TIPS placement and recanalization of a segmental occluded main portal vein in a 26-year-old man with portal cavernoma. (a-b) CT scan shows occlusion of the portal vein at the hepatic hilum and partial patent main portal vein. (c) Portal venogram following access into the portal venous system reveals occlusion of the main portal vein and numerous collateral veins around the hilum. (d) Final portography obtained after TIPS placement with the distal end of the stent into the main portal vein demonstrates a good backflow through the shunt.
