Primary aortoenteric fistula (PAEF) causes severe gastrointestinal bleeding, often preceded by "herald bleeding." Early diagnosis and surgical intervention are vital for patient survival.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Diagnostic Imaging
Background:
- Primary aortoenteric fistula (PAEF) is a rare condition.
- It presents as a significant cause of gastrointestinal hemorrhage.
- Prompt diagnosis and management are critical for patient outcomes.
Observation:
- A 55-year-old male presented with upper gastrointestinal bleeding.
- Initial endoscopic evaluations were inconclusive.
- Exploratory laparotomy was performed for diagnosis and treatment.
Findings:
- The patient was diagnosed with PAEF.
- Surgical intervention led to an uneventful postoperative recovery.
- Negative endoscopy in the context of GI bleeding can suggest PAEF.
Implications:
- A high index of suspicion is essential for diagnosing PAEF.
- Early diagnosis and swift surgical intervention improve survival rates.
- Endovascular repair presents a viable alternative treatment option.
