摘要
目的探讨基底动脉尖综合征(TOBS)的临床表现及影像学特征。方法回顾性分析30例TOBS患者的临床资料。结果TOBS的临床主要表现为一过性意识障碍、眩晕、眼动及瞳孔的变化、锥体束损害、偏盲或皮质盲、共济失调及记忆功能损害;磁共振(MRI)表现梗死灶在丘脑、小脑、中脑、枕叶、脑桥、颞叶内侧面及胼胝体压部;数字减影血管造影(DSA)表现为基底动脉及椎动脉闭塞或狭窄。结论诊断TOBS需依赖临床表现和MRI表现,DSA能为病变血管提供定位依据,对治疗及预防TOBS有指导作用。
Objective To discuss the clinical manifestation of top of the basilar artery syndrome （TOBS） and its features of magnetic resonance imaging （MRI）/cerebral digital subtraction angiography （DSA）. Method The clinical data of 30 cases with TOBS admitted during past four years were analyzed. Results The clinical manifestation of TOBS comprised the sudden vertigo and unconsciousness with the ophthalmoplegia and the abnormality of the pupils, as well as the paralysis, partial blindness or cortical blindness and ataxia and memory impairment. MRI showed the local infarction in thalami, cerebellum, midbrain, lobus occipitals , pons, temporal inner surface and splenium of corpus callosum. The features of DSA are occlusion and stenosis in basilar artery and vertebral artery. Conclusions The diagnose of TOBS depends mainly on the clinical manifestation and MRI. The DSA application in TOBS can offer the possible location of vascular lesion, and instruct treatment and prevention for TOBS.
