Aortoduodenal fistula after abdominal aortic stent graft presenting with extremity abscesses.
Aortoenteric fistula (AEF) has been described after endovascular stent graft repair of abdominal aortic aneurysms (EVAR). AEF after EVAR has been associated with aneurysm growth, endoleak, migration, and aortic inflammation. We report a patient with an AEF presenting 2 years after EVAR with two abscesses in the right leg. A computed tomographic scan showed a gas-filled thrombus lining the right limb of his graft. At conversion, no endoleak, device migration, or residual aneurysm sac was found. AEF can occur after endoluminal stent graft (ELG) in the absence of aneurysm growth, endoleak, migration, or inflammation. AEF can cause ELG infection and extremity infection.
