Aorto-duodenal fistula on an aortic endograft: a rare cause of late conversion after endovascular aneurysm repair.

The last few years have seen an increase in popularity of endovascular aneurysm repair because of the improvements made to the endografts design as well as experience gained by physicians, but the long-term results of this procedure are still uncertain. The majority of late complications after an endograft can be treated with an endovascular approach but, in some cases, it may need conversion to open surgery. In this paper, we discuss the case of a male patient who presented with an aorto-duodenal fistula on an endograft requiring explant. After two operations and 20 days in hospital, the patient was discharged and after 1 year he is doing well. In medical literature, there are very few reported cases of aortoenteric fistula complicating endovascular prosthesis, the diagnosis is quite difficult, surgical treatment is fairly complex consisting in endograft removal and we refer to our experience on this difficult and life-threatening operation.
