目的通过对颈动脉粥样硬化的检测,研究其与脑梗死的相关性。方法对MRI的弥散加权成像(DWI)证实的60例急性期脑梗死患者(脑梗死组)和60例非脑血管病患者(对照组),采用彩色多普勒超声方法分析患者颈动脉斑块的分布、形态、数量和回声特征。结果脑梗死组颈动脉内膜、中膜厚度、斑块、狭窄程度及斑块性质与非脑血管病组比较差异有统计学意义(P<0.01),斑块检出率差异有统计学意义(P<0.05)。结论颈动脉粥样硬化是脑梗死的重要危险因素,对其进行干预性治疗可减少脑梗死的发生。
Objective To study the relationship between carotid atherosclerosis and cerebral infarction. Methods Sixty patients with acute cerebral infarction (cerebral infarction group) and 60 patients with non-cerebrovascular disease (control group) confirmed by DWI were analyzed with color Doppler ultrasonography in patients with carotid plaque The distribution, morphology, quantity and echo characteristics. Results The carotid artery intima-media thickness, plaque, stenosis and plaque quality in the infarction group were significantly different from those in the non-cerebrovascular disease group (P <0.01), and the difference of the plaque detection rate was statistically significant (P <0.05). Conclusion Carotid atherosclerosis is an important risk factor for cerebral infarction. Interventional therapy can reduce the incidence of cerebral infarction.
