ABSTRACT
Aortoenteric fistula (AEF) developed after treatment for an abdominal aortic aneurysm (AAA) is a rare but usually fatal complication. We report a rare case of AEF bleeding after endovascular stent grafting for AAA which was managed angiographically. An 81-year-old man presented with hematochezia and acute abdominal pain for 1 day ago. Four years ago, an aortic stent was implanted in the infrarenal aorta for AAA. Endoscopies were performed to evaluate the hematochezia. Evidence of gastrointestinal bleeding was observed, but a clear bleeding point was not detected on upper endoscopy and colonoscopy. Contrast-enhanced computed tomography performed subsequently showed that the bleeding point was located in the fourth portion of the duodenum as an AEF caused by an inflammatory process in the stent-graft. Intra-arterial angiography showed a massive contrast leakage into the bowel via a small fistula from around the aortic stent graft site. Embolization was successfully performed by injecting a mixture of glue and lipiodol into the AEF tract. The patient was discharged with no evidence of gastrointestinal bleeding after the embolization.
