大脑中脑动脉供血区急性脑梗死病灶类型与进展性脑梗死的关系

摘要

目的 探讨大脑中动脉供血区急性脑梗死病灶类型及其与进展性脑梗死的关系.方法 回顾性分析140例大脑中动脉供血区急性脑梗死患者病历资料及脑MRI、DWI、MRA影像资料,其中进展组71例,非进展组69例.结果 2组脑梗死类型均可见流域性脑梗死、分水岭脑梗死、纹状体内囊梗死、腔隙性梗死,进展组以分水岭脑梗死(45.1%)、纹状体内囊梗死(46.5%)为主,非进展组以流域性脑梗死(44.9%)为主,2组脑梗死病灶类型比较,差异有统计学意义(χ2=24.829,P<0.01).结论 大脑中动脉供血区急性分水岭脑梗死、纹状体内囊梗死易表现为进展性脑梗死.%Objective To investigate the association between the infarction type caused by ischemic middle cerebral artery and progressive cerebral infarction.Methods Clinical data and imaging data of brain MRI,DWI and MRA from 140 cases with a-cute cerebral infarction caused by ischemic middle cerebral artery were retrospectively analyzed.There were 71 cases in progressive group and 69 in non-progressive group.Results The both two groups showed territorial infarction(TI),watershed infarction (WI),striatocapsular infarction(SCI)and lacunar infarction(LI).In addition,WI(45.1%)and SCI(46.5%)were the dominant types in progressive group,while TI(44.9%)was the main type in non-progressive group,which showed significant difference be-tween two groups(χ2=24.829,P<0.01).Conclusion Acute WI and SCI caused by ischemic middle cerebral artery may be prone to present progressive cerebral infarction.
