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. [ABSTRACT FROM AUTHOR]
