颈动脉斑块风险分级对缺血性中风再发的预测价值

摘要

目的 探讨颈动脉硬化斑块超声图像的风险分级对缺血性中风再发的预测价值.方法 选取内科住院并接受过颈动脉超声检查的缺血性中风患者69例,进行颈动脉彩色多普勒超声检查.根据颈动脉斑块形态、回声、表面是否有溃疡或血栓等特征对斑块进行分级,随访1年后观察缺血性中风复发情况.结果 69例患者的颈动脉检查结果:单发斑块6例,双侧多发斑块63例.1年内再发缺血性中风32例,其中18例患者为双侧再发者.缺血性中风再发侧的颈动脉斑决风险分级主要为2级和3级,而未再发侧主要为1级,2组间差异有统计学意义(P＜0.05).结论 颈动脉斑块风险分级简单全面地评估了颈动脉斑块的稳定性,在预测缺血性中风再发的风险中具有重要意义,缺血性中风易患人群应重视超声对颈动脉斑块的筛查,及时对高风险的斑块进行处理.%Objective To investigate the prediction value of carotid plaques ultrasound image risk classification in predicting ischemic stroke relapse.Methods Sixty-nine patients with ischemic stroke who received carotid artery examination by color Doppler ultrasound in our hospital from March 2014 to December 2015 were enrolled in the study.According to the characteristics of morphous,echo,ulcers or thrombosis on surface of plaques,the carotid plaques were classified.The ischemic stroke relapse condition was observed after 1-year follow up.Results The carotid artery examination results showed that six patients had single plaque,63 patients had bilateral multiple plaques.Among 69 patients,there were 32 cases of ischemic stroke relapse,including 18 cases bilateral ischemic stroke relapse.The carotid artery plaque risk classification in the side of ischemic stroke relapse was mainly grade 2 and grade 3,however,which in the other side was mainly grade 1,there was a significant difference between two groups (P ＜ 0.05).Conclusion The carotid plaque risk classification is a simple and comprehensive method to evaluate the stability of carotid plaque,which plays an important role in predicting ischemic stroke relapse.
