ABSTRACT
Objective To explore the efficacy,safety and short-term effects of endovascular therapy in the treatment of the symptomatic high-grade basilar artery stenosis.Methods Two hundred thirteen patients with the symptomatic high-grade basilar artery stenosis (>90%) confirmed by MRA,CTA or DSA was treated by endovascular intervention,the changes of clinical symptoms,the success rate and short-term follow-up results was analyzed.Results Endovascular stent was successfully placed in 209 patients with symptomatic high-grade basilar artery stenosis and the success rate was 98.12%.The degree of vascular stenosis was significantly reduced after stenosis (Before vs After93.70%±2.51% vs 11.60%±3.90%).Eight patients had complications (3.76%) including 7 cases of ischemic stroke and 1 case of subarachnoid hemorrhage.The average follow-up duration was 18.70±3.80 months.Two hundred two patients underwent a second DSA and the mean vascular stenosis was (13.80%±4.20%).Five patients developed in-stent restenosis (ISR),of which one was symptomatic.Conclusion Endovascular therapy of the symptomatic high-grade basilar artery stenosis is safety and efficacy.The 1.5 years follow-up results reveal good patency rate and excellent prevention of posterior circulation ischemia.
