This trial is a prospective, multi-center, 1:1 randomized using drug-eluting (Sirolimus) stent versus bare metal stent (BMS) to treat intracranial stenosis of 70-99% degree. The primary endpoint is in-stent restenosis rate(ISR) within 12 months after evascularization procedure of the qualifying lesion during follow-up.
The purpose of the RCT trial is to evaluate whether implantation of drug-eluting stent (DES) is more efficacious than bare metal stent (BMS) in prevention of in-stent restenosis (ISR) and improvement of outmoes for symptomatic intracranial atherosclerotic stenosis. This trial is prospective, multi-center, randomized 1:1 single blind trial using Maurora sirolimus eluting stent versus Apollo bare metal stent conducted in approximately 10 interventional neurology centers in China.
