Modern management of portal hypertension.

摘要

The development of portal hypertension plays a major role in the pathogenesis of many of the complications of chronic liver disease. In developed countries, most patients with portal hypertension have cirrhosis, and, in this condition, portal pressure is elevated as a result of both an increase in hepatic resistance to portal perfusion and increased mesenteric blood flow. Bleeding from oesophageal varices is a major cause of mortality in patients with significant portal hypertension. This review concentrates on the recognition, prevention and acute management of this life threatening complication of cirrhosis.
