Portal vein thrombosis secondary to embolization of superior mesenteric arteriovenous fistula

Ann Vasc Surg. 2014 Feb;28(2):490.e9-12. doi: 10.1016/j.avsg.2013.03.017. Epub 2013 Nov 5.

Abstract

Superior mesenteric arteriovenous fistula is a rare vascular disorder. Endovascular embolization has been widely used to treat this disease. Patients receiving successful fistula embolization generally have good prognoses. We present a man with iatrogenic superior mesenteric arteriovenous fistula who received endovascular embolization. Portal thrombus was detected on postoperative day 2, and the patient eventually died of multiple organ failure on postoperative day 13 despite having received antithrombotic and antiplatelet therapy. We identified portal thrombosis as a serious complication of transcatheter superior mesenteric arteriovenous fistula embolization.
