Delayed traumatic superficial femoral artery pseudoaneurysm and arteriovenous fistula over the left lower limb

Abstract

A pseudoaneurysm is a pulsating, encapsulated hematoma in communication with a ruptured vessel (1); there is an accumulation of blood between the tunica media and tunica adventitia layers of the vessel. We report a case of a young male with complaints of swelling, skin discoloration, and a tingling sensation of the left lower limb. A peripheral angiography was performed, which revealed an arteriovenous fistula at the middle of the left superficial femoral artery. The patient underwent a left superficial femoral artery pseudoaneurysm excision and repair. In this case report, we discuss the presenting clinical features, methods of evaluation, and the management of the superficial femoral artery pseudoaneurysm accompanied with arteriovenous fistula.
