First-pass Recanalization With EmboTrap II in Acute Ischemic Stroke (FREE-AIS)
March 13, 2020 updated by: Yonsei University
This study is a prospective, open-label, multi-center, registry study, designed to to documents that EmboTrap II usage as a thrombectomy device for emergency large vessel occlusion (ELVO) in terms of the rate of First Pass Recanalization (FPR).
Patients with ELVO will initially underwent mechanical thrombectomy usig EmboTrap II.
FPR is defined as modified Tissue Thrombolysis In Cerebral Ischemia (mTICI) 2b or 3

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Rescue stenting group
|
The subjects will receive endovascular treatment for acute stroke according to standard clinical practice.
Specifically, using a stent retriever, contact aspiration EmboTrap II.
The number of thrombectomy attempts is at the operator's discretion.
Combination of balloon guide catheter or intermediate catheter is recommended.
