A 65-year-old man who underwent closure of a traumatic arteriovenous fistula presented with pulsating masses in the right femoral region. A diagnosis of multiple aneurysms from the right external iliac artery to the superficial femoral artery complicated by ipsilateral varicosis of the short saphenous vein was made. Stripping of the short saphenous vein and iliopopliteal bypass with reimplantation of the profunda femoris artery were performed in two stages. Hemodynamic factors are considered to be involved in the mechanism of aneurysm formation following treatments for traumatic arteriovenous fistula, and long-term follow-up is needed after their closure.
