A fifty-two year old man with bleeding esophageal varices secondary to portal hypertension but without evidence of intrahepatic or extrahepatic obstruction is presented. Although there was no arteriovenous fistula found, there was indirect evidence that in this case the portal hypertension was secondary to increased portal flow. He was treated successfully by portacaval anastomosis.A discussion of the pathology of the liver with increased portal flow is presented.
