[Isotope methods in diagnosis of portal vein occlusion].
The dynamic intravenous hepato-scintigraphy with pertechnetate Tc-99m enables a quantitative evaluation of portal and arterial blood flow in the liver. A case is presented of thrombotic occlusion of the portal vein with rapidly growing oesophageal varices in which hepato-scintigraphy showed the absence of portal blood flow in the liver, being the decisive diagnostic method. Using the dynamic transrectal porto-scintigraphy an evaluation was done of the degree of collateral circulation development in the area of the inferior mesenteric vein, obtaining indirect information about localization and duration of portal vein occlusion.
