Aneurysms of Gastroepiploic Artery and Vein with an Arteriovenous Fistula after Partial Gastrectomy in a Patient Presenting with Abdominal Aortic Aneurysm—Report of a Case

A case of asymptomatic right gastroepiploic artery and vein aneurysms with an arteriovenous (AV) fistula coexisting with an abdominal aortic aneurysm (AAA) is presented. A 68-year-old man was referred for treatment of AAA (6 cm in diameter) and he was incidentally diagnosed as having right gastroepiploic artery and venous aneurysms (3 cm and 8 cm in diameter, respectively) with an AV fistula. Resection of the aneurysms and closure of the fistula were successfully completed with AAA repair. He had a history of gastrectomy, and these gastroepiploic aneurysms with an AV fistula were considered a late complication due to mass ligation of vessels during gastrectomy.
