Successful endovascular treatment of aortoenteric fistula secondary to eroding duodenal stent.

Aortoenteric fistulas are characterized as either primary or secondary on the basis of their cause. Most aortoenteric fistulas occur between the aorta and duodenum and are a rare but well-known cause of catastrophic gastrointestinal hemorrhage. Conventional treatment of aortoenteric fistulas uses bypass grafting and aortic ligation, but endovascular treatments have become more common. The authors describe the successful endovascular repair of a primary aortoenteric fistula caused by eroding duodenal stent.
