Post-traumatic superior mesenteric arteriovenous fistula: Endovascular treatment with a covered stent

This case report concerns a patient who sustained multiple stab wounds causing rupture of the liver, duodenum, stomach, and pancreas. Two months after the initial injuries were repaired, the patient complained of persistent epigastric pain, vomiting, and nausea, with marked deterioration of his clinical condition. Computed tomography showed early enhancement and enlargement of the superior mesenteric vein, and selective angiography demonstrated a fistula between the superior mesenteric artery and vein. A covered stent was placed into the superior mesenteric artery, with complete closure of the fistula. The patient was discharged with complete resolution of the symptoms and full general physical recovery after stent placement.
