Posttraumatic pseudoaneurysm and arteriovenous fistula are rarely observed. Because of the imminent clinical course, early operation is usually indicated. In this study, we present a case of pseudoaneurysm in the left superficial femoral artery and arteriovenous fistula between the left superficial femoral artery and vein in the left thigh, as a result of a gunshot injury. Magnetic resonance angiography and color Doppler ultrasound were used for diagnosis. The patient underwent a successful aneurysmectomy, saphenous vein interposition and venous repair and was discharged on the eighth postoperative day.
