Aortoenteric fistula (AEF) is a rare cause of gastrointestinal (GI) bleeding. There are two types of AEF: primary and secondary. Primary AEF usually occurs in association with abdominal aortic aneurysm (AAA). Secondary AEF are associated to aortic grafts, normally in relation to graft infection, and represent the most common type. A high level of suspicion is essential to a prompt diagnosis. If not promptly diagnosed and treated the associated mortality is very high. The role of endovascular treatment is not yet defined. Our aim is to perform a non-systematic review of the available literature concerning etiology, clinical presentation, diagnosis and treatment of AEF.
