[Hemodynamic and functional changes in the liver of children with extrahepatic portal hypertension in relation to the method of portacaval shunt].

Scintihepatographic investigations with colloid 99mTc before and after operations in 4 groups of children were performed: with cavo- or ileomesenterial anastomosis, with splenorenal anastomosis with splenectomy and cavo- or ileomesenterial anastomoses in children with previously performed splenectomy and in a group of comparison. Perfusion of the liver was found to decrease: in the least degree after splenorenal anastomosis and in the greater degere after cavo- and ileomesenterial one. It was established that all kinds of shunts ensured function of hepatocytes.
