Surgical Management for Secondary Aortoduodenal Fistula

Aortoenteric fistulas (AEFs) are uncommon but life-threatening conditions carrying a high mortality rate. This is defined as an abnormal connection between the aorta and the lumen of the gastrointestinal tract. There are two known forms of AEF, primary and secondary. Primary is most often the result of compression of an abdominal aortic aneurysm against the intestines, whereas secondary is due to an erosion of an aortic prosthetic graft into the surrounding gastrointestinal structures. The relative incidence of primary AEF ranges from 0.1 to 0.8%, and secondary from 0.4% to 2.4%.
