[Characteristics of the reconstruction of collateral pathways after surgical decompression of the portal system].
In 20 mongrel dogs after a preliminary stenosis of the portal vein, formation of the spleno-renal or mesenteric-caval anastomosis has been performed. For revealing the vessels vital portography, injection of roentgenopaque masses and morphometry have been carried out. The spleno-renal anastomosis ensures a selective outflow of blood from the esophago-gastro-splenic zone. The collaterals, developing as a result of the porto-caval anastomoses with the anterior vena cava, and the collaterals, developing as a results of the porto-portal anastomoses, disappear. The mesenteric-caval anastomoses favourably affects the intestinal hemodynamics. The bypasses of the blood stream, developed between the portal vein and posterior vena cava reduce predominantly. The decompressive angioanastomoses result in local hypertension in the posterior vena cava system.
