Porto-systemic collaterals in cirrhosis of the liver. Selective percutaneous transhepatic catheterization of the portal venous system in portal hypertension.Acta Radiol Diagn (Stockh). 1979; 20(6):865-77.AR
In 93 patients with cirrhosis of the liver and portal venous hypertension the main tributaries of the portal vein were examined by percutaneous transhepatic catheterization. The appearance and degree of porto-systemic collaterals were analysed. Esophageal varices were demonstrated in 82 patients. No correlation was found between the portal venous pressure and the extent of porto-systemic communications.
