Portal hypertension is characterized by an increase in portal pressure (> 10 mm Hg), and could be a result of cirrhosis of the liver or noncirrhotic diseases. Noncirrhotic portal hypertension (HCPH), as it generally is termed, is a heterogeneous group of disease that is due to intrahepatic or extrahepatic etiologies. In general, the lesions in HCPH are vascular in nature and can be classified based on the site of resistance to blood flow as "prehepatic", "hepatic", and "posthepatic". The "hepatic" causes of HCPH can be subdivided into "presinusoidal", "sinusoidal", and postsinusoidal".
