Successful Coil Embolization of Congenital Intrahepatic Portosystemic Venous Shunt using Double Microcatheter Single Vascular Access Technique: A Case Report

Abstract

We report the case of a woman in her 40s with an asymptomatic, congenital intrahepatic portosystemic venous shunt diagnosed during a routine examination for uterine cervical cancer. Contrast-enhanced computed tomography (CT) and superior mesenteric arterial portography showed a complex intrahepatic portosystemic venous shunt with concomitant portal vein aneurysm near the hepatic hilum. The shunt appeared likely to be difficult to occlude via the usual endovascular procedure because the shunt point was narrow and short. Therefore, we performed coil embolization using a double microcatheter single vascular access technique and successfully treated without any complications.
