摘要
目的:评价老年人颈动脉彩色多普勒超声检查的临床意义,并探讨老年人脑梗死与颈动脉粥样硬化的关系。方法:回顾性分析了174例老年人颈动脉彩色多普勒超声检查结果,包括颈动脉内膜一中膜厚度(IMT)、颈动脉粥样硬化斑块、颈动脉狭窄程度及血流动力学参数。并将入选对象分为有传统危险因素的脑梗死组(A组)、有危险因素非脑梗死组(B组)和无危险因素无脑梗死组(C组)进行对照研究。结果:A组颈动脉IMT增厚、斑块积分、复合斑、舒张末期峰值流速与B组和C组相比差异有统计学意义(P<0.05)。结论:IMT厚度的增加、斑块的检出率及形态学特征、舒张末期血流速度的降低等是颈动脉病变与脑梗死发生的有意义的检测指标,在脑梗死的防治中是参考意义较大的超声学指标。
Objective: To evaluate the clinical significance of Color Doppler uhrasonography performes on elder patients with cerebral infarction, and attempt to screen out the indexes of carotid lesions related to cerebral infarction. Methods: Color Doppler ultrasonography was applied to 69 eases of cerebral infarction group of aged people with risk factors of carotid atherosclerosis; and 56 cases of non-cerebral infarction group of aged people with risk factors of carotid atherosclerosis, and 49 cases of aged people neither with cerebral infarction or risk factors of carotid atherosclerosis. The outcomes of the intima-media thickness(IMT), the atherosclerotic plaque, the degree of stenesis, and the index of change in the blood flow status of bilateral internal carotid arteres were retrospectively analyzed. Results: The IMT of common carotid arteries, the plaque scores, the detection rate of carotid plaque and the rate of compound plaques in the A group were significantly higher than those in the A and B group. The end diastolic velocities in the internal carotid arteries were lower in the A group than in the A and B group(P〈0.05). Conclusion: The IMT, the detection rate and characteristic morphology of plaques, the low end diastolic velocity were valuable indexes of carotid artery artherosclerosis related to cerebral infarction.
