超声检测颈动脉粥样硬化对复发性脑梗死的预测价值

The value of carotid artery atherosclerosis in predicting recurrent cerebral infarction by color Doppler ultrasound

目的探讨彩色多普勒超声检测脑梗死患者颈动脉粥样硬化对预测复发性脑梗死的诊断价值。方法彩色多普勒超声检测105例脑梗死患者（复发性脑梗死58例，初发性脑梗死47例）及52例健康人为对照组的颈动脉内中膜厚度及斑块形成情况，并对斑块进行分级。结果与初发性脑梗死组和对照组比较，复发性脑梗死患者颈动脉内中膜厚度及斑块检出率增高，软斑及溃疡斑数目增多，3级斑块例数增多（P〈0．05）。复发性脑梗死的预测模型显示：有斑块患者患复发性脑梗死的概率是无斑块患者的2．46倍，斑块分级高患者患复发性脑梗死的概率是斑块分级低患者的11．86倍。结论超声能有效检测脑梗死患者颈动脉管壁及管腔的变化，为临床预报复发性脑梗死提供有价值的信息。

Objective To explore the diagnostic value of carotid artery atherosclerosis plaque in predicting recurrent cerebral infarction by color Doppler ultrasound. Methods The carotid arteries itima - media thickness（IMT） and development of carotid arteries plaque in 105 patients with cerebral infarction（58 recurrent patients ,47 initial patients） and 52 normal patients were measured by color Doppler ultrasound, then the carotid arteries plaques were ranked. Results The IMT and carotid artery atherosclerosis plaques in patients with recurrent cerebral infarction were higher than those in initial group and control group, and numbers of soft plaque and ulcer plaque in recurrent group were increased obviously. The predicting model of recurrent cerebral infarction showed that the death rate of patients with recurrent cerebral infarction was 2.46 times than that of nomal patients, and the death rate of patients with higher rank was 11.86 times than that of the lower rank patients. Conclusion Color Doppler ultrasound can detect carotid wall and lumen changes of patients with cerebral infarction effectively, and also can provide valuable information about recurrent cerebral infarction for clinical prediction.
