A percutaneous transjugular intrahepatic portocaval shunt (TIPS) was successfully performed using Wallstents in a 53-year-old man with neoplastic disease causing portal hypertension and life-threatening variceal hemorrhage. Shortly afterwards, recurrent hemorrhage was investigated by shunt venography which showed that extrinsic narrowing of the hepatic vein and hepatic vena cava was causing shunt thrombosis. Shunt thrombosis was cleared by balloon occlusion of the shunt and forceful retrograde flushing of thrombus into the portal circulation. The compressed hepatic vein and vena cava were then dilated and stented using Gianturco "Z" stents. Bleeding recurred 3 months later due to focal narrowing within the shunt which possibly was due to intimal proliferation. Repeat dilatation and placement of a coaxial Palmaz stent again relieved portal hypertension. Creation of a TIPS for portal hypertension secondary to neoplasm can produce valuable palliation. Complete assessment of hepatic vein and vena cava patency is required to ensure shunt function.
