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.
对57例年龄在9个月至15岁的肝外门静脉高压患儿进行数字减影血管造影,评估门静脉系统的血流动力学。31例患者发现自然脾肾吻合。13例患者通过脾上极的病理血管团形成动静脉分流进入胃食管丛。对12例年龄在3至12岁的患者进行部分脾栓塞,以阻断动静脉吻合,减少脾脏向门静脉系统的血流。在不同的栓塞后时期,通过动静脉分流进入胃静脉的血液渗出以及经脾静脉和自然脾肾吻合逆行至下腔静脉的血流均未出现或显著减少。未发生感染性并发症。肝外门静脉高压患儿的部分脾栓塞被认为是有效的。
