Primary aortoduodenal fistula supplied by type II endoleak.

ABSTRACT

Aortoenteric fistulas are a rare but potentially lethal condition. Here we present an unusual case of a fistula between the excluded portion of an infrarenal aneurysm repaired by stent-grafting and the duodenum. The fistula was supplied by a type II endoleak. The patient was successfully treated by extra-anatomic bypass grafting and removal of the aneurysm sac and the stent-graft.
