    Author: Doney MK, Vilke GM.
    Journal: J Emerg Med; 2012 Sep; 43(3):431-4. PubMed ID: 20097507.
    Abstract:
    BACKGROUND: Aortoenteric fistula (AEF) is a rare but life-threatening condition in which expedient diagnosis is often difficult. It arises from erosion of a segment of aorta, usually an abdominal aortic aneurysm, into an adjacent portion of the gastrointestinal tract or between a vascular graft of the aorta and an adjacent portion of the gastrointestinal tract. It can present as life-threatening upper or lower gastrointestinal bleeding and is a surgical emergency that requires rapid assessment, emergency resuscitation, and definitive treatment. CASE REPORT: To present the case of an 87-year-old man diagnosed with AEF in the emergency department. A review of the literature follows the case report. CONCLUSIONS: Aortoenteric fistula is a rare diagnosis that can cause sudden life-threatening gastrointestinal bleeding.
