| 目的 探讨正常人的肝动脉及其分支的血流动力学特点。方法 应用彩色多普勒超声对30 例正常人肝动脉及其分支,包括第一肝门处肝动脉主干( HA1) 、门静脉左支矢状切面处的左肝动脉( HA2) 、右肝动脉近末梢支( HA3) 的血流进行多普勒频谱分析,观察搏动指数(PI) 、阻力指数(RI) 、收缩期峰值流速( PSV) 、平均流速(Vm) 和舒张末流速( EDV) 。结果 正常人HA1 及其HA2 超声显示率100 % , HA3 显示率为80 %(24/ 30) 。各级肝动脉的PI (搏动指数) 和RI (阻力指数) 无明显统计学差异,而各级肝动脉的流速(包括PSV、Vm、EDV) 自主干向分支递减,各组间存在明显统计学差异。结论 影响肝动脉的彩色多普勒显示率和频谱参数的因素较多,超声医师必须熟悉解剖,掌握操作技巧和彩色多普勒技术,寻找合适的检查部位。 |

| Objective To investigate hemodynamic changes of the hepatic artery and it s branches in healthy subjects in order to provide basic data for diagnosing cirrhosis , and follow up hepatic arterial blood flow in patients with liver t ransplantation. Methods The hepatic artery and it sbranches , including HA1 , HA2 , HA3 , were assessed with color Dopplerult rasound in 30 controls , and parameters including pulsatility index ( PI) , resistance index (RI) , peak systolic velocity ( PSV) ,diastolic velocity ( EDV) and mean velocity (Vm) were measured. Results HA1 and HA2 were detected in all the patient s(100 %) , but HA3 was only detected in 24 patients (80 %) . There were significant differences of flow velocities betweengroup s , which included : PSV , EDV , Vm , but no significant differences in PI and RI were found between groups. Conclusion Color Doppler ult rasound provides a noninvasive and convenient measurement of hepatic artery and it sbranches. However , results of Doppler measurement s and detectability can be influenced by many factors. So that it is important forult rasound performers to familiar with anatomy , scan skills and color Doppler technology. |
