Nonselective beta-blockers eg, propranolol, nadolol, carvedilol. The initial factor in the etiology of portal hypertension is an increase in the vascular resistance to the portal blood flow. Are TIPS tops in the treatment of portal hypertension? Vasoconstriction induced by the contraction of stellate cells. Merkel C, Marin R, Enzo E, et al. Essentials of Medical Physiology. Local changes in the distal esophagus eg, gastroesophageal reflux — These have been postulated to increase the risk of variceal hemorrhage, but evidence to support this view is weak; studies indicate that gastroesophageal reflux does not initiate or play a role in esophageal hemorrhage [ 1617 ]. Medical treatment of portal hypertension.
Updating consensus in portal hypertension: Ravindra KV, Eng M, Marvin M. The superior mesenteric vein and the splenic vein unite behind the neck of the pancreas to form the portal vein. An elevated pressure difference between systemic and portal circulation ie, HVPG directly contributes to the development of varices. Hepatitis B virus—related and hepatitis C virus—related cirrhosis.

However, veno-occlusive diseases and primary biliary cirrhosis are more common in cirrhosis and in females with esophageal esophageal varices, alcoholic liver disease, viral hepatitis, veno-occlusive disease, and primary biliary cirrhosis are usually responsible. Increased hepatic vascular resistance in cirrhosis is not only a mechanical consequence liver the hepatic architectural disorder; a dynamic component also exists due to the active contraction of myofibroblasts, activated stellate cells, and vascular smooth-muscle cells of the intrahepatic veins. May indicate portal-parietal peritoneal shunting. Increased portal pressure contributes to increased varix size and decreased varix wall thickness, thus leading to increased variceal wall tension.
