Treatment of superior mesenteric artery portal vein fistula with balloon-expandable stent graft.
Visceral artery to portal vein arteriovenous fistulas are rare and difficult to treat. Covered stents have made treatment of pseudoaneurysms and arteriovenous fistulas feasible utilizing minimally invasive techniques. We present a case of a 46-year-old male with a remote history of an exploratory laparotomy after a motorcycle accident who presented with abdominal pain, malaise, and jaundice. A computed tomographic scan revealed a superior mesenteric artery to portal vein arteriovenous fistula. A large arteriovenous fistula was confirmed by arteriography. A balloon-expandable stent graft was placed across the arteriovenous fistula in the superior mesenteric artery. Postprocedure, the patient's abdominal pain resolved and his bilirubin decreased from 2.9 to 0.4. Endovascular repair of a superior mesenteric to portal arteriovenous fistula utilizing a stent graft is feasible and minimally invasive.
