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

Description

Inclusion Criteria:

  2. Age 19 or greater
  3. mRS before qualifying stroke, 0 to 2
  4. Baseline NIHSS score 4 or more
  5. CT ASPECTS > 5 or MR ASPECTS > 4
  6. Good collateral statues on CT angiogram (collateral grade by Calgary group, 4 or 5) or corresponding to DEFUSE 3 or DAWN trial on perfusion imaging.
  7. Onset (last-seen-well) time to femoral puncture time < 24 hours
  8. Anticipated life expectancy of at least 12 months
  9. Patients who undergo endovascular thrombectomy with EmboTrap II as the first-line device
  10. Signed informed consent for study enrollment

Exclusion Criteria:

  1. Multiple simultaneous large vessel occlusions
  2. Pregnancy
  3. Severe contrast allergy or absolute contraindication to iodinated contrast agent
  4. Patient has a severe or fatal combined illness that will prevent improvement of follow-up or will render the procedure unlikely to benefit the patient.

Design Details

  • Observational Models: Cohort
  • Time Perspectives: Prospective

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.
