摘　　要：目的　探索部分性脾栓塞术对肝硬化门脉高压脾功能亢进病人门脉血流动力学的改变。方法　选择 2 4例肝炎后肝硬化门脉高压伴脾亢病人作部分性脾栓塞术 (PSE) ,术中动态观察其自由门脉压变化 ,PSE前后用多普勒超声观测门脉系统血管内径、血流速度的数值 ,作自身对照研究。结果　PSE后自由门脉压平均下降 3 .2± 0 .4mmHg ,平均下降 11.2 % ;门脉血流量及脾静脉血流量均下降 ,门脉血流量由 110 4ml/min降到 793ml/min ,脾静脉血流量由 897ml/min降到 35 5ml/min。Objective To evaluate the changes of hypersplenism patients with post-hepatitis cirrhosis and hypertension who treated by partal splenic embolization.Methods 24 patients with hypertension and hypersplenism were treated by PSE.In the operations we measured the free portal pressure(FPP).Before and after the operation,all patients diameter and velocity of portal veins and splenic veins were measured by Doppler ultrasonography.Results Compared with the condition before operation,the FPP decreased 3.2±0.4 mmHg,the quantity of blood flow of portal veins from 1104 ml/min dropped to 793 ml/min,and that of splenic veins from 897 ml/min dropped to 355 ml/min.Conclusion PSE can improve the state of hyperdynamic circulation of portal veins system in a little time.
