颈动脉粥样硬化斑块质地的超声评价与脑梗死相关性分析

Ultrasound in the Evaluation of the Correlation between Carotid Artery Plaque and Cerebral Infarction

目的探讨颈动脉斑块性质与脑梗死是否存在相关关系,以及超声诊断在斑块性质评估中的价值。方法经彩色多普勒超声检查发现颈动脉粥样硬化斑块并同时做头部MR I检查的患者97例,以超声表现为依据,分为稳定性斑块和不稳定性斑块两组;以MRI表现为依据,确定脑梗死,比较两组病例脑梗死发生率的差异,分析斑块质地与脑梗死的相关性。结果脑梗死的发生率颈动脉不稳定性斑块,明显高于稳定性斑块,两组差异有统计学意义(P<0.05)。logistic回归分析发现,年龄、高血压、糖尿病与脑梗死发生率相关(P<0.05),而与高脂血症无相关性(P>0.05)。结论颈动脉斑块的超声诊断及斑块质地的评估对梗死的防治有重要意义。

Objective To investigate the correlation between the characteristic of carotid artery plaque and cerebral infarction,and the value of ultrasonic diagnosis in the evaluation of plaque.Methods97 cases of carotid artery atherosclerotic plaque were found by ultrasound examination,who received MRI examination at the same time.According to ultrasonic appearance,all the patients were divided into two groups.They were instability plaques group and stability plaques group.The cerebral infarction was determined by MRI,and the incidence of cerebral infarction was compared between the two groups to analyze the relationship between the characteristic of carotid artery plaque and cerebral infarction.ResultsThe incidence of cerebral infarction of instability plaque group was significantly higher than that of stability plaques group,the difference was significant statistically（P0.05）.The correlations among age,hypertension,diabete and cerebral infarction was found（P0.05）,however,no correlation between hyperlipemia and cerebral infarction was found（P0.05）.ConclusionCarotid plaque ultrasonic diagnosis and assessment of plaque texture may play an important role in the prevention of prevention and treatment of cerebral infarction.
