Secondary Aortoenteric Fistula

Table I. Patient demographics resents a graft enteric fistula (GEF) and is the more common type of SAEF. A breakdown of the enteric wall overlying the graft resulting in bathing of the graft by enteric contents and chronic graft infection without direct involvement of a suture line represents the less common graft enteric erosion (GEE). The rare SAEFs occurring between the bowel lumen and an aortic suture line in the absence of a prosthetic graft (such as after aortic repair for trauma, aortic endarterectomy or aortic stump closure after removal of a previously placed aortic graft) are considered separately in this report, but
