目的探讨基底动脉尖综合征(TOBS)的病因、临床表现和影像学表现,加深对这种疾病的认识。方法回顾性分析38例TOBS患者的原始性资料。结果 TOBS患者以中老年为主,主要病因为脑栓塞及脑血栓形成,高危因素有高血压、糖尿病、心脏病、高血脂等,临床表现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、偏盲、可伴有行为异常等,CT不能清楚显示TOBS早期梗死病灶,磁共振弥散加权扫描(DWI)能准确显示TOBS梗死病灶部位及数目,磁共振血管成像(MRA)能直接反应椎动脉、基底动脉及大脑后动脉情况。结论 TOBS主要依赖临床及影像学表现综合诊断,磁共振检查对于早期诊断基底动脉综合征作用明显优于CT,DWI为早期脑梗死发现的首选检查序列,早期全面综合治疗可以提高生存率。
Objective To explore the etiology, clinical manifestations and imaging manifestations of TOBI and to deepen the understanding of this disease. Methods The original data of 38 patients with TOBS were retrospectively analyzed. Results The main causes of TOBS were middle-aged and elderly patients. The main causes were cerebral embolism and cerebral thrombosis. The high-risk factors were hypertension, diabetes, heart disease, hyperlipidemia, etc. Most of the clinical manifestations were sudden vertigo or disturbance of consciousness. (CT) can not clearly show the early infarction of TOBS, DWI can accurately display the location and number of TOBS infarction, magnetic resonance imaging (MRA) Can directly reflect the vertebral artery, basilar artery and posterior cerebral artery. Conclusions TOBS mainly relies on the comprehensive diagnosis of clinical and imaging findings. MRI is superior to CT in early diagnosis of basilar artery syndrome. DWI is the first choice for detecting early cerebral infarction. Early comprehensive and comprehensive treatment can improve the survival rate.
