摘要
目的 探讨MRI联合DSA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DSA检查资料,观察MRI显示病变的分布范围和DSA显示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.76.2%(16/21)的患者中存在椎动脉和基底动脉形态异常,23.8%(5/21)椎、基底动脉DSA检查未见明显异常.结论 MRI联合DSA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.
Abstract
Objective To explore the diagnosis and treatment application of MRl and DSA of TOBS.Methods 21 cases with TOBS using MRI and DSA inspection data were retrospectively 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.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.76.2％ (16/2l)of the survivals showed abnormal performance in vertebral and basilar artery,23.8％ (5/21)had no significant abnormalities in vertebral and basilar artery after DSA examination.Conclusion The joint inspection of MRI and DSA provides comprehensive clinical information,which can be used as the preferred TOBS screening and diagnostic methods.
