Superficial Femoral Artery Pseudoaneurysm Causing Extensive Deep Venous Thrombosis

Abstract

This is a case report of a fifty-six-year-old, obese, corticosteroid-dependent asthmatic who presented with a pulsatile left thigh mass, left calf and foot swelling, and two block left calf claudication. Upon investigation, he was found to have a superficial femoral artery pseudoaneurysm compressing the superficial femoral vein causing a deep venous thrombosis (DVT) of the superficial femoral, popliteal, posterior tibial, and peroneal veins. The patient underwent lytic therapy for the DVT, followed by resection of the superficial femoral artery aneurysm and reconstruction of the superficial femoral artery. The cause of the superficial femoral artery pseudoaneurysm is undetermined, since he had no history of trauma, infection, or vascular intervention. Very few cases of superfi cial femoral artery aneurysm or pseudoaneurysms have been reported in the literature. This is a unique case owing to the presentation from DVT caused by compression of the surrounding venous structures.
