目的 探讨脑梗死(CI)患者采取磁共振血管造影(MRA)诊断颅内动脉硬化程度的效果. 方法 将我院2012年1月至2014年1月接诊的CI患者112例作为研究对象,皆采取MRA进行诊断,诊断后的CI患者根据Adams分类法分为3组,其中大梗死42例,作为A组;小梗死39例,作为B组;腔隙性梗死31例,作为C组.对比分析3组诊断结果,包括动脉梗死程度与血管改变情况. 结果 3组动脉硬化程度比较显示,动脉硬化程度差异均有统计学意义,其中C组重度率明显低于B组与A组,同时B组重度率也明显低于A组(P均＜0.05);3组血管改变情况也有显著性差异,其中A组动脉闭塞率明显高于B组与C组,而且B组血管闭塞率也明显高于C组(P均＜0.05). 结论 MRA诊断CI患者,能通过动脉闭塞情况来反映出患者动脉硬化程度,有很高的临床诊断价值.%Objective To discuss the value of magnetic resonance angiography in the diagnosis of intracranial artery stenosis degree in the patients with cerebral infarction (CI).Methods A total of 112 cases of cerebral infarction in our hospital from January 2012 to June 2014 receiving magnetic resonance angiography were enrolled.According to Adams classification,the patients were divided into three groups,group A including 31 cases of large infarction,group B including 39 cases of small infarction,group C including 42 cases of lacunar infarction.The diagnosis results of three groups were analyzed,including arterial infarction and vascular changes.Results The severe rate of group C was lowest,followed by group B and group C (P＜0.05).The artery occlusion rate of group A was highest,followed by group B and group C (P＜ 0.05).Conclusions Magnetic resonance angiography could reflect the degree of arteriosclerosis by the situation of arterial occlusion,which has a high clinical diagnosis value for cerebral infarction.
