摘要
目的 :探讨肝硬化门脉高 (PTH)的血流动力学变化及其与血中AT Ⅱ的关系。方法 :4 8例肝硬化PTH患者 (代偿期 18例、失代偿期 30例 )及 32例正常人作为研究对象 ,应用双功能多普勒测定门、脾静脉血流量 (PVBF&SVBF) ,同步测定血中AT Ⅱ的水平 ,并分析PVBF&SVBF与AT Ⅱ的相关性。结果 :门脉系统高血流动力学改变存在于肝硬化PTH发病的始终 ,代偿期显著下降的AT Ⅱ与门脉高血流动力学变化无相关性 ,失代偿期显著升高的AT Ⅱ与门脉高血流动力变化呈正相关。结论 :此研究对临床诊治有指导意义。
Objective:To study the relationships of portal hypertensions to vasoactive substances-angiotensin(AT-Ⅱ)in cirrhosis patients.Methods:48 patients with liver cirrhosis(LC)(including 18 patients with compensated LC and 30 patients with decompensated LC) and 32 normal controls(NC) were studied. Color duplex doppler ultrasonography was used to study portal venous and splenic venous blood flow(PVBF and SVBF).Also,the blood concentration of AT-Ⅱ was detected.Then,analyze the correlation between PVBF and SVBF to AT-Ⅱ.Results:Portal hyperdynamic exists in cirrhosis patients from beginning to the end. Low level of AT-Ⅱ in compensated LC patient has no relation with portal hyperdynamic, high level of AT-Ⅱ in decompensated LC has positive relation with portal hyperdynamic.Conclusion:This study has directed significance of clinical treatment and diagnosis.
