Multidetector CT findings of right intrahepatic portosystemic venous shunt

Abstract

Purpose To evaluate multidetector CT features of right intrahepatic portosystemic venous shunt (IPSVS). Materials and Methods Pathways of right IPSVS were evaluated from 20 patients. Diameters of right portal veins were measured in IPSVS patients, 30 cirrhotic and 30 healthy patients. Result Among 22 IPSVSs, shunt between posterior branch and inferior phrenic vein was most common. Diameters of the posterior branch were larger in IPSVS patients than in other groups. Conclusion Most right IPSVSs drain to inferior phrenic vein through dilated posterior branch.
