Balloon-expandable DES for ICAS Registry Study (BDES-ICAS Registry)

Официальное название

Clinical Outcome of Balloon-Expandable Drug-Eluting Stenting For Patients With Intracranial Atherosclerotic Stenosis: a Prospective, Multicenter, Real-World Registry Study

Обзор

To study the clinical outcomes after implantation of balloon-expandable drug-eluting stents in patients with symptomatic intracranial atherosclerotic stenosis in prevention of composite event of any stroke and death within 30 days and ischemic stroke in the territories of the responsible artery from 31 days to 1-year.

Подробное описание

This study is a prospective, multi-center, real world, registry study. This study aimed to evaluate the effectiveness of balloon-expandable drug-eluting stents in treating stenosis in the C2-C7 segments of the internal carotid artery and V4 artery which with high prevalence of calcified plaques in ICAD.

Вмешательства

• Устройство Balloon-expandable drug-eluting stent
  Balloon-expandable drug-eluting stent (BDES) is the device comprises of a balloon expandable sirolimus eluting stent and a delivery catheter that features a rapid exchange catheter design with a semi-compliant balloon located at its distal end.

Первичные конечные точки

• Any stroke or death within 30 days of implantation or any revascularization procedure OR an ischemic stroke in the territory of the symptomatic intracranial artery between 31 day to 1 year. [Срок оценки: 12 months after implantation]

Вторичные конечные точки (5)

• Any cerebral events within 1 year [Срок оценки: 12 months after implantation]
• Periprocedural events [Срок оценки: within 30 days after implantation]
• In-stent restenosis(ISR) rate [Срок оценки: 12 months after implantation]
• Technique success rate [Срок оценки: During the procedure]
• Functional outcome measured by modified Rankin Scale and NIH stroke scale (NIHSS) score [Срок оценки: Every year after implantation during 5 years]
