title: The portal pressure-blood volume relationship in cirrhosis.
abstract: Portal pressure-blood volume curves were derived in 13 cirrhotic patients with portal hypertension and oesophageal or gastric varices by measuring portal pressure at two levels of blood volume. Portal pressure varied directly with blood volume. In seven patients where portal pressure was measured at three levels of blood volume separated by 500 ml or more the portal pressure-blood volume relationship was found to be approximately linear.
