POTD: Aorticenteric Fistula (AEF)

AEF must be considered in any patient with GI bleeding and history of abdominal aortic surgery. Although AEF is not the most common cause of GI bleeding in these patients, it is life threatening.

The most common location is along the third or fourth portion of the duodenum. A large abdominal aortic aneurysm can erode primarily into the duodenum at these locations, resulting in fistula formation. Fun fact: Postoperative AEF is most often associated with a graft infection.

Aortoenteric fistula can present with a sentinel or herald bleed that is minor, or with a sudden catastrophic bleed with hematemesis, melena, or hematochezia (so don’t rely on just upper or lower GI bleed).

 POTD: Aorticenteric Fistula (AEF)

There are two different types of AEF: Primary: Occurs when a chronic, untreated aortic aneurysm damages or destroys the aortic and bowel tissue. Secondary: Occurs due to inflammation of previous aortic graft surgery that is near a section of bowel. This type is much more common than primary AEF.
