Secondary aortoenteric fistula is a rare yet fatal condition that may occur as a complication after abdominal aortic aneurysm repair. Here, we report a case of a 66‑year‑old male with abdominal discomfort and intermittent fever at 5 years after endovascular aortic repair of an infected abdominal mycotic aneurysm. Surgical treatment with extra‑anatomic bypass for lower body revascularization, followed by exploratory laparotomy with explantation of the infected graft and aortic tissue and repair of the duodenum were performed. The patient was rescued from the septic condition and discharged uneventfully 2 months postoperatively.
