目的探讨颈动脉粥样硬化与脑梗死的关系。方法应用彩色多普勒超声检测82例脑梗死患者和46例非脑梗死患者颈动脉内-中膜厚度(intima-media thickness,IMT)、斑块检出率、管腔狭窄率,并观察斑块性质。结果脑梗死组斑块检出率及颈动脉内膜厚度较对照组明显增加,两组比较差异有统计学意义(P<0.01),脑梗死组斑块检出率(70.7%)明显高于对照组(32.6%);脑梗死组颈总动脉(CCA)内膜厚度(1.38±0.14)明显高于对照组(0.89±0.16),脑梗死组颈内动脉(ICA)内膜厚度(1.16±0.27)明显高于对照组(0.78±0.17)。斑块多发生于颈动脉分叉处(44.4%),以软斑块、溃疡斑块(59.2%)居多。结论颈动脉粥样硬化程度与脑梗死的发病关系密切,彩超评估颈动脉粥样硬化程度,对脑梗死的早期预防和治疗具有重要的临床价值。
Objective To investigate the relationship between carotid atherosclerosis and cerebral infarction. Methods The color Doppler echocardiography was used to detect carotid artery intima-media thickness (IMT), plaque detection rate and stenosis rate in 82 patients with cerebral infarction and 46 patients with non-cerebral infarction. Block nature. Results The detection rate of plaque and carotid intima-media thickness in cerebral infarction group were significantly higher than those in control group (P <0.01). The detection rate of plaque in cerebral infarction group (70.7%) was significantly higher than that in control group In control group (32.6%), intima-media thickness (1.38 ± 0.14) in CCA group was significantly higher than that in control group (0.89 ± 0.16), intima-media thickness 0.27) was significantly higher than the control group (0.78 ± 0.17). Plaques occurred in the carotid bifurcation (44.4%), with soft plaque, ulcer plaque (59.2%) mostly. Conclusion The degree of carotid atherosclerosis is closely related to the incidence of cerebral infarction. To evaluate the extent of carotid atherosclerosis by color Doppler ultrasonography has important clinical value in the early prevention and treatment of cerebral infarction.
