[Aortoduodenal fistula as the cause of gastrointestinal hemorrhage].

Abstract

The aortoenteric fistula is one of the rare causes of gastrointestinal bleeding. A 73 year old patient presented with a secondary fistula after implantation of a synthetic graft. The diagnosis was confirmed by endoscopy. At elective laparotomy, a communication between the graft and the duodenum was discovered. Principally the combination of gastrointestinal bleeding and aortic graft is always suspicious of an aortoenteric fistula. The treatment must be surgical.
