Aortoduodenal Fistula Arising 6 Months after Endovascular Abdominal Aortic Aneurysm Repair without Endoleak

Abstract

We report a case of aortoduodenal fistula 6 months after uncomplicated endovascular abdominal aortic aneurysm repair. The diagnosis was confirmed by abdominal computed tomography scan. The patient was successfully treated with primary duodenal repair, removal of the infected stentgraft, in situ placement of a bifurcated graft. Aortoduodenal fistula occurred despite accurate stent graft placement without endoleak, or aortic sac size enlargement on postoperative imaging studies.
