Summary
Aortoenteric fistula, a rare complication after aortic aneurysm repair, can occur even with a thrombosed graft. This case highlights a delayed diagnosis due to the unexpected fistula formation pathway.
Area of Science:
- Vascular Surgery
- Gastroenterology
Background:
- Aortoenteric fistula is a rare but serious complication following abdominal aortic aneurysm repair.
- Typically, continuous friction and inflammation cause fistulas, but formation with a thrombosed graft is unexpected.
Observation:
- A 75-year-old male presented with melena, later diagnosed with an aortoduodenal fistula.
- The fistula formed between a thrombosed aortoiliac bypass graft and the duodenum.
Findings:
- The aortoduodenal fistula was successfully repaired through graft excision, aortic oversewing, omental flap coverage, pyloric exclusion, and gastrojejunostomy.
- This case demonstrates that aortoenteric fistulas can develop through thrombosed grafts.
Implications:
- The unexpected nature of fistula formation with thrombosed grafts may lead to diagnostic delays.
- Awareness of this possibility is crucial for timely diagnosis and management of aortoenteric fistulas.
