Multidetector CT findings of right intrahepatic portosystemic venous shunt

PurposeTo evaluate multidetector CT features of right intrahepatic portosystemic venous shunt (IPSVS).Materials and MethodsPathways of right IPSVS were evaluated from 20 patients. Diameters of right portal veins were measured in IPSVS patients, 30 cirrhotic and 30 healthy patients.ResultAmong 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.ConclusionMost right IPSVSs drain to inferior phrenic vein through dilated posterior branch.
