materials were clearly observed in our population, with a similar safety profile. Further studies are needed to confirm our findings and strengthen evidence.

Abstract
Mediastinal hematoma due to transradial PCI is rare. We reported a case of chest tightness, dyspnea, progressive neck swelling after transradial PCI. Clinical examinations such as chest computer tomography were completed and identified as mediastinal hematoma caused by a rupture of the subclavian artery branch and occlude the artery under digital subtraction angiography guidance, the artery was considered to be a collateral vessel of non-bronchial arterial circulation. This case highlights the necessity of exercising extreme caution when utilizing hydrophilic-coated curved-tip guidewires during the advancement process in peripheral vascular procedures. Mediastinal hematoma is a life-threatening complication and progresses rapidly, we need timely identification and diagnosis based on symptoms and appropriate clinical examination, interventional embolization therapy is critical for patients with poor response of conservative treatment.

Preliminary investigation of the significance of cavitary lesions in recurrent hemoptysis following bronchial artery embolization for nontuberculous mycobacterial pulmonary disease. Respir Investig 2024; 62:1227-1232. [PMID: 39522366 DOI: 10.1016/j.resinv.2024.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2024] [Revised: 10/31/2024] [Accepted: 11/02/2024] [Indexed: 11/16/2024]
Abstract
BACKGROUND Nontuberculous mycobacterial pulmonary disease (NTM-PD) varies widely in clinical presentation, and some patients experience hemoptysis. Bronchial artery embolization (BAE) is a treatment option for hemoptysis caused by NTM-PD. However, the association between post-BAE rebleeding risk and the presence of cavitary lesions has not been fully elucidated. METHODS A retrospective observational study was conducted on patients with NTM-PD who had undergone BAE at our institution. Patients were classified into Cavitary and Non-cavitary groups, and baseline characteristics and clinical outcomes were compared. RESULTS Among the 155 BAE cases between 2013 and 2023, 18 were included in the analysis, and four experienced rebleeding. The Cavitary group tended to have a higher rebleeding rate 24 months after BAE (37.5% vs. 10.0%, p = 0.27). Furthermore, the Cavitary group showed a significantly higher number of non-bronchial arteries involved (median number: 1.5 vs. 0.0, p = 0.02), a higher proportion of patients with a prior antibiotic treatment history (100% vs. 20%, p = 0.001), and longer duration from diagnosis to BAE (median year: 9.0 vs. 0.6, p = 0.02). The Kaplan-Meier curves showed a tendency for shorter rebleeding-free survival in the Cavitary group (p = 0.10). CONCLUSIONS Cavitary lesions in patients with NTM-PD may predict higher rebleeding rates after BAE. Further research with larger cohorts is needed to better understand rebleeding risk factors in BAE for NTM-PD.

[PMID: 38138876 PMCID: PMC10744930 DOI: 10.3390/jpm13121649] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 11/21/2023] [Accepted: 11/23/2023] [Indexed: 12/24/2023] Open
Abstract
INTRODUCTION Hemoptysis is one of the most common symptoms of respiratory system diseases. Common causes include bronchiectasis, tumors, tuberculosis, aspergilloma, and cystic fibrosis. The severity of hemoptysis varies from mild to moderate to massive hemoptysis and can easily lead to hemodynamic instability and death from suffocation or shock. Nevertheless, the most threatening hemoptysis that is presented to the emergency department and requires hospitalization is the massive one. In these cases, today, the most common way to manage hemoptysis is bronchial artery embolization (BAE). METHODS A systematic literature search was conducted in PubMed and Scopus from January 2017 (with the aim of selecting the newest possible reports in the literature) until May 2023 for studies reporting massive hemoptysis. All studies that included technical and clinical success rates of hemoptysis management, as well as rebleeding and mortality rates, were included. A proportional meta-analysis was conducted using a random-effects model. RESULTS Of the 30 studies included in this systematic review, 26 used bronchial artery embolization as a means of treating hemoptysis, with very high levels of both technical and clinical success (greater than 73.7% and 84.2%, respectively). However, in cases where it was not possible to use bronchial artery embolization, alternative methods were used, such as dual-vessel intervention (80% technical success rate and 66.7% clinical success rate), customized endobronchial silicone blockers (92.3% technical success rate and 92.3% clinical success rate), antifibrinolytic agents (50% clinical success rate), and percutaneous transthoracic embolization (93.1% technical success rate and 88.9% clinical success rate), which all had high success rates apart from antifibrinolytic agents. Of the 2467 patients included in these studies, 341 experienced rebleeding during the follow-up period, while 354 other complications occurred, including chest discomfort, fever, dysphagia, and paresis. A total of 89 patients died after an episode of massive hemoptysis or during the follow-up period. The results of the meta-analysis showed a pooled technical success of bronchial artery embolization equal to 97.22% and a pooled clinical success equal to 92.46%. The pooled recurrence was calculated to be 21.46%, while the mortality was 3.5%. These results confirm the ability of bronchial artery embolization in the treatment of massive hemoptysis but also emphasize the high rate of recurrence following the intervention, as well as the risk of death. CONCLUSION In conclusion, massive hemoptysis can be treated with great clinical and technical success using bronchial artery embolization, reducing mortality. Mortality has now been reduced to a small percentage of cases.

Does the presence of systemic artery-pulmonary circulation shunt during bronchial arterial embolization increase the recurrence of noncancer-related hemoptysis? A retrospective cohort study. Respir Res 2023; 24:119. [PMID: 37131263 PMCID: PMC10152774 DOI: 10.1186/s12931-023-02427-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Accepted: 04/19/2023] [Indexed: 05/04/2023] Open
Abstract
BACKGROUND The presence of systemic artery-pulmonary circulation shunt (SPS) during the bronchial arterial embolization (BAE) procedure, has been inferred to be a potential risk factor for recurrence. The aim of this study is to reveal the impact of SPS on the recurrence of noncancer-related hemoptysis after BAE. METHODS In this study, 134 patients with SPS (SPS-present group) and 192 patients without SPS (SPS-absent group) who underwent BAE for noncancer-related hemoptysis from January 2015 to December 2020 were compared. Four different Cox proportional hazards regression models were used to clarify the impact of SPSs on hemoptysis recurrence after BAE. RESULTS During the median follow-up time of 39.8 months, recurrence occurred in 75 (23.0%) patients, including 51 (38.1%) in the SPS-present group and 24 (12.5%) in the SPS-absent group. The 1-month, 1-year, 2-year, 3-year and 5-year hemoptysis-free survival rates in the SPS-present and SPS-absent groups were 91.8%, 79.7%, 70.6%, 62.3%, and 52.6% and 97.9%, 94.7%, 89.0%, 87.1%, and 82.3%, respectively (P < 0.001). The adjusted hazard ratios of SPSs in the four models were 3.37 [95% confidence intervals (CI), 2.07-5.47, P < 0.001 in model 1], 1.96 (95% CI, 1.11-3.49, P = 0.021 in model 2), 2.29 (95% CI, 1.34-3.92, P = 0.002 in model 3), and 2.39 (95% CI, 1.44-3.97, P = 0.001 in model 4). CONCLUSIONS The presence of SPS during BAE increases the recurrence probability of noncancer-related hemoptysis after BAE.

[PMID: 36658375 DOI: 10.1007/s00270-023-03361-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 01/04/2023] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To compare the safety and effectiveness between bronchial artery embolisation (BAE) and conservative treatment for bronchiectasis-related nonmassive haemoptysis patients. MATERIALS AND METHODS From January 2015 to December 2020, consecutive bronchiectasis-related nonmassive haemoptysis patients who underwent either BAE (n = 98) or conservative treatment (n = 118) were included. Treatment-related complications, length of hospital stays, clinical success rate, patient satisfaction, and recurrence-free survival rates were compared between groups. Prognostic factors related to recurrence were also analysed. RESULTS During a median follow-up time of 44.8 months (range, 2.4-83.6 months), 34 and 66 patients in the BAE and conservative treatment groups suffered relapse. The 1-year, 2-year, 3-year and 5-year haemoptysis-free survival rates in the BAE and conservative treatment groups were 79.2%, 68.1%, 62.8%, and 57.6% and 64.0%, 52.8%, 44.1%, and 37.0%, respectively (P = 0.007). The minor complication rate after BAE was higher than that after conservative treatment (23/98 vs. 12/118, P = 0.008). BAE was associated with shorter hospital stays (5.0 vs. 7.0 days, P = 0.042) and higher patient satisfaction (88.8% vs. 74.6%, P = 0.008) than those for conservative treatment and with comparable clinical success rates (95.9% vs. 91.5%, P = 0.192). Treatment type, haemoptysis duration, and bronchiectasis severity were independently significant predictors of recurrence for these patients. CONCLUSIONS BAE could be another option for bronchiectasis-related nonmassive haemoptysis patients. In the patients with longer duration and more severe bronchiectasis, BAE still appeared to have better long-term haemoptysis control than conservative therapy.

Prevalence of non-bronchial systemic culprit arteries in patients with hemoptysis with bronchiectasis and chronic pulmonary infection who underwent de novo bronchial artery embolization. Eur Radiol 2022; 33:4198-4204. [PMID: 36472693 DOI: 10.1007/s00330-022-09310-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 10/01/2022] [Accepted: 11/21/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVES To identify the prevalence of non-bronchial systemic culprit arteries and their relationship to bleeding lobes in patients with hemoptysis with bronchiectasis and chronic pulmonary infection who underwent de novo bronchial artery embolization (BAE). METHODS Data of 83 consecutive patients with bronchiectasis and chronic pulmonary infection (non-tuberculous mycobacteriosis, aspergillosis, and tuberculosis) who underwent de novo BAE between January 2019 and December 2020 were retrospectively reviewed. The prevalence of culprit arteries was investigated. RESULTS Fifty-five patients (66%) had 172 non-bronchial systemic culprit arteries. The bleeding lobes were the right upper, right middle, right lower, left upper, and left lower lobes in 14 (17%), 20 (24%), 7 (8%), 31 (37%), and 11 (13%) patients, respectively. The internal thoracic (49%; n = 41), intercostal (28%; n = 23), and inferior phrenic (28%; n = 23) arteries were the top three non-bronchial systemic culprit arteries, which were involved in all five types of bleeding lobes. The costocervical trunk and thoracoacromial and lateral thoracic arteries were predominant in patients with upper lobe bleeding. Ligament arteries were predominant in patients with left lower lobe bleeding. CONCLUSIONS These findings will better ensure the identification of non-bronchial systemic culprit arteries in patients with hemoptysis with bronchiectasis and chronic pulmonary infection. All systemic arteries, especially those which are adjacent to the lung lesions, should be evaluated carefully using MDCT; the internal thoracic, intercostal, and inferior phrenic arteries should be proactively assessed using angiography. KEY POINTS • Non-bronchial systemic culprit arteries were identified in 66% of patients with hemoptysis with bronchiectasis and chronic pulmonary infection who underwent de novo bronchial artery embolization. • The internal thoracic (49%), intercostal (28%), and inferior phrenic (28%) arteries were the top three arteries, which were involved in all five types of bleeding lobes. • The costocervical trunk and thoracoacromial and lateral thoracic arteries were prominent in patients with upper lobe bleeding, and the ligament artery was prominent in patients with left lower lobe bleeding.

Abstract
Background Massive hemoptysis is a rare but potentially life-threatening condition of patients with cystic fibrosis (CF) and advanced pulmonary disease. Hypertrophied bronchial arteries are understood to cause massive hemoptysis when rupturing. Risk factors to predict massive hemoptysis are scarce and bronchial artery diameters are not part of any scoring system in follow-up of patients with CF. Aim of this study was to correlate bronchial artery diameter with massive hemoptysis in CF. Methods Bronchial artery and non-bronchial systemic artery diameters were measured in contrast enhanced computed tomography (CT) scans in patients with massive hemoptysis and compared to patients with end-stage CF and no history of hemoptysis. Demographic and clinical data and side of bronchial artery/non-bronchial systemic artery hypertrophy and coil embolization were documented. Results In this retrospective multicenter study 33 patients with massive hemoptysis were included for bronchial artery/non-bronchial systemic artery diameter measurements, (13 female, 20 male, median age 30 years (18–55)). Bronchial artery diameters were significantly larger in the case group than in the control group with median 4 mm (2.2–8.2 mm), and median 3 mm (1–7 mm), respectively (p = 0.002). Sensitivity of bronchial arteries ≥ 3.5 mm to be associated with hemoptysis was 0.76 and specificity 0.71 with ROC creating an area under the curve of 0.719. If non-bronchial systemic arteries were present, they were considered culprit and embolized in 92% of cases. Conclusion Bronchial arteries ≥ 3.5 mm and presence of hypertrophied non-bronchial systemic arteries correlate with massive hemoptysis in patients with CF and might serve as risk predictor for massive hemoptysis. Therefore, in patients with advanced CF we propose CT scans to be carried out as CT angiography to search for bronchial arteries ≥ 3.5 mm and for hypertrophied non-bronchial systemic arteries as possible risk factors for massive hemoptysis.

Abstract
Rasmussen's aneurysm is a pseudoaneurysm caused by tuberculosis, when cavitation occurs adjacent to a pulmonary artery, which can be lethal. It is a rare complication usually affecting adults. This is a case of an 9-year-old boy initially admitted for pneumonia that developed hemoptysis during admission. Chest X-ray done after this episode showed development of a left hilar mass not present in the previous studies. A chest CT with contrast subsequently revealed a saccular aneurysm arising from the left lower lobe pulmonary artery adjacent to a cavity, a Rasmussen's aneurysm. The patient was treated conservatively with continuation of anti-TB medication and serial monitoring due to the size of the aneurysm being less than 6 cm and spontaneous resolution of the hemoptysis. This report stresses that a Rasmussen's aneurysm should always be in the differential diagnosis of a hilar mass in a patient with hemoptysis, regardless of the patient's age.

Abstract
BACKGROUND & OBJECTIVES Haemoptysis in children is potentially life-threatening. In most cases, the bleeding arises from the systemic circulation, and in 5-10 per cent of cases, it arises from the pulmonary circulation. The role of computed tomography angiography (CTA) in this setting is important. This study was undertaken (i) to study the role of single-phase split-bolus dual energy contrast-enhanced multidetector row CTA (DECTA) in the evaluation of haemoptysis in children; (ii) to analyze the patterns of abnormal vascular supply in the various aetiologies encountered. METHODS A retrospective study of 86 patients who underwent split bolus DECTA for the evaluation of haemoptysis was performed. Final diagnoses were categorized as normal computed tomography, active tuberculosis (TB), post-infectious sequelae, non-TB active infection, cystic fibrosis (CF), non-CF bronchiectasis, congenital heart disease (CHD), interstitial lung disease, vasculitis, pulmonary thromboembolism and idiopathic pulmonary haemosiderosis. Abnormal bronchial arteries (BAs) and non-bronchial systemic collateral arteries (NBSCs) were assessed for number and site and their correlation with underlying aetiologies. RESULTS A total of 86 patients (45 males, age from 0.3 to 18 yr, mean 13.88 yr) were included in the study; among these only two patients were less than five years of age. The most common cause of haemoptysis was active infection (n=30), followed by bronchiectasis (n=18), post-infectious sequelae (n=17) and CHD (n=7). One hundred and sixty five abnormal arteries were identified (108 BA and 57 NBSC), and were more marked in bronchiectasis group. INTERPRETATION & CONCLUSIONS Active infections and bronchiectasis are the most common causes of haemoptysis in children. While post-infectious sequelae are less common, in patients with haemoptysis, the presence of any abnormal arteries correlates with a more frequent diagnosis of bronchiectasis. NBSCs are more common in post-infectious sequelae and CHD.

Abstract
Background Relapse after effective bronchial arterial embolization (BAE) for controlling hemoptysis is not uncommon. Studies reported diverse predictors of recurrence. However, a model to assess the probability of recurrence in non-cancer related hemoptysis patients after BAE has not been reported. This study was to develop a model to predict recurrence after BAE for non-cancer related hemoptysis. Methods The study cohort included 487 patients who underwent BAE for non-cancer-related hemoptysis between January 2015 and December 2019. We derived the model’s variables from univariate and multivariate Cox regression analyses. The model presented as a nomogram scaled by the proportional regression coefficient of each predictor. Model performance was assessed with respect to discrimination and calibration. Results One-month and 1-, 2-, 3- and 5-year recurrence-free rates were 94.5%, 88.0%, 81.4%, 76.2% and 73.8%, respectively. Risk factors for recurrence were underlying lung diseases and the presence of systemic arterial-pulmonary circulation shunts. This risk prediction model with two risk factors provided good discrimination (area under curve, 0.69; 95% confidence interval, 0.62–0.76), and lower prediction error (integrated Brier score, 0.143). Conclusion The proposed model based on routinely available clinical and imaging features demonstrates good performance for predicting recurrence of non-cancer-related hemoptysis after BAE. The model may assist clinicians in identifying higher-risk patients to improve the long-term efficacy of BAE.

Abstract
BACKGROUND Although bronchial arteries are the most common cause of hemoptysis, other systemic arteries can cause hemoptysis and are potential pitfalls for successful embolization. CASE REPORT We present 6 cases of hemoptysis showing vascularization from systemic arteries other than bronchial arteries that presented to our department between 2013 and 2020. Chronic inflammatory diseases such as tuberculosis and pulmonary aspergillosis were the underlying diseases in 4 of the 6 cases. In all 6 cases, the lesions were close to the pleura. The abnormal non-bronchial systemic arteries were the internal thoracic artery in 4 cases, intercostal artery in 2 cases, lateral thoracic artery in 2 cases, and the subclavian, thyrocervical, and inferior phrenic arteries in 1 case each, all of which formed a shunt with the pulmonary artery. Additionally, depending on the location of the lesion, the non-bronchial systemic arteries near the lesion proliferated into the lung parenchyma through the adherent pleura. CONCLUSIONS When lesions are in contact with the pleura, various non-bronchial systemic arteries near the lesion can develop in the pulmonary parenchyma via the adherent pleura, which can cause hemoptysis. In patients with hemoptysis, it may be useful to evaluate chest contrast-enhanced computed tomography and angiography, while always accounting for the potential involvement of non-bronchial systemic arteries to ensure a safer and more reliable treatment.

Abstract
OBJECTIVE To develop and validate a nomogram for predicting recurrent hemoptysis after successful bronchial arterial embolization (BAE) in patients with bronchiectasis. MATERIALS AND METHODS From January 2015 to December 2019, a total of 251 patients were enrolled in this study. A nomogram was developed with the predictors of recurrent events, which were identified by univariate and multivariate Cox regression analyses. We evaluated nomogram discrimination by area under the receiver operating characteristic curve, calibration by the calibration curve, and clinical usefulness potential by decision curve analysis. RESULTS The one-month, 1-year, 2-year, 3-year, and 5-year cumulative recurrence-free rates of patients were 98.4%, 90.5%, 82.8%, 77.7%, and 74.4%, respectively. Three predictive factors, namely sex, lung destruction, and systemic arterial-pulmonary circulation shunts, were applied to develop the nomogram. The model maintained good discrimination (area under the curve, 0.72; 95% confidence interval, 0.62-0.81), low prediction error (integrated Brier score, 0.129), and certain net benefits in terms of clinical usefulness. CONCLUSIONS The proposed nomogram showed favorable predictive efficacy for hemoptysis recurrence after BAE in patients with bronchiectasis. Improved long-term outcomes are expected with close follow-up, a healthy lifestyle, and pulmonary rehabilitation for patients at risk of recurrence according to the model.

Abstract
ABSTRACT Mycobacterium infection remains a leading cause of morbidity and mortality worldwide. Although rare, thoracic cardiovascular complications are associated with devastating consequences if not promptly diagnosed using computed tomography. Intrapulmonary complications include tuberculous aortitis, Rasmussen aneurysms, involvement of bronchial and nonbronchial systemic arteries, and thromboembolic events. Extrapulmonary complications include pericarditis, myocarditis, endocarditis, involvement of coronary arteries, annular-subvalvular left ventricle aneurysms and mediastinal fibrosis. This article will review these complications and their computed tomography features.

Abstract
OBJECTIVE The aim of this study was to investigate the diagnostic performance of detecting systemic arterial pulmonary circulation shunts on multidetector row computed tomography arteriography (MDCTA). METHODS Thirty-five consecutive bronchial artery embolization sessions with preprocedural MDCTA were performed for 32 patients and 35 sessions. The MDCTA studies with computed tomography value of pulmonary trunk visually lower than that of ascending aorta were defined as "diagnostic MDCTA." Angiographic studies and "diagnostic MDCTA" were evaluated, respectively, for shunting into pulmonary artery. Based on the results of angiographic studies, diagnostic performance of "diagnostic MDCTA" was evaluated. RESULTS The rate of diagnostic MDCTA was 63% (23 of 35). On "diagnostic MDCTA," sensitivity, specificity, and positive and negative predictive values for detecting shunts were 83% 100%, 100%, 94%, respectively. CONCLUSIONS Systemic arterial pulmonary circulation shunts were detected on "diagnostic MDCTA" with high sensitivity and specificity.

Abstract
PURPOSE To investigate radiographic indications and relevant clinical symptoms of retrograde systemic-to-pulmonary artery shunt (RSPAS). METHODS Forty-six consecutive patients, with transpleural systemic arterial supply to the lung confirmed by surgery or conventional angiography, underwent chest computed tomography angiography (CTA). Patients with the finding of RSPAS in CT scans were compared with those among whom no retrograde systemic-to-pulmonary artery shunt (NRSPAS) was present. Differences in clinical features, distribution and diameters of systemic supplying arteries between RSPAS and NRSPAS were assessed. RESULTS RSPAS in twenty patients (8 left and 12 right) and NRSPAS in 26 patients (14 left and 12 right) were detected at CTA. Hemoptysis and sputum were more frequent in RSPAS (85 % and 60 %, respectively) than in NRSPAS (46 % and 31 %, respectively) (P < 0.05). Single systemic supplying artery was more common in NRSPAS (65 %) while multiple systemic arteries were more frequent in RSPAS (65 %) (P < 0.05). The mean diameter of systemic arteries (6.13 ± 0.57 mm) in RSPAS was significantly larger than that (4.26 ± 0.55 mm) in NRSPAS (P < 0.0001). The anatomic location of systemic arteries crossing the thickened pleura distributed more intensively in apical and costal pleura in RSPAS than that in NRSPAS (P < 0.05). The distribution of systemic arteries adjacent to left or right lung was not statistically significant between RSPAS and NRSPAS. CONCLUSION Radiographic features of RSPAS are different from NRSPAS. RSPAS may include enlarged and multiple systemic supplying arteries. And that may suggest greater risk of hemoptysis.

Abstract
Haemoptysis is concerning for both patient and healthcare provider and points to the presence of severe underlying lung disease warranting investigation. Approximately 8% of patients with pulmonary tuberculosis (PTB) infection will experience haemoptysis at some point during their life [1;2]. The aetiology of haemoptysis in the setting of PTB is diverse and may occur during active or following prior PTB infection due to pulmonary complications. We describe the case of a 33-year-old female who presented with massive haemoptysis on two separate occasions within a five-month period. Her background history included PTB 6 years prior and subsequent post-TB bronchiectasis with a destroyed left lung, and the development of apical mycetoma's. Despite numerous pre-existing aetiologies that could account for haemoptysis in this patient, on this admission, a newly identified ruptured Rasmussen's aneurysm was identified by angiography and successfully treated with arterial embolization. This report serves to highlight the multitude of reasons for haemoptysis in a patient with post PTB lung destruction and the associated diagnostic challenges that may be present. In particular, we highlight the Rasmussen's aneurysm, a rare entity, as a hidden cause of haemoptysis, where despite extensive parenchymal lung disease identified on chest radiography, specialised imaging is needed to confirm the diagnosis.

Abstract
Massive hemoptysis is regarded as a potentially lethal condition that requires immediate attention, and prompt action. Although minor hemoptysis is frequently encountered by most clinicians, massive hemoptysis in far less frequent and most physicians are not prepared to manage this time-sensitive clinical presentation in a systematic and timely fashion. Critical initial steps in management need to be implemented in an expedited fashion, such that patients may have a chance at a more definitive treatment. In this article, we review the definition, vascular anatomy, etiology, diagnostic evaluation, epidemiology and prognostic markers of massive hemoptysis. A systematic approach to management, stabilization and treatment options is followed. An algorithm is proposed for the management of massive hemoptysis and the importance of a multidisciplinary approach is emphasized.

Abstract
The circulation of the lung is unique both in volume and function. For example, it is the only organ with two circulations: the pulmonary circulation, the main function of which is gas exchange, and the bronchial circulation, a systemic vascular supply that provides oxygenated blood to the walls of the conducting airways, pulmonary arteries and veins. The pulmonary circulation accommodates the entire cardiac output, maintaining high blood flow at low intravascular arterial pressure. As compared with the systemic circulation, pulmonary arteries have thinner walls with much less vascular smooth muscle and a relative lack of basal tone. Factors controlling pulmonary blood flow include vascular structure, gravity, mechanical effects of breathing, and the influence of neural and humoral factors. Pulmonary vascular tone is also altered by hypoxia, which causes pulmonary vasoconstriction. If the hypoxic stimulus persists for a prolonged period, contraction is accompanied by remodeling of the vasculature, resulting in pulmonary hypertension. In addition, genetic and environmental factors can also confer susceptibility to development of pulmonary hypertension. Under normal conditions, the endothelium forms a tight barrier, actively regulating interstitial fluid homeostasis. Infection and inflammation compromise normal barrier homeostasis, resulting in increased permeability and edema formation. This article focuses on reviewing the basics of the lung circulation (pulmonary and bronchial), normal development and transition at birth and vasoregulation. Mechanisms contributing to pathological conditions in the pulmonary circulation, in particular when barrier function is disrupted and during development of pulmonary hypertension, will also be discussed.

Abstract
Hemoptysis is the expectoration of blood that originates from the lower respiratory tract. It is usually a self-limiting event but in fewer than 5% of cases it may be massive, representing a life-threatening condition that warrants urgent investigations and treatment. This article aims to provide a comprehensive literature review on hemoptysis, analyzing its causes and pathophysiologic mechanisms, and providing details about anatomy and imaging of systemic bronchial and nonbronchial arteries responsible for hemoptysis. Strengths and limits of chest radiography, bronchoscopy, multidetector computed tomography (MDCT), MDCT angiography and digital subtraction angiography to assess the cause and lead the treatment of hemoptysis were reported, with particular emphasis on MDCT angiography. Treatment options for recurrent or massive hemoptysis were summarized, highlighting the predominant role of bronchial artery embolization. Finally, a guide was proposed for managing massive and nonmassive hemoptysis, according to the most recent medical literature.

Abstract
Hemoptysis can be a life-threatening condition that warrants urgent investigation and intervention. Common causes include bronchiectasis, chronic obstructive pulmonary disease, tuberculosis, and malignancy. Computed tomography angiography is an accurate imaging modality for assessment of hemoptysis. The bronchial arteries are the source of bleeding in most cases of hemoptysis, and bronchial artery embolization is the treatment of choice. The aim of this article is to summarize the pathophysiology, causes, initial management, and diagnostic approach of hemoptysis. Endovascular treatment of hemoptysis, technique, embolic materials, outcomes, complications, and follow-up of patients are discussed.

Abstract
Background: Hemoptysis in patients with advanced lung cancer can be a life threatening. Objectives: To evaluate immediate outcomes and late outcomes of bronchial artery embolization (BAE) for palliative treatment in patients with advanced nonsmall-cell lung cancer (NSCLC) having hemoptysis. Methods: The BAE was performed in 28 patients with NSCLC. Hemoptysis was defined as follows: massive bleeding greater than 300 mL within 24 hours (n = 8), moderate bleeding of 100 to 300 mL within 24 hours (n =12), and slight bleeding less than100 mL within 24 hours (n = 8). Results: Success rate was 96%. Immediate clinical success within 24 hours after BAE was achieved in 22 of the 27 patients who underwent embolization. Conclusions: The BAE with gelatin sponge particles can provide good management of hemoptysis as a palliative treatment in patients with advanced NSCLC.

Abstract
Hemoptysis is an uncommon but distressing symptom in children. It poses a diagnostic challenge as it is difficult to elicit a clear history and perform thorough physical examination in a child. The cause of hemoptysis in children can vary with the child's age. It can range from infection, milk protein allergy and congenital heart disease in early childhood, to vasculitis, bronchial tumor and bronchiectasis in older children. Acute lower respiratory tract infections are the most common cause of pediatric hemoptysis. The objective of imaging is to identify the source of bleeding, underlying primary cause, and serve as a roadmap for invasive procedures. Hemoptysis originates primarily from the bronchial arteries. The imaging modalities available for the diagnostic evaluation of hemoptysis include chest radiography, multi-detector computed tomography (MDCT), magnetic resonance imaging (MRI) and catheter angiography. Chest radiography is the initial screening tool. It can help in lateralizing the bleeding with high degree of accuracy and can detect several parenchymal and pleural abnormalities. However, it may be normal in up to 30% cases. MDCT is a rapid, non-invasive multiplanar imaging modality. It aids in evaluation of hemoptysis by depiction of underlying disease, assessment of consequences of hemorrhage and provides panoramic view of the thoracic vasculature. The various structures which need to be assessed carefully include the pulmonary parenchyma, tracheobronchial tree, pulmonary arteries, bronchial arteries and non-bronchial systemic arteries. Since the use of MDCT entails radiation exposure, optimal low dose protocols should be used so as to keep radiation dose as low as reasonably achievable. MRI and catheter angiography have limited application.

Abstract
Life-threatening hemoptysis is a severe condition that requires rapid diagnosis and treatment. One of the treatments of choice is embolization. The initial assessment aims to locate the origin and cause of bleeding. The technological advance of the development of multidetector computed tomography (MDCT) has changed the management of patients with life-threatening hemoptysis. MDCT angiography makes it possible to evaluate the cause of bleeding and locate the vessels involved both rapidly and noninvasively; it is particularly useful for detecting ectopic bronchial arteries, nonbronchial systemic arteries, and pulmonary pseudoaneurysms. Performing MDCT angiography systematically before embolization enables better treatment planning. In this article, we review the pathophysiology and causes of life-threatening hemoptysis (including cryptogenic hemoptysis) and the MDCT angiography technique, and we review how to systematically evaluate the images (lung parenchyma, airways, and vascular structures).

Abstract
BACKGROUND Non-bronchial systemic arteries can be a significant source of massive hemoptysis in patients with marked pleural involvement. However, in some cases without pleural involvement, the pulmonary ligament artery (PLA) can also enter the abnormal lung parenchyma and be responsible for hemoptysis. PURPOSE To discuss the factors influencing the development of a blood supply from the PLA in patients with hemoptysis. MATERIAL AND METHODS Seventy-five consecutive patients who underwent bronchial artery embolization (BAE) for massive hemoptysis were evaluated between January 2006 and December 2011 retrospectively. Selective arteriography showed an enlarged and tortuous PLA in five patients. CT was done to determine the site and extent of the underlying diseases before BAE in all patients. Angiographic and CT images were analyzed to determine if there was a relationship between PLA supply and location of the underlying disease or mediastinal pleural involvement. RESULTS The underlying lesions of six patients involved the basal segments of the lower lobe without marked mediastinal pleural thickening or adhesion, but diaphragmatic and lateral pleural thickening was observed in one case. Of these six patients, the PLA supplied blood to the lesions related to the hemoptysis in five patients. No patient with massive hemoptysis whose underlying lesions involved other segments of lung had a PLA supplying the lesions. CONCLUSION Even though pleural involvement is absent, underlying lesions involving the basal segments of the lower lobe could be a good indicator that the PLA is the cause of bleeding in patients with massive hemoptysis.

Abstract
AIM To explore the anatomical relationships between bronchial artery and tracheal bifurcation using computed tomography angiography (CTA). METHODS One hundred consecutive patients (84 men, 16 women; aged 46-85 years) who underwent CTA using multi-detector row CT (MDCT) were investigated retrospectively. The distance between sites of bronchial artery ostia and tracheal bifurcation, and dividing directions were explored. The directions of division from the descending aorta were described as on a clock face. RESULTS We identified ostia of 198 bronchial arteries: 95 right bronchial arteries, 67 left bronchial arteries, 36 common trunk arteries. Of these, 172 (87%) divided from the descending aorta, 25 (13%) from the aortic arch, and 1 (0.5%) from the left subclavian artery. The right, left, and common trunk bronchial arteries divided at -1 to 2 cm from tracheal bifurcation with frequencies of 77% (73/95), 82% (54/66), and 70% (25/36), respectively. The dividing direction of right bronchial arteries from the descending aorta was 9 to 10 o'clock with a frequency of 81% (64/79); that of left and common tract bronchial arteries was 11 to 1 o'clock with frequencies of 70% (43/62) and 77% (24/31), respectively. CONCLUSION CTA using MDCT provides details of the relation between bronchial artery ostia and tracheal bifurcation.

Abstract
Bronchial artery angiography with embolization has become a mainstay in the treatment of hemoptysis. Major complications are rare and immediate clinical success defined as cessation of hemorrhage ranges in most series from 85% to 100%, although recurrence of hemorrhage ranges from 10% to 33%. Bronchial artery embolization offers a minimally invasive procedure for even the most compromised patient serving as first-line treatment for hemorrhage as well as providing a bridge to more definitive medical or surgical intervention focused upon the etiology of the hemorrhage. The aim of this article is to summarize the etiologies, pathophysiology, and the diagnostic and management strategies of hemoptysis as related to bronchial artery embolization. In addition, the techniques of arteriography and embolization as well as associated procedural outcomes and complications are delineated.

METHODS 64-detector row helical CT and conventional angiography of the thorax were performed in 28 patients (25 males, 3 females; age range, 18-65 years; mean age, 40 years) with life-threatening haemoptysis. CT images were analysed to identify abnormal bronchial and non-bronchial systemic arteries and also to localise them in two planes. RESULTS Using multidetector CT (MDCT), 43 bronchial arteries were identified on the right side and 46 on the left side. 89% of the right bronchial arteries originated from the right intercostobronchial arteries. A common trunk of origin of the right and left bronchial artery was noted in 46% of cases. 23 non-bronchial systemic arteries were noted on the right side and 41 on the left side. Pleural thickening >3 mm was confirmed to be a good predictor of non-bronchial systemic supply. An internal mammary artery diameter of >3 mm and an inferior phrenic artery diameter of >2 mm were sensitive indicators for non-bronchial systemic supply. CONCLUSION MDCT is a good investigation tool for evaluating life-threatening haemoptysis as it confirms the disease process, identifies the origin and ostial position of bronchial arteries, detects non-bronchial systemic arteries and acts as a roadmap for percutaneous transcatheter embolisation.

Abstract
AIM: To explore the anatomical relationships between bronchial artery and tracheal bifurcation using computed tomography angiography (CTA).
METHODS: One hundred consecutive patients (84 men, 16 women; aged 46-85 years) who underwent CTA using multi-detector row CT (MDCT) were investigated retrospectively. The distance between sites of bronchial artery ostia and tracheal bifurcation, and dividing directions were explored. The directions of division from the descending aorta were described as on a clock face.
RESULTS: We identified ostia of 198 bronchial arteries: 95 right bronchial arteries, 67 left bronchial arteries, 36 common trunk arteries. Of these, 172 (87%) divided from the descending aorta, 25 (13%) from the aortic arch, and 1 (0.5%) from the left subclavian artery. The right, left, and common trunk bronchial arteries divided at -1 to 2 cm from tracheal bifurcation with frequencies of 77% (73/95), 82% (54/66), and 70% (25/36), respectively. The dividing direction of right bronchial arteries from the descending aorta was 9 to 10 o’clock with a frequency of 81% (64/79); that of left and common tract bronchial arteries was 11 to 1 o’clock with frequencies of 70% (43/62) and 77% (24/31), respectively.
CONCLUSION: CTA using MDCT provides details of the relation between bronchial artery ostia and tracheal bifurcation.

Abstract
Bronchial artery bleeding is the most common cause of life-threatening hemoptysis. The most common underlying etiologies include tuberculosis, bronchiectasis, aspergillosis, and cystic fibrosis. Bronchial artery embolization is an important treatment for significant hemoptysis, given its high early success rate and relatively low risk compared with alternative medical and surgical treatments. In this article, the relevant anatomy and pathophysiology leading to bronchial artery bleeding is discussed, including the roles of parenchymal lung diseases and of collateral and aberrant vessels. The indications for treatment, success rate, and complication rate for bronchial artery embolization are reviewed. Preprocedure clinical stabilization and evaluation, including the roles of radiographs, bronchoscopy, and computed tomography examination are evaluated. Details of technique, including the published variety of approaches, and an emphasis on avoidance of nontarget embolization of important mediastinal structures and of the anterior spinal artery are discussed.

Abstract
UNLABELLED BACKGROUND; Hemoptysis can be an acute medical emergency, which can be localized angiographically and controlled by therapeutic intervention. PURPOSE To evaluate the effectiveness and safety of bronchial artery embolization, and including follow-up in patients with hemoptysis. MATERIAL AND METHODS Thirty-five vascular interventions were performed in 28 patients (nine women and 19 men, mean age 42 years, age range 20-82 years) treated for hemoptysis between January 1998 and October 2008. Underlying diseases were cystic fibrosis (n = 9), lung cancer (n = 6), chronic inflammatory disease (n = 4), bronchiectasis (n = 3), chronic obstructive pulmonary disease (n = 2), and other (n = 4). Bronchial artery embolization was performed using particles. Patients were followed up for a median of 23 months (range 1 month to 8 years). RESULTS Bronchial artery embolization was technically successful in all patients (bleeding halted within 24 hours). Recurrent bleeding occurred in four patients with cystic fibrosis (14%) at one, 16, 19 and 48 months, respectively. Within this subset, multirecurrence bleeding occurred in one patient with cystic fibrosis. Cumulative patient survival rate was 74% at eight years. No patient died due to hemoptysis but due to underlying disease. CONCLUSION Bronchial artery embolization was highly effective in patients with hemoptysis. It may help to avoid surgery in patients who are poor candidates for surgery. Should hemoptysis recur in these patients, repeated embolization can be performed.

Abstract
Hemoptysis is defined as the expectoration of blood originating from the tracheobronchial tree or pulmonary parenchyma, ranging from 100 mL to 1 L in volume over a 24-hour period. This article reviews the literature on the indications and usefulness of radiologic studies for the evaluation of hemoptysis. The following recommendations are the result of evidence-based consensus by the American College of Radiology Appropriateness Criteria Expert Panel on Thoracic Radiology: (1) Initial evaluation of patients with hemoptysis should include a chest radiograph; (2) Patients at high risk for malignancy (>40 y old, >40 pack-year smoking history) with negative chest radiograph, computed tomography (CT) scan, and bronchoscopy can be followed with observation for the following 3 years. Radiography and CT are recommended imaging modalities for follow-up. Bronchoscopy may complement imaging during the period of observation; (3) In patients who are at high risk for malignancy and have suspicious chest radiograph findings, CT is suggested for initial evaluation; CT should also be considered in patients who are active or exsmokers, despite a negative chest radiograph; and (4) Massive hemoptysis can be effectively treated with either surgery or percutaneous embolization. Contrast-enhanced multidetector CT before embolization or surgery can define the source of hemoptysis as bronchial systemic, nonbronchial systemic, and/or pulmonary arterial. Percutaneous embolization may be used initially to halt the hemorrhage before definitive surgery.

Abstract
Hemoptysis can be a life-threatening respiratory emergency and indicates potentially serious underlying intrathoracic disease. Large-volume hemoptysis carries significant mortality and warrants urgent investigation and intervention. Initial assessment by chest radiography, bronchoscopy, and computed tomography (CT) is useful in localizing the bleeding site and identifying the underlying cause. Multidetector CT angiography is a relatively new imaging technique that allows delineation of abnormal bronchial and nonbronchial arteries using reformatted images in multiple projections, which can be used to guide therapeutic arterial embolization procedures. Bronchial artery embolization (BAE) is now considered to be the most effective procedure for the management of massive and recurrent hemoptysis, either as a first-line therapy or as an adjunct to elective surgery. It is a safe technique in the hands of an experienced operator with knowledge of bronchial artery anatomy and the potential pitfalls of the procedure. Recurrent bleeding is not uncommon, especially if there is progression of the underlying disease process. Prompt repeat embolization is advised in patients with recurrent hemoptysis in order to identify nonbronchial systemic and pulmonary arterial sources of bleeding. This article reviews the pathophysiology and causes of hemoptysis, diagnostic imaging and therapeutic options, and technique and outcomes of BAE.

Abstract
RATIONALE Data on hemoptysis of unknown origin (i.e., "cryptogenic") are scarce and the outcome of patients affected is controversial. OBJECTIVES To describe the clinical spectrum and course of patients with cryptogenic hemoptysis, as well as pathologic findings when surgery is performed. METHODS A cohort of 81 patients referred for cryptogenic hemoptysis after clinical evaluation, chest radiography, fiberoptic bronchoscopy, and computed tomographic scan to a respiratory intermediate care and intensive care unit, from December 1995 to August 2004, with a prospective follow-up by visit or telephone interview. MEASUREMENTS AND MAIN RESULTS The 81 patients (69 males) had a mean cumulative volume of hemoptysis averaging 190 ml on admission. First-line conservative measures and bronchial artery embolization controlled hemoptysis in 73 patients (90%). Emergency surgery was performed in six patients (7%) because of failure of bronchial artery embolization, and secondary surgery was scheduled in a seventh patient. A total of 73 patients were followed for a mean of 47 (+/- 35) months. No lung cancer developed. Hemoptysis recurred in 10 patients (4 within the first year; 6 between 1 and 8 yr later), 2 of whom underwent surgery. A specific bronchial vascular involvement (Dieulafoy disease) was demonstrated in five of the nine patients who had undergone surgery, especially in those with high amounts of bleeding. CONCLUSIONS Cryptogenic hemoptysis may be a life-threatening condition. Nonsurgical approaches provide immediate control of bleeding in most patients with cryptogenic hemoptysis, with few recurrences in both short and long terms. Dieulafoy disease of the bronchus, unsuspected after routine imaging investigations, may be involved in a subset of patients yet to be determined.

Abstract
The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period (2000-2005), 251 consecutive patients with hemoptysis underwent multidetector-row CT angiography of the thorax. From this population, 37 patients were excluded because of a suboptimal CTA examination (n = 19), the presence of extensive mediastinal disease (n = 15) or severe chest deformation (n = 3) precluding any precise analysis of the bronchial arteries at CTA. Our final study group included 214 patients who underwent a thin-collimated CT angiogram (contrast agent: 300 to 350 mg/ml) on a 4- (n = 56), 16- (n = 119) and 64- (n = 39) detector-row scanner. The site of origin and distribution of bronchial arteries were analyzed on transverse CT scans, maximum intensity projections and volume-rendered images. The site of the ostium of a bronchial artery was coded as orthotopic when the artery originated from the descending aorta between the levels of the fifth and sixth thoracic vertebrae; all other bronchial arteries were considered ectopic. From the studied population, 137 (64%) patients had only orthotopic bronchial arteries, whereas 77 patients (36%) had at least one bronchial artery of ectopic origin. A total of 147 ectopic arteries were depicted, originating as common bronchial trunks (n = 23; 19%) or isolated right or left bronchial arteries (n = 101; 81%). The most frequent sites of origin of the 124 ostiums were the concavity of the aortic arch (92/124; 74%), the subclavian artery (13/124; 10.5%) and the descending aorta (10/124; 8.5%). The isolated ectopic bronchial arteries supplied the ipsilateral lung in all but three cases. Bronchial artery embolization was indicated in 26 patients. On the basis of CTA information, (1) bronchial embolization was attempted in 24 patients; it was technically successful in 21 patients (orthotopic BAs: 6 patients; orthotopic and ectopic BAs: 3 patients; ectopic BAs: 12 patients) and failed in 3 patients due to an instable catheterization of the ectopic BAs; the absence of additional bronchial arterial supply and no abnormalities of nonbronchial systemic arteries at CTA avoided additional arteriograms in these 3 patients; (2) owing to the iatrogenic risk of the embolization procedure of ectopic BAs, the surgical ligation of the abnormal vessels was the favored therapeutic option in 2 patients. This study enabled the depiction of ectopic bronchial arteries in 36% of the studied population, important anatomical information prior to therapeutic decision making.
