Repair of a high-flow superficial femoral arteriovenous fistula using a bell-bottom iliac limb endoprosthesis

A 50-year-old patient had presented with recalcitrant right lower extremity venous stasis ulceration, atrial fibrillation, and congestive heart failure. He had a history of a gunshot wound to the right thigh >30 years previously, which had been managed without surgery. Computed tomography angiography indicated a fistulous communication between the right superficial femoral artery and vein with massively dilated right iliofemoral venous and arterial systems. He was treated with stent-graft coverage of the superficial femoral arteriovenous fistula using a bell-bottom iliac limb endoprosthesis. This stent-graft accommodated the diameter asymmetry in the superficial femoral artery caused by the long-standing fistula and ameliorated the symptoms that had afflicted him for decades.
