Angiography in diagnosis and therapy of diffuse hepatocellular disease.

Angiography is of value in the diagnosis and interventional therapy of diffuse hepatocellular disease. Hepatic arteriography is the primary diagnostic method; hepatic venography, portal venography, transvenous liver biopsy and direct cholangiography are complementary. They allow the assessment of type and stage of diseases, their hemodynamic consequences and permit the differentiation of diffuse diseases from tumorous processi. Selective vasopressin infusion and transhepatic catheter obliteration of varices are interventional techniques used to control massive bleeding from gastroesophageal varices--one of the most serious complications of diffuse hepatocellular diseases.
