目的:探讨脑梗塞病人与正常人颈动脉、椎动脉之间的各种病变和血流动力学关系。方法:彩色多普勒检测35例脑梗塞病人,42例年龄相当正常人颈动脉、椎动脉。结果:梗塞组内径明显增宽,内膜增厚;舒张期流速及平均流速降低;收缩期峰值流速无明显差异;搏动指数、阻力指数增高;管腔内斑块发生率高。结论:彩色多普勒能反映脑梗塞后血管的顺应性、弹性;评价血管收缩、舒张功能和阻力状况,从而在病变早期为临床提供信息。
Objective: To investigate the relationship between various diseases and hemodynamics of carotid and vertebral arteries in patients with cerebral infarction. Methods: 35 cases of cerebral infarction were detected by color Doppler, and 42 cases of carotid artery and vertebral artery of quite normal age. Results: The inner diameter of the infarction group was obviously widened and the intima was thickened. The diastolic flow velocity and average flow velocity were decreased. There was no significant difference in the peak systolic velocity. The pulsatility index and resistance index were increased. The incidence of intraluminal plaque was high. CONCLUSION: Color Doppler can reflect the compliance and flexibility of blood vessels after cerebral infarction. Evaluate the vasoconstriction, diastolic function and resistance status so as to provide clinical information in the early stages of the disease.
