摘　　要：目的　探讨各期高血压病人颅内血管血流动力学变化规律。方法　应用 (TCD)对 384例高血压病人及 5 0例正常对照组的双侧大脑中动脉 (MCA)、大脑前动脉 (ACA)、大脑后动脉 (PCA)、椎动脉 (VA)、基底动脉 (BA)的平均血流速度 (Vm)、血流脉动指数 (PI)及频谱形态进行观测。结果　高血压Ⅰ期组病人MCA、ACA的Vm升高 ,PCA、VA、BA的Vm无变化 ,PI无变化 ,频谱形态正常。Ⅱ、Ⅲ期病人颈内动脉系统、VA、BA的Vm渐降低 ,PCA无变化 ,PI升高 ,并伴有频谱形态改变。结论　TCD检查可了解高血压病人的脑血管病理生理变化 ,评价脑动脉弹性功能以及脑供血情况 。Objective: To observe the changes of cerebral hemodynamics in patients with hypertension. Methods: The Vm,PI and spectrum of MCA,ACA,PCA,VA and BA were detected in 384 patients with hyperttension and 50 cases as control group. Results: In I stage patients,the Vm increased in MCA and ACA.The Vm,PI and spectram in PCA ,VA and BA did not change.InⅡto Ⅲ stage patients, the Vm decreased in MCA,ACA,VA and BA. The PI increased and the spectrum changed. Conclusion: TCD may be used to evaluate cerebral vascular changes in patients with hypertension.
