Seven patients with inferior vena-caval obstruction associated with cirrhosis of the liver are described. Inferior vena-caval obstruction is suggested when an enlarged azygous vein is seen on chest radiography, or when superficial collateral veins draining upwards are visible on the abdomen and chest. When a short obstruction or 'web' is present, this should be treated surgically. Venous thrombosis below the obstruction may result in occlusion of a long segment of the vena cava. Chronic suprahepatic venous obstruction may cause macronodular cirrhosis and predispose to the development of hepatocellular carcinoma.
