An aortoenteric fistula is a connection between the aorta and the intestines, stomach, or esophageus.[1] There can be significant blood loss into the intestines resulting in bloody stool and death.[1] It is usually secondary to an abdominal aortic aneurysm repair.

Diagnosis

Diagnosis is typically via a CT angiography, esophagogastroduodenoscopy, or arteriography.[1] It is part of the differential diagnosis of gastrointestinal bleeding.[2]
