Intrahepatic portosystemic venous shunt passing through the left inferior phrenic vein and draining into the left renal vein

Abstract

We report a case of an intrahepatic portosystemic venous shunt (IPSVS) passing through the left inferior phrenic vein and draining into the left renal vein and then to the inferior vena cava. We incidentally detected the IPSVS while performing a transcatheter arterial embolisation for the treatment of hepatocellular carcinoma. IPSVS with the left inferior phrenic vein as the draining vein is very rare. The complete pathway of this IPSVS could be clearly demonstrated by multidetector row CT during arterial portography.
