[Endovascular repair of primary aortoenteric fistula]

Aortoenteric fistulas are a rare, but often fatal cause of gastrointestinal bleeding. This report describes the use of endovascular aneurysmal repair (EVAR) for the initial treatment of gastrointestinal bleeding possibly related to an aortoenteric fistula. A 69-year-old man with an abdominal aortic aneurysm was admitted to our hospital because of melena. He initially underwent EVAR. Upper and lower endoscopic examination failed to detect a bleeding site. Twenty-five days later, a fever of 38 degrees C developed, and endograft infection was diagnosed. The patient underwent an extra-anatomic bypass and total endograft explantation. He remains well 9 months after EVAR
