Summary
A rare aortoesophageal fistula formed between the esophagus and a descending thoracic aorta aneurysm two weeks post-surgery. Computed tomography imaging confirmed the fistula after contrast material ingestion.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Radiology
Background:
- Aortoesophageal fistulas are rare but life-threatening complications.
- Graft replacement of the descending thoracic aorta is a complex procedure.
- Post-operative complications can arise, necessitating prompt diagnosis.
Observation:
- An unusual aortoesophageal fistula developed.
- The fistula formed between the midthoracic esophagus and the residual aneurysm wall.
Findings:
- This complication occurred two weeks after descending thoracic aorta graft replacement.
- A computed tomography (CT) scan with water-soluble contrast confirmed the aortoesophageal fistula.
Implications:
- Highlights a rare but serious post-operative complication following thoracic aortic aneurysm repair.
- Emphasizes the importance of advanced imaging in diagnosing complex fistulas.
- Informs surgical strategies and post-operative care protocols for thoracic aortic surgery.
