脑微出血与颈动脉粥样硬化相关性分析

目的探讨脑微出血与颈动脉粥样硬化的关系。方法以B超检测颈动脉,按动脉粥样硬化程度将患者分为颈动脉正常组(正常组)78例、颈动脉内中膜增厚组(增厚组)46例、斑块组36例,共3组,各组同时作头部核磁共振MRI,常规行自旋回波T1和T2加权轴位扫描,梯度回波T2加权采用Flash序列,了解有无脑微出血。结果颈动脉正常组、增厚组、斑块组脑微出血发生分别为12、16、21例。脑微出血发生在颈动脉内中膜增厚组(增厚组)和斑块组较颈动脉正常组增高(P<0.05)。结论脑微出血与颈动脉粥样硬化程度呈正相关,检测颈动脉B超对预测脑微出血有重要意义。

Objective To investigate the relationship between Cerebal microbleeds as well as carotid atherosclerosis. Methods According to carotid artery color Doppler ultrasound, 160 patients were classified into normal earotidartery（CA） group（78 patients）, intimal- medialthickness（IMT） group （46 patients） and carotid atherosclerotic plaque（CAP） group（36 patients）. Conventional and gradient echo T2 weighted MRI were performed, The patients of asymptomatic microbleeds were evaluated. Resusts The number of microbleeds were significantly greater in patients with intimal - medialthickness（IMT） group （16） and carotid atherosclerotie plaque（CAP） group（21 ）, compared with normal carotidartery（CA） group（12）, P 〈 0.05. Conclusion Color Doppler ulrasound has its clinical signifieance when aPPlied on carotid artery for Dredictinz eerebal mierobleeds.
