[The partial portosystemic shunting and its hemodynamic consequences]

Complex hemodynamical investigations were done in 32 patients in 1985-1999 yr. period before the operation, in 6-8 and 12-24 mo after performance of the partial portosystemic shunting operation (in 8 patients mesentericocaval anastomosis was formed, in 10--central splenorenal anastomosis, in 12--splenorenal anastomosis side to side and in 2--lowermesentericorenal anastomosis). The performance of shunting operation had promoted the lowering of the blood flow volumetric velocity and of the pressure in v. cava as well, its diameter reduction, the lowering of general hepatic blood flow. The lowering of blood flow in the v. cava system after the shunting operation performance caused the arterial hepatic blood flow enhancement occurrence.
