Aortoenteric fistula following endovascular abdominal aortic aneurysm repair.

Aortoenteric fistula is a rare complication after endovascular stent grafting. In the present report, we have described the case of a 69-year-old man 3 years after endovascular repair of an abdominal aortic aneurysm who had presented with worsening back pain and fever. Computed tomography had demonstrated dilated bowel and a thickened aortic wall, with air foci within the native aneurysm sac. He underwent emergent right axillary-bifemoral bypass with explantation of the aortic endograft and primary repair of the duodenal fistula. Tissue cultures grew and , and he was discharged home with 6 weeks of intravenous ceftriaxone and oral metronidazole after an 18-day hospital admission.
