简要总结
The purpose of this study is to evaluate the effectiveness, long-term safety and explore the safety and efficacy factors WILLIS™ intracranial stent graft system in clinical applications.
详细描述
Intracranial aneurysm is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel.WILLIS® intracranial stent graft system is indicated for the treatment of intracranial aneurysms.
This study is a multi-center, prospective registration study.
Recruiting 100 specific patients to undergo a treatment with the WILLIS intracranial stent graft system, while giving the anti-platelet aggregation drugs and other medical therapy.
Patients enrolled will undergo a one-year follow-up.
