基底动脉尖综合征的临床与影像表现

The clinical and imaging features of top of the basilar artery syndrome

目的:探讨基底动脉尖综合征的临床及影像学特征。方法:对自2003年8月以来收治的50例TOBS患者的原始资料进行回顾性分析。结果:TOBS多以突然眩晕或意识障碍起病,合并眼球运动障碍及瞳孔异常、运动障碍、视觉障碍等。CT及MRI提示梗死位于中脑、丘脑、小脑、枕叶、颞叶内侧面及桥脑。MRA表现为基底动脉及椎动脉狭窄或闭塞。结论:TOBS有复杂的临床及影像学表现,MR可提供有力的诊断依据。

[Objective]To study the clinical and imaging features of top of the basilar artery syndrome(TOBS).[Method]The clinical data of 50cases with TOBS admitted during past three years were analyzed.[Result]Many patients had symptoms of sudden vertigo or unconciousness,companied with ophthalmoplegia、abnomal pupils、paralysis and dysopia.CT and MRI showed the local infarction in midbrain、thalami、cerebellum、lobus occipital、temporal inner surface and pons.Features of MRA are occlusion and stenosis in basilar artery and vertebral artery.[Conclusion]Clinical symptoms and imaging features of TOBS are diversity and complex.MRI and MRA application in TOBS can offer effective evidence for diagnosis.
