摘　　要：目的:探讨MRI联合减影CTA在基底动脉尖综合征(top of the basilar syndrome,TOBS)诊断及治疗中的应用价值。方法:回顾性分析21例TOBS患者的MRI和减影CTA检查资料,观察MRI显示病变的分布范围、椎基底动脉血管流空状况、椎基底动脉血管结构。结果:梗死灶分布于两侧丘脑、中脑、小脑、枕叶、颞叶。呈对称性病变13例,单侧分布8例。椎动脉及基底动脉血流异常者14例。76.2%(16/21)的患者中存在椎动脉和基底动脉形态异常,13例表现为基底动脉尖部变细,38.1%(8/21)的患者为椎、基底动脉动脉瘤,5例椎、基底动脉减影CTA检查未见明显异常。结论:MRI联合减影CTA检查为临床提供较为完整的诊断信息,可以作为TOBS筛选和首选的诊断方法。Objective：To explore the diagnosis and treatment application of MRI and CTA of TOBS.Methods：21 cases with TOBS using MRI and subtraction CTA inspection data were retrospectivey analyzed so as to observe the distribution range of pathological change,the void flow of vertebral or basilar artery and the structure of vertebral or basilar artery by MAI.Results：The infarction lies in the both sides of the thalamus,midbrain,cerebellum,occipital lobe,and temporal lobe.There were 13 cases with symmetrical infraction and 8 cases with unilateral infarction.14 cases had abnormal blood flow in vertebral artery and basilar artery.76.2%（16/21） of the survivals showed abnormal performance in vertebral and basilar artery,13 cases of whom had thin apex in basilar artery.38.1%（8/21） of patients surfered from the vertebral,basilar artery aneurysm,and five cases had no significant abnormalities in vertebral and basilar artery after subtraction CTA examination.Conclusion：The joint inspection of MRI and subtraction CTA provides comprehensive clinical information,which can be used as the preferred TOBS screening and diagnostic methods.
