中脑梗死与后循环血管状态之间的关系

Correlation between the conditions of posterior circulation and infarctions in midbrain

目的探讨中脑梗死与后循环血管状态之间的关系。方法所有病例均行头部MRI及全脑血管造影检查。结果 32例新发中脑梗死中,5例为中脑独立梗死,27例为中脑伴发后循环其他部位梗死。行DSA后可观察到椎动脉闭塞者14例,椎动脉狭窄者15例;基底动脉闭塞者6例,基底动脉狭窄者9例;大脑后动脉狭窄者8例,大脑后动脉闭塞者5例;无后循环血管病变者5例。结论中脑梗死多伴发后循环其他部位的脑梗死,且多存在椎基底动脉系统的大血管病变,提示临床医生在遇到相关病例时,应重点排查血管方面的原因。

Objective To investigate the correlation between the conditions of posterior circulation and infarctions in midbrain.Methods All the patients received the examinations of head MRI and DSA.Results In all the 32 cases of new infarction in midbrain,5 cases were the isolated midbrain infarcions,while 27 cases were infarctions in midbrain together with other parts of posterior circulation.After DSA,we find there were 14 cases with occlusion of vertebral artery,15 cases with stenosis of vertebral artery.The number of occlusion or stenosis in basilar artery was 6 and 9.There were 8 and 5 cases with cerebral posterior artery stenosis or occlusion.There were also 5 cases with unimpaired arteries of posterior circulation.Conclusion The infarction of midbrain always happens together with other parts of posterior circulation.In addition,there are always big problems with the arteries of posterior circulation.So when meeting the similar patients,the physicians should give the examinations immediately to find out whether there are any big problems with the cerebral arteries.
