We studied the relationships between portal pressure measured using the portal venous pressure gradient, the development of gastroesophageal varices, and the risk of variceal bleeding in 56 patients with cirrhosis. Portal pressure was higher in patients with varices than in those without (P>0.01), and 11 mmHg was the lowest portal pressure measured in the patients with varices. The size of the varices was not associated with the portal pressure. There was no difference in the value of portal pressure measurements for the patients with variceal bleeding and those without and there was no linear‐relationship between the degree of portal hypertension and the rate of variceal bleeding. 12 mmHg was the lowest portal pressure measured in the patients with variceal bleeding. The size of the varices was related to the rate of variceal bleeding (P>0.05). We conclude that (a) a portal pressure of 11 mmHg is necessary for the formation of varices, (b) 12 mmHg of portal pressure is necessary for variceal bleeding to occur but the degree of portal hypertension has no predictive value for the risk of variceal bleeding, and (c) the size of the varices does not depend on the degree of portal hypertension but is associated with the risk of variceal bleeding.
