Abstract：Objective To study the risk factors and outcome of symptomatic BAAS.Methods Eighty symptomatic BAAS patients served as a BAAS group and 80 symptomatic anterior circulation stroke (ACS) patients served as a ACS group in this study.The risk factors for symptomatic BAAS were compared.The symptomatic BAAS patients were further divided into mild-moderate stenosis group (n =43) and severe stenosis group (n=37),progressive stenosis group (n =34) and non-gressive group (n=46),survival group (n=42) and death group (n=38) respectively.The relationship between risk factors and outcome of symptomatic BAAS was analyzed.Results The rate of male patients and the incidence of hypertention were significantly higher in BAAS group than in ACS group (75.0％ vs 57.5％,80.0％ vs 66.3％,P＜0.01).The history of ischemic stroke and smoking was related with the severity of BAAS (P＜0.05).Premonitory symptoms were re lated with the progression of BAAS (P＜0.01).Pulmonary infection and tracheal intubation or tracheotomy were related with the outcome of BAAS (P＜0.01).Conclusion Male gender,hypertension,and history of ischemic stroke and smoking are the independent risk factors for symptomatic BAAS which is less likely to progress in patients with premonitory symptoms.Pulmonary infection and tracheal intubation or tracheotomy are the independent risk factors.
