Summary
A rare paraprosthetic-sigmoid fistula was diagnosed in a patient after complex aortic abdominal surgery. Computed tomography imaging revealed inflammatory tissue between the aortic prosthesis and the sigmoid colon, confirming the fistula.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Radiology
Background:
- Aortic abdominal surgery can lead to rare but serious complications.
- Paraprosthetic fistulas, particularly involving the gastrointestinal tract, pose significant diagnostic and management challenges.
Observation:
- A case report details a patient who developed a paraprosthetic-sigmoid fistula.
- The fistula occurred subsequent to a complicated aortic abdominal aneurysm repair.
Findings:
- Computed tomography (CT) imaging was crucial for diagnosis.
- CT demonstrated inflammatory changes around the aortic prosthesis limb.
- The inflammatory tissue was noted in close proximity to the sigmoid colon, indicative of a fistula.
Implications:
- Early and accurate diagnosis of paraprosthetic fistulas is critical for patient outcomes.
- Multimodality imaging, such as CT, plays a key role in identifying these complex surgical complications.
- This case highlights the importance of considering rare fistulas in patients with relevant surgical history and symptoms.
