Portal hypertension is caused by distortion of the hepatic architecture which leads to an increased resistance to portal blood flow and eventually an increase in portal venous pressure. Less commonly, portal hypertension may result from increased portal blood flow. Normal portal venous pressure ranges from 6 to 8mmHg. In portal hypertension, portal vein pressure rises to greater than 12mmHg (averaging 20mmHg), and sometimes exceeds 50–60mmHg. Portal hypertension is classified into prehepatic, intrahepatic, and posthepatic causes. (Table 55.1)
