[Treatment of different variants of the mixed form of portal hypertension].

Among 425 patients who were under observation for portal hypertension 72 (16.9%) had its mixed form. Thrombosis of the portal vein in liver cirrhosis occurred in 6 patients. Marked hepatic fibrosis caused by obstruction of the portal vein was encountered in 14 patients. Compression of the hepatic segment of the inferior vena cava was found in 44 patients with cirrhosis of the liver. Nutmeg cirrhosis developed in 8 patients in prolonged disorder of venous flow from the liver. Coexistence of pre- and intrahepatic forms of portal hypertension occurred in the first two situations and coexistence of intra- and suprahepatic forms in the second two. The variety of mixed forms of portal hypertension should be borne in mind in choosing the method of operative treatment and defining its prognosis.
