Study Description(click to expand)

This study is a prospective, multicenter, objective performance criteria clinical trial to evaluate the safety and efficacy of intracranial self-expanding drug stent system in the treatment of symptomatic intracranial atherosclerotic stenosis. A total of 128 patients are planned to be included. The primary endpoint is the incidence of In-stent restenosis at 6 months after operation (ISR is defined as stenosis greater than 50% within or immediately adjacent (within 5 mm) to the implanted stents and absolute luminal loss greater than 20% at 6 months follow-up imaging.). All patients will have clinical follow-up during intraoperative, 30 days, 6 months, 1 year.
