目的:研究慢性脑供血不足的颈动脉粥样硬化特点。方法:分别对100例慢性脑供血不足患者和100例正常对照者及100例脑梗死病人行颈动脉彩色多普勒检查,测量相关指标。结果:观察组颈动脉粥样斑块发生率60%,内膜粗糙率31%,颈动脉内膜中层厚度>1.00mm者占24%,颈动脉狭窄率23%;正常对照组分别为18%,4%,4%,6%;梗死对照组分别为90%,62%,51%,45%。经统计学分析,观察组与正常对照组比较,差异显著(P<0.01),梗死对照组与观察组比较也有显著差异(P<0.01)。结论:慢性脑供血不足是动脉粥样硬化过程的一个阶段,是缺血性脑卒中的预兆。
Objective: To study the characteristics of carotid atherosclerosis in chronic cerebral insufficiency. Methods: Carotid artery color Doppler was performed on 100 patients with chronic cerebral hypoperfusion, 100 normal controls and 100 patients with cerebral infarction. The related indexes were measured. Results: The incidence of carotid atherosclerotic plaques in observation group was 60%, the intima roughness was 31%, carotid artery intima-media thickness> 1.00mm was 24% and carotid artery stenosis was 23%, while the control group was 18% , 4%, 4%, 6% respectively. The infarction control group was 90%, 62%, 51% and 45% respectively. After statistical analysis, there was significant difference between the observation group and the normal control group (P <0.01). There was also significant difference between the control group and the observation group (P <0.01). Conclusion: Insufficient chronic cerebral insufficiency is a stage of atherosclerosis and a sign of ischemic stroke.
