RESUMO
Non-cirrhotic portal hypertension(NCPH)is a group of diseases that show evidences of portal hypertension but no cirrhosis is present.Common causes of NCPH include pre-sinusoidal portal lesions such as portal vein thrombosis,congenital liver fibrosis and idiopathic portal hypertension,and post-sinusoidal portal lesions.The major feature of this group of diseases is well preserved liver function in spite of prominent portal hypertensive manifestations such as esophageal varices/gastrointestinal bleeding and splenomegaly/hypersplenism.Careful differentiation from cirrhosis requires thorough clinical,radiological and pathological investigation.Preventing and control of variceal bleeding and hypersplenism through medical,endoscopic and interventional procedures yield good prognosis in most of the patients with NCPH.
