目的探讨颈动脉彩超检查在老年脑梗死患者粥样斑块诊断中的应用价值。方法对42例无脑梗死老年人(对照组)和48例老年脑梗死患者(梗死组)的颈动脉内中膜厚度(IMT)采取彩超多普勒超声及斑块类型和斑块形态进行检查。结果老年脑梗死组的36例颈动脉具有不同程度大小的粥样硬化斑块,其发生率高达75.00%。对照组中也发现10例不同程度的粥样硬化斑块,发生率达23.81%,对照组颈和梗死组动脉IMT分别是(0.31±1.22)mm、(0.16±0.68)mm,两组间比较,差异具有统计意义(P<0.05)。结论颈动脉粥样斑块和脑梗死有着密切的关系。颈动脉彩超检查老年脑梗死患者的颈动脉粥样硬化斑块具有很好的诊断价值,在预防和诊断老年脑梗死的发展具有重要意义。
Objective To investigate the value of carotid ultrasonography in the diagnosis of atherosclerotic plaques in elderly patients with cerebral infarction. Methods The carotid intima-media thickness (IMT) in 42 elderly patients without cerebral infarction (control group) and 48 elderly patients with cerebral infarction (infarction group) were examined by color Doppler ultrasonography and plaque type and plaque morphology . Results 36 cases of carotid artery in elderly patients with cerebral infarction with varying degrees of atherosclerotic plaques, the incidence of up to 75.00%. Ten cases of atherosclerotic plaque were found in the control group, with a rate of 23.81%. The IMT of the neck and infarction group in the control group were (0.31 ± 1.22) mm and (0.16 ± 0.68) mm, respectively , The difference was statistically significant (P <0.05). Conclusion There is a close relationship between carotid artery plaque and cerebral infarction. Carotid ultrasound examination of carotid atherosclerosis plaque in elderly patients with cerebral infarction has a good diagnostic value, in the prevention and diagnosis of cerebral infarction in elderly patients is of great significance.
