Objective To compare the curative effect between stenting and aggressive medical therapy for severe symptomatic intracranial Mori A type vertebrobasilar artery stenosis.Method A retrospective study was carried out by analyzing the medical records about 122 cases with severe symptomatic Mori A type intracranial vertebrobasilar artery stenosis.The patients were divided into drug treatment group and stenting group.The primary outcome was defined as stroke,transient ischemic attack (TIA) and death.The primary outcome and mRS scores were compared between the two groups.Results There was no difference of the rate of 30-day primary outcome(5.8% vs 13.2%) between the two groups (P=0.272).The incidence of accumulative non-primary outcomes and proportion of mRs scores≤2 in stenting group were higher than those in drug treatment group in the one year (respectively,92.8% vs 74.2%,P<0.05;92.8% vs 75.5%,P<0.01).Conclusion For the patients with severe symptomatic Mori A type intracranial vertebrobasilar artery stenosis,endovascular stenting was safe and effective,which was better than drug treatment in prevention of re-ischemia within one year.%目的 比较Mori A型颅内椎基底动脉重度狭窄血管内支架成形术与单纯药物治疗疗效上的差异.
