颈动脉易损斑块MRI表现与缺血性脑卒中的风险预测

MRI appearances of carotid vulnerable plaques and prediction of the risk of ischemic stroke

目的应用磁共振高分辨率成像技术,探讨颈动脉易损斑块MR表现与缺血性脑卒中风险预测。材料与方法经B超检查筛选颈动脉斑块并行颈部血管磁共振检查的200例老年患者,颈动脉斑块分稳定斑块组和易损斑块组,分析两组斑块成分(脂质核团,脂质坏死核心,斑块内出血,钙化,纤维帽是否破裂)及管腔狭窄程度,随访60 d内发生缺血性脑卒中的患者。结果稳定斑块组112例,60 d内发生缺血性脑卒中的患者2例;易损斑块组88例,60 d内发生缺血性脑卒中26例。结论颈动脉易损斑块与60 d内发生缺血性脑卒中有显著相关性,可以作为颈动脉狭窄患者近期临床症状的预测指标。

Objective： To study the correlation between the MRI appearances of carotid vulnerable plaque and the risk of ischemic stroke by application of magnetic resonance imaging in high resolution imaging. Materials and Methods： Two hundred cases of carotid plaques were screened by B ultrasound examination and were performed Cervical vascular magnetic resonance imaging. Carotid plaques were divided into stable plaque group and vulnerable plaque group, then we analysed the plaque composition and the degree of luminal stenosis. Patients were followed up for 60 days with the occurrence of ischemic stroke. Results： Stable plaque group 112 cases, 2 cases of ischemic stroke occurred within 60 days. Vulnerable plaque group 88 cases, 26 cases of ischemic stroke occurred within 60 days. Conclusions： There was a significant correlation between carotid vulnerable plaque and ischemic stroke within60 days. Carotid vulnerable plaque can be used as a predictor of short-term clinical symptoms in patients with carotid artery stenosis.
