Aorto-Enteric Primary Fistula on Remote Endovascular Aneurysm Repair

Aorto-Enteric Fistula (AEF) can be primary or secondary to surgery. The authors describe a case of death due to acute gastrointestinal hemorrhaging, resulting in primary AEF, in a patient who had undergone surgery in the past. The site and the pathological features of the lesion allow us to recognize the primary nature of the AEF, excluding remote surgery as a possible cause. The differential diagnosis is based on the patient’s history and also on the anatomical characteristics of the lesion, such as location and extent.
