简要总结
Endovascular therapy is increasingly used for patients with moderate-to-severe acute ischemic stroke.This study will compare the efficacy and safety of RECO(a novel, self-expanding stent retriever) with Solitaire FR within 8 hours of stroke onset caused by the large vessel occlusion.
详细描述
RECO is a novel, self-expanding stent retriever, designed to yield rapid flow restoration in acute cerebral ischaemia. The proposed study is a multicenter, randomized, prospective, parallel-group, open-label clinical trial with a blinded outcome, to test the RECO(a novel, self-expanding stent retriever), as compared with Solitaire FR stent retriever.

结局指标
主要结局
Revascularization Status
时间窗: Post-procedure, immediate=at the end of the procedure, per last angiogram during treatment
Revascularization, defined as at least TICI 2a in the vascular territory treated at end of the neuro interventional procedure Thrombolysis in Cerebral Infarction (TICI) grading system for perfusion (ie blood flow through a vessel) Grade 0:No Perfusion. No antegrade flow beyond the point of occlusion. Grade 1:Penetration With Minimal Perfusion. Grade 2:Partial Perfusion. Grade 2a:Only partial filling (\<2/3) of the entire vascular territory is visualized. Grade 2b:Complete filling of all of the expected vascular territory is visualized, but slower . Grade 3:Complete Perfusion.
次要结局
- Clinical Outcomes at 90 Days(90-day)
- all-cause mortality at 90 days(procedure through 90 days)
- intracranial hemorrhages(24 hours)
