We report a case of successful surgical treatment for an aortic anastomotic false aneurysm associated with a graft-duodenal fistula after abdominal aortic aneurysm repair. A 63-year-old man was admitted with melena and an aortic anastomotic false aneurysm after prosthetic graft replacement 8 years previously. CT scan demonstrated an aneurysm with a maximum diameter of 70 mm at the proximal anastomosis of the prosthetic graft. Gastroduodenoscopy revealed no bleeding site in the stomach or the first and second portions of the duodenum. Therefore, we performed an emergency operation under a diagnosis of an aortic anastomotic false aneurysm associated with a graft-duodenal fistula. The aneurysm was replaced with interposition of a new prosthetic graft via a thoracoabdominal approach. The fistula was repaired by covering the duodenum with the jejunum through a left pararectal laparotomy. The postoperative course was uneventful, and there was no evidence of graft infection at 14 months after the operation.
