Demonstration of portosystemic shunts by radionuclide venogram.
In two patients with inferior vena caval obstruction, radionuclide venography using 99mTc-macroaggregated albumin demonstrated diffuse radioactivity in the liver, indicating portosystemic shunts. Follow-up venography after anticoagulation therapy showed disappearance of the hepatic activity in one patient.
