[Radioisotope study of portal blood flow in extrahepatic portal hypertension in children].
The volume of portal blood that goes through the liver in portal hypertension is unknown up today. The level of portal perfusion after distal splenorenal bypass creation is not known either. Radioisotope splenography and mesenteriocoportography have been used to measure this level. It was found that in half of children with EPH more that 50% of the splenic blood and 100% of the blood from the superior mesenteric vein passes through the liver. The creation of the distal splenorenal bypass provided the perfusion at the level between 32 and 100% from the starting point. 100% of portal blood will pass to lungs through the bypass after traditional bypass operations.
