Traumatic superior mesenteric arteriovenous fistula. A case report

Area of Science:

• Vascular Surgery
• Trauma Surgery
• Interventional Radiology

Background:

• Traumatic arteriovenous fistulas (AVFs) can occur after abdominal injuries.
• Superior mesenteric artery (SMA) AVFs are rare but can lead to significant complications.

Observation:

• A patient presented with a superior mesenteric arteriovenous fistula secondary to a stab wound.
• Clinical presentation lacked signs of high-output cardiac failure or portal hypertension.
• Selective angiography was crucial for diagnosis and localization.

Findings:

• The AVF was successfully identified and confirmed using selective angiography.
• Surgical intervention involved resection of the aneurysm and fistula.
• A prosthetic graft was used for reconstruction.

Implications:

• This case highlights the utility of selective angiography in diagnosing rare vascular injuries.
• Prompt surgical management of SMA AVFs can lead to favorable outcomes.
• Effective treatment strategies exist for traumatic mesenteric AVFs.
