Abstract
Techniques of hepatic vein catheterization, hepatic venous pressure measurement, and occlusion phlebography using a balloon catheter are described. Hepatic venous pressure measurements (n=95) and hepatic occlusion phlebography were combined in 32 cases. In patients with liver cirrhosis (n-63) a significant elevation of hepatic venous pressure gradients was found. A decrease of the pressure gradient was seen after portacaval and splenorenal shunt operations. Hepatic occlusion phlebography showed alterations of hepatic veins only in patients with cirrhosis. A rough correlation between pressure gradients and the extent of changes in the liver veins was found. Hepatic occlusion phlebography, in patients who had undergone shunt procedure, demonstrated various collaterals. Combined hepatic vein pressure measurements and hepatic occlusion phlebography using a balloon catheter are proposed as a very suitable method for the evaluation of chronic liver disease and portal hypertension.
