Repair of a high-flow iliac arteriovenous fistula using a thoracic endograft.

Open surgical repair of iliac arteriovenous fistulas is associated with significant morbidity and mortality, making endovascular repair an attractive alternative. This report describes a 39-year-old man who was admitted with two-pillow orthopnea, edema, and fatigue. He had sustained a gunshot wound to the pelvis 13 years previously. Six years after the gunshot wound, he was diagnosed with cardiomegaly and high-output congestive heart failure. A magnetic resonance angiography documented a large pelvic arteriovenous fistula. A diagnostic contrast angiogram confirmed a high-flow fistula between the left distal main internal iliac artery and left common iliac vein. A Gore TAG thoracic endoprosthesis (W. L. Gore and Assoc, Flagstaff, Ariz) was used to repair this large, high-flow internal iliac artery-common iliac vein arteriovenous fistula.
