Aortoiliac graft-enteric fistula presenting as gastrointestinal hemorrhage: A report on a complex case management.

This case study discusses the staged management of a 78-year-old patient presenting with life-threatening lower gastrointestinal (GI) bleeding secondary to an aortoiliac graft-enteric fistula (GEF) into the sigmoid colon on the background of an adenocarcinoma and diverticular disease. The patient had an aorto bi-iliac synthetic dacron graft repair of an abdominal aortic aneurysm (AAA) some 20 years ago. Here, we present a case of successful endovascular treatment of massive hemorrhage as a bridge to definitive second-stage dacron graft explant and autologous vein reconstruction with a simultaneous anterior resection.
