Traditionally, the presence of occlusive portal vein thrombosis (PVT) is a negative clinical prognostic factor for liver cirrhosis [1,2]. This is primarily attributed to the following considerations: 1) PVT elevates the portal pressure, thereby potentially inducing portal hypertension-related bleeding events, and even death; and 2) occlusive PVT increases the technical difficulty of transjugular intrahepatic portosystemic shunt and liver transplantation.
