Stryker Neurovascular
The purpose of the Trevo® Retriever Registry is to collect real world performance data of the Trevo Retriever which is intended to restore blood flow in the neurovasculature by removing thrombus in patients experiencing ischemic stroke.

Ischemic Stroke

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 90 Days
Official Title: Stryker Neurovascular Trevo® Retriever Registry

Further study details as provided by Stryker Neurovascular:

Primary Outcome Measures:
  • Revascularization status assessment at the end of the Trevo Retriever procedure using the modified TICI score [ Time Frame: Modified TICI score assess at the end of the procedure ]

Secondary Outcome Measures:
  • mRS assessment [ Time Frame: 90 days ]
    Assess the rate of participants with mRS </=2 to determine good clinical outcomes at 90 days.

Other Outcome Measures:
  • Assess the rates of device and procedure related serious adverse events (AEs) [ Time Frame: 90 days ]
  • Assess all cause mortality [ Time Frame: 90 days ]
    Report if cause of death is device or procedure related.

Enrollment: 2010
Study Start Date: November 2013
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 1, 2017 (Final data collection date for primary outcome measure)

Detailed Description:

Trevo Retriever Registry is a prospective, open-label, consecutive enrollment, multi-center, international registry that may enroll a maximum of 2000 patients at up to 100 sites worldwide. Revascularization status will be assessed at the end of the procedure using the modified TICI (Thrombolysis in Cerebral Infarction)score. Additional data collection will include:

  1. Day 90 mRS assessment
  2. Day 90 all cause mortality
  3. Neurological deterioration at 24 hours post procedure, defined as a four or more point increase in the NIHSS score from the baseline score
  4. Rates of device and procedure related serious adverse events (AEs)

  • Trevo Retriever is the initial mechanical neuro-thrombectomy device used to remove the thrombus
  • Signed Informed Consent obtained
  • Subject willing to comply with the protocol follow-up requirements
  • Anticipated life expectancy of at least 3 months

Exclusion Criteria:

  • The subject is participating in another mechanical neuro-thrombectomy device trial or any other clinical trial where the study procedure or treatment might confound the study end point.
