Detailed measurement of the diameters of the venous branches on radiographs revealed an existence of morphological changes in chronic hepatitis, not only in liver cirrhosis. Relation between the types based on a peritoneoscopic classification and the manner of vascular changes was studied in accordance with the changes observed in liver cirrhosis.
