Disappearance of 'pseudocholangiocarcinoma sign' in a patient with portal hypertension due to complete thrombosis of left portal vein and main portal vein web after web dilatation and transjugular intrahepatic portosystemic shunt.

摘要

The main portal vein web is probably a consequence of portal vein thrombosis, which is a very rare cause of portal hypertension. Principal manifestations are related to the degree of portal hypertension. In the literature, no data has been found for the treatment modality of portal vein web. We report, herein, the clinical and laboratory findings of a 38-year-old woman with angiographically proven incomplete main portal vein web and complete thrombotic occlusion of the left portal vein causing pseudocholangiocarcinoma sign (PCCS) on the common bile duct. She was treated by transjugular intrahepatic portosystemic shunt (TIPS) and membrane dilatation, which resulted in complete disappearance of collaterals and PCCS. It appears that TIPS and balloon dilatation of the portal vein web via transjugular approach was effective in decreasing portal pressure and its consequences.
