[Sequential hepato-splenic scintigraphy with 99mTc-pertechnetate in experimental post-hepatic block (author's transl)].

Using baloon catheters in the inferior vena cava, post-hepatic blocks were produced in experimental animals. Subsequent liver perfusion scintigraphy showed marked reduction in portal flow. The significance of these findings in the diagnosis of the Budd-Chiari syndrome and its differentiation by scintigraphy from an intrahepatic block in cirrhosis of the liver is discussed.
