title: [Attempt to use partial occlusion of the spleen in extrahepatic portal hypertension in children].
abstract: Hemodynamics in the portal system was assessed at digital subtraction angiography in 57 children aged 9 months-15 years suffering from extrahepatic portal hypertension. Natural splenorenal anastomoses were found in 31 patients. 13 patients developed arteriovenous shunting into gastroesophageal plexus through the conglomerate of pathological vessels in the upper splenic pole. Partial occlusion of the spleen was performed in 12 patients aged 3-12 to block arteriovenous anastomoses and to reduce the blood flow from the spleen to the portal system. In various postocclusion periods blood effusion into gastric veins through arteriovenous shunts and retrograde flow via splenic vein and natural splenorenal anastomoses to the lower vena cava inferior were absent or drastically diminished. Septic complications were absent. Partial splenic occlusion in children with extrahepatic portal hypertension is considered valid.
