Abstract
We treated a patient with an aortoenteric fistula (AEF), and report this case. A 67-year-old man with hematemesis and melena was admitted to our hospital. Gastroduodenal fiberscopic examinations could not reveal a bleeding focus. Computed tomography (CT) showed an abodominal aortic aneurysm (AAA) measuring 45 mm in diameter. We suspected AEF and planned the semi-emergency operation. However, since he fell into the shock state, the emergency surgery was required. Intraoperatively, we confirmed an AEF between an AAA and the duodenum. We performed the abdominal aorta replacement and the duodenal repair. In order to reduce the risk of infectious complications such as a graft infection, a pedicled omentum was used to cover the prosthetic graft. Though he was complicated with catheter-associated bacteremia, he was discharged 74 days later.
