What is portal hypertension?

See below : Portal hypertension is a complication of cirrhosis. Scarring in the liver decreases venous blood flow from the intestinal veins through the liver to the heart. This leads to increased pressure in the intestinal veins. This can cause dilated veins in the esophagus (varices) which are prone to bleeding, an enlarged spleen, low platelets, and fluid accumulation in the abdomen (ascites).

Portal hypertension: This is an obstructive condition of the venous outflow from the liver, often associated with cirrhosis. It causes abdominal distension and fluid leak into the legs and abdomen.
