Successful endovascular treatment with long-term antibiotic therapy for infectious pseudoaneurysm due to Klebsiella pneumoniae: A case report

Figure 1 Findings of chest computed tomography. A: Three weeks before the patient was transferred to our hospital, chest computed tomography showed pulmonary consolidation and pleural effusion; B: Upon admission to our hospital, chest computed tomography showed that pulmonary infection had alleviated, but some inflammatory infiltrations were present.

Figure 2 Preoperative computed tomography angiography. A: A pseudoaneurysm of the common femoral artery compressed its distal outflow tract (orange arrow); B: Occlusion of the superficial femoral artery and deep femoral artery.

Figure 3 Intraoperative digital subtraction angiography. A: Guidewires cannot pass through the occlusion lesion; B: Retrograde access was achieved at the superficial femoral artery; C: Pathway was established via the “SAFARI” technique; D: After stent–grafts were deployed, the stent–grafts and distal outflow tract were patent without any endoleaks.

Figure 4 Computed tomography angiography at the 1-year follow-up. A: Stent–grafts were patent without any endoleaks; B and C: The previous surrounding hematoma was completely absorbed.
