Endovascular repair of traumatic superior mesenteric artery to splenic vein fistula.

Traumatic mesenteric arterioportal fistulas (APF) are rare but serious and life-threatening. This article reports the case of a 24-year-old female who suffered a gunshot wound to the abdomen and subsequently developed a superior mesenteric artery (SMA) pseudoaneurysm and APF, which caused secondary right heart failure and pulmonary hypertension. The patient underwent a successful endovascular stent-graft exclusion of the pseudoaneurysm/APF. The patient was asymptomatic 18 months post procedure and leading an active life with a normal arterial flow in the SMA confirmed by duplex ultrasonography.
