In this series, we studied about diagnostic significance of hepatic venography and retrograde portography in portal hypertension by using stepwise discriminant analysis. The accuracy rate of the discrimination was 95% in liver cirrhosis (LC), 86% in B' type LC, 83% in primary biliary cirrhosis (PBC) and 57% in idiopathic portal hypertension (IPH). The difficulty in differential diagnosis of IPH from PBC was due to similarity of hepatic vascular changes in both diseases. Next we studied about the relationship between venographic findings and the causes of LC. The size of regenerated nodule in alcoholic LC was significantly smaller than the others, so venographic findings were different from others. It was concluded that hepatic venography was useful examination for differential diagnosis in portal hypertension, and was effective for considering about the causes of LC.
