title: Aortoenteric fistula after endovascular stent grafting for an abdominal aortic aneurysm: report of a case.
abstract: We report a case of an aortoenteric fistula (AEF) developing after endovascular stent grafting (EVSG) for an abdominal aortic aneurysm (AAA). A 69-year-old male patient with a history of panperitonitis caused by rectal perforation underwent EVSG for an AAA. A follow-up contrast-enhanced computed tomography (CT) scan, done 12 months after the EVSG, confirmed shrinkage of the AAA with no endoleak. However, 19 months postoperatively, an AEF developed between the AAA and the jejunum. Although there was no endoleak on a subsequent CT scan, we noted enlargement of the AAA and inflammatory changes in the surrounding tissue. The patient was treated surgically and discharged in good health 74 days postoperatively. Thus, one should consider the possibility of this devastating complication, even in patients without an endoleak, after EVSG for AAA.
