title: Liver tissue perfusion: comparison of radiologic and isotope clearance techniques in a patient with portal hypertension.
abstract: A patient with portal hypertension was investigated preoperatively with splenoportography and found to have a large extrahepatic shunt through esophageal varices but poor portal perfusion of the liver. However, intraoperative measurement of the hepatic tissue perfusion using the krypton-85 clearance technique showed it to be essentially normal. Erroneous conclusions about actual hepatic perfusion may be made on the basis of findings on splenoportography alone.
