Summary
A rare complication of aortic surgery, aortoenteric fistula (AEF) involves an aortic graft eroding into the gastrointestinal tract. Early diagnosis is crucial for survival, as delayed detection can be fatal.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Radiology
Background:
- Secondary aortoenteric fistulas (AEFs) and aortic graft infections are rare but life-threatening complications following aortic surgery.
- Aortobifemoral bypass grafting is a common procedure for aortoiliac occlusive disease.
Observation:
- A 77-year-old male presented with fever, abdominal pain, and inguinal swelling.
- Medical history included hypertension and prior aortobifemoral bypass grafting.
- Abdominopelvic CT revealed an aortic graft within a hollow viscus, suggesting an AEF.
Findings:
- The case highlights a rare instance of an aortic graft eroding into a hollow viscus.
- Aortoenteric fistula diagnosis can be challenging due to atypical presentations.
- Delayed diagnosis significantly increases the risk of fatal outcomes.
Implications:
- A high index of suspicion is essential for timely AEF diagnosis in patients with relevant surgical history.
- Prompt recognition and management of AEF are critical to prevent mortality.
- This case underscores the importance of advanced imaging in diagnosing rare surgical complications.
