Comparison of splenoportography and transhepatic portography in the diagnosis of portal vein thrombosis.
Accurate diagnosis and localization of thrombosis in the portal venous system is essential for proper surgical treatment. We compared the results of percutaneous transhepatic portography and splenoportography in 66 patients with cirrhosis of the liver. The two methods agreed on absence of thrombosis in 48, and in presence of thrombosis (verified later by surgery/autopsy) in four patients. In 12 patients an apparent thrombosis diagnosed by splenoportography was disproved by transhepatic portography, and vice versa in two patients. Free portal pressure and splenic pulp pressure did not differ significantly irrespective of the 'diagnosis' of thrombosis. We conclude, that transhepatic portography is better than splenoportography in making the diagnosis of thrombosis in the portal venous system although failure to visualize the splenic vein may indicate splenoportography.
