研究目的:

评估使用已上市涂层血流导向密网支架治疗颅内未破裂动脉瘤后,采用单一抗血小板药物治疗方案的安全性和有效性。如果本探索性研究安全性可接受,将基于本研究数据结果继续设计开展密网支架植入后的单抗和双抗治疗的随机对照研究。 评估患者对单一抗血小板药物治疗方案的依从性与耐受性,为后续关键临床研究完善患者筛选、治疗及随访流程提供依据。  

Objectives of Study:

Evaluate the safety and efficacy of using a single antiplatelet therapy regimen with a marketed coated blood flow guided dense mesh stent for the treatment of intracranial unruptured aneurysms. If the safety of this exploratory study is acceptable, a randomized controlled trial of monoclonal antibody and bispecific therapy after dense mesh stent implantation will continue to be designed based on the data results of this study. Evaluate patients' compliance and tolerance to a single antiplatelet therapy regimen, providing a basis for improving patient screening, treatment, and follow-up processes in subsequent key clinical studies.
