彩色多普勒超声对颈动脉粥样硬化与脑梗死的相关性分析

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。

Correlation study of carotid artery atherosclerosis and cerebral infarction by color ultrasonography

Objective To evaluate the relationship between carotid artery atheroselerosis and cerebral infarction. Methods Carotid artery intima-media thickness （IMT）, plaque detection rate and diameter straightness were measured in 82 patients with cerebral infarction and compared with 46 patients without cerebral infarction by two-dimension and color Doppler ultrasonography. A characteristic of plaque was observed. Results Carotid artery IMT and plaque detection rate and the degree of carotid artery diameter straitens were more increased among cerebral infarction compared with the control groups, there was significant difference between the both group （P〈0.01）. The rate of plaque in cerebral infarction group （58/82,70.7%） was higher than that of control group （15/46,32.6%）. The IMT of CCA of cerebral infarction group （1.38＋0.14） was higher than the control group （0.89~0.16）. The IMT of ICA of cerebral infarction group （1.16＋0.27） was higher than the control group （0.78~ 0.17）. Ulcerous plaque and soft plaque among cerebral infarction was more than others. Carotid plaques happens at bifurcation place （44.4%）, soft plaque and ulcerous plaque（59.2%）. Conclusions Degree of carotid artery atherosclerosis and occurrence of cerebral infarction has close relationship. Evaluation the degree of carotid artery atherosclerosis using doppler uhrasonography early has an important clinical value in prevention and treatment of cerebral infarction.
