NON-CIRRHOTIC PORTAL FIBROSIS CAUSING PORTAL HYPERTENSION

Abstract

Portal hypertension is more prevalent in patients with liver cirrhosis and occurs infrequently in those without liver cirrhosis. Non-cirrhotic portal brosis (NCPF) and extrahepatic portal venous obstruction (EHPVO) are the two most common causes of non-cirrhotic portal hypertension. Unlike EHPVO, NCPF does not cause thrombosis of the extrahepatic portal vein. Sclerosis of the portal vein's medium and small branches occurs in NCPF. In NCPF, the hepatic venous pressure gradient (HVPG) is normal, in contrast to cirrhosis, where it is increased. Additionally, NCPF is referred to as non-cirrhotic intrahepatic portal hypertension (NCIPH), idiopathic portal hypertension, hepatoportal sclerosis, and benign intrahepatic portal hypertension. It is a disease with an unknown etiology that primarily affects middle-aged males and females and manifests as hematemesis and massive splenomegaly
