Transjugular intrahepatic portosystemic shunt (TIPS) is a widely accepted option for treating the complications of portal hypertension. The procedure involves creating a communication between the portal and hepatic venous systems using imaging guidance, thereby diverting the portal venous flow and reducing the portosystemic gradient. However, as with any procedure, TIPS insertion is not without potential complications. We present a case of a 37-year-old female who developed a hepatic artery pseudoaneurysm following the placement of a TIPS which was successfully treated with percutaneous thrombin injection.

Clinical manifestations of liver transplantation complications can be subtle and non-specific. Medical imaging, mainly Doppler ultrasound, plays an important role to detect and grade these. Colour Doppler ultrasound exams are routinely performed at 24–48 h, on the 7th day, the first and third month after transplantation. MDCT and MR images are acquired based on the Doppler ultrasound (DUS) findings, even in the absence of abnormal liver function. As vascular complications appear early after surgery, DUS should be performed by experience personnel. Diagnostic angiography is seldom performed. This pictorial review illustrates the key imaging findings of vascular complications in patients with liver transplantation: hepatic artery complications (such as thrombosis, stenosis of the anastomosis and pseudoaneurysms), portal vein abnormalities (such as occlusion and stenosis) and hepatic veins and/or inferior vena cava flow changes (Budd-Chiari syndrome).

A 75-year-old man with chronic cholangitis and a common bile duct stone that was not previously identified was admitted for right upper quadrant pain. Acute cholecystitis with cholangitis was suspected on abdominal computed tomography (CT); therefore, endoscopic retrograde cholangiopancreatography with endonasal biliary drainage was performed. On admission day 5, hemobilia with rupture of two intrahepatic artery pseudoaneurysms was observed on follow-up abdominal CT. Coil embolization of the pseudoaneurysms was conducted using percutaneous transhepatic biliary drainage. After several days, intrahepatic artery pseudoaneurysm rupture recurred and coil embolization through a percutaneous transhepatic biliary drainage tract was conducted after failure of embolization via the hepatic artery due to previous coiling. After the second coil embolization, a common bile duct stone was removed, and the patient presented no complications during 4 months of follow-up. We report a case of intrahepatic artery pseudoaneurysm rupture without prior history of intervention involving the hepatobiliary system that was successfully managed using coil embolization through percutaneous transhepatic biliary drainage.

Hepatic artery pseudoaneurysm (HAP) incidence is rising due to more common use of endoscopic and percutaneous hepatic interventions. HAP is potentially fatal, as it could lead to sudden life-threatening hemorrhage. HAP can be intrahepatic or extrahepatic. On computed tomography angiogram (CTA) and magnetic resonance angiogram (MRA), HAP follows blood pool on multiphasic examination, with brisk arterial enhancement that washes out, similar to the abdominal aorta on later phases. We present a case of idiopathic giant HAP in an 82-year-old male. Currently, angioembolization is replacing surgery as the initial modality of choice for management of this condition.

Classically, hepatic artery pseudoaneurysms (HAPs) arise secondary to trauma or iatrogenic causes. With an increasing prevalence of laparoscopic procedures of the hepatobiliary system the risk of inadvertent injury to arterial vessels is increased. Pseudoaneurysm formation post injury can lead to serious consequences of rupture and subsequent hemorrhage, therefore intervention in all identified visceral pseudoaneurysms has been advocated. A variety of interventional methods have been proposed, with surgical management becoming the last step intervention when minimally invasive therapies have failed. The authors present a case of a HAP in a 56-year-old female presenting with jaundice and pruritis suggestive of a Klatskin’s tumor. This presentation of HAP in a patient without any significant past medical or surgical intervention is atypical when considering that the majority of HAP cases present secondary to iatrogenic causes or trauma. Multiple minimally invasive approaches were employed in an attempt to alleviate the symptomology which included jaundice and associated inflammatory changes. Ultimately, a right hepatic trisegmentectomy was required to adequately relieve the mass effect on biliary outflow obstruction and definitively address the HAP. The presentation of a HAP masquerading as a malignancy with jaundice and pruritis, rather than the classic symptoms of abdominal pain, anemia, and melena, is unique. This presentation is only further complicated by the absent history of either trauma or instrumentation. It is important to be aware of HAPs as a potential cause of jaundice in addition to the more commonly thought of etiologies. Furthermore, given the morbidity and mortality associated with pseudoaneurysm rupture, intervention in identifiable cases, either by minimally invasive or surgical interventions, is recommended.

Ruptured hepatic artery pseudoaneurysm is a rare condition that is life-threatening if not diagnosed and treated rapidly.

We present a case of a spontaneously ruptured hepatic artery pseudoaneurysm that occurred after a blunt trauma, and provide a review of the current literature on this topic.

This case study demonstrates a spontaneously ruptured hepatic artery pseudoaneurysm which emerged following a blunt trauma and it also presents current literature studies on the topic.

A man at the age of 34 years with blunt trauma dating back to 1.5 month was admitted to the emergency department of a hospital with hematemesis and epigastric tenderness. He also had a duodenal ulcer, blood in the gastric lumen and a large pseudoaneurysm that developed from the left hepatic artery. Soon after the diagnosis, the patient worsened and underwent distal gastrectomy and cholecystectomy that included removing the bleeding aneurysm.

Ruptured hepatic artery pseudoaneurysm stands as a deadly condition which has to be diagnosed and managed as soon as possible. Physicians need to take aneurysms of abdominal arteries into consideration after routine diagnostic practises as long as the cause of gastrointestinal haemorrhage is unidentified.
