Symptomatic Deep Femoral Artery Pseudoaneurysm Endovascular Exclusion. Case Report and Literature Review

Abstract

Deep femoral artery pseudoaneurysms (DFAPs) are rare and generally occur after penetrating trauma or surgical procedures. A 36-year-old obese man presented with pain in correspondence of the anterior-lateral thigh after 6 months from gunshot wound. Duplex and computed tomography (CT) showed a bilobed right DFAP (maximal diameter 12.9 cm). The patient was managed urgently, under local anesthesia, by placement in the distal DFA of a Viabahn 8 × 100-mm stent graft (W L Gore & Associates, Inc). The postoperative course was uneventful, and the 24-month CT showed regular stent-graft patency and 20-mm DFAP shrinkage. The literature review reported 8 cases of DFAPs; of these 6 were managed by endovascular mean (3 stent-graft implantations and 3 coil embolization). The remaining 2 cases were managed surgically (one of these after failed coil embolization). In conclusion, the use of covered stent graft was effective to treat a DFAP localized in the medium DFA. This tool allowed maintaining the native DFA patency and the preservation of its main branches.
