ABSTRACT

Aortoenteric fistulas (AEF) exist as an uncommon, lethal gastrointestinal bleeding, which can start with a hidden bleeding episode that leads to severe hemorrhage. The patient is a 65-year-old male who had no reported medical conditions before developing severe gastrointestinal bleeding because of an aortoduodenal fistula associated with his infrarenal aortic aneurysm. Multiple endoscopy procedures failed to detect the bleeding source, which led to the final diagnosis from CT mesenteric angiography. The patient underwent emergency open surgery to fix the condition, but died due to multi-organ failure. The presented case illustrates the challenging nature of AEF diagnosis, along with the necessity for prompt treatment and unfavorable clinical outcomes. Quick identification of medical indicators combined with proper imaging methods must be followed by multidisciplinary team coordination to achieve better outcomes.
