Gastrointestinal bleeding after aortic surgery: a case report

IntroductionAn aortoenteric fistula is a communication between the aorta and an adjacent loop of the bowel. Here we report a case with this rare complication with typical herald bleeding.Case report :A 66-year-old man underwent elective repair of a large supra-renal abdominal aortic aneurysm and returned 6 months later to our clinic after experiencing a melena with hematochezia.

The source of bleeding could not be identified by gastroscopy but the following day he vomited a large volume of blood, rapidly became haemodynamically unstable and died of hypotensive shock. A CT scan on the same day showed an increasing area of low-density soft tissue around the graft wall compared with the previous CT scan images obtained initially after the aortic repair.

An aortoenteric fistula was confirmed by autopsy.

Conclusion: In patients that underwent abdominal aortic surgery, both the occurrence of herald bleeding and CT findings of increasing para graft soft tissue might play a crucial role in early detection of aortoenteric fistula.
