Outcome Measures

Primary Outcomes (1)

  • the Modified TICI(Thrombolysis in Cerebral Infarction) Scale at the End of Procedure

    The primary endpoint is measured using the modified TICI scale at the end of procedure.Success of primary endpoint was defined as a modified TICI score of 2b or better at the end of procedure. Primary endpoint will be analyzed by percentages, frequencies and the 95% confidence interval of the percentage of success. The 95% confidence interval will be calculated using ClopperPearson exact method. Note: Modified TICI score has 6 grades: 0(No Perfusion), 1(Penetration with Minimal Perfusion), 2(Partial Perfusion), 2a(Partial filling with \<50% of the entire vascular territory is visualized), 2b(Partial filling with ≥50% of the entire vascular territory is visualized), 3(Complete Perfusion). Higher scores mean a better outcome.

Study Population

Populations met the inclusion/exclusion criteria above

You may qualify if:

  • Age ≥18
  • Subjects experiencing acute ischemic stroke due to a large vessel occlusion who are eligible and suitable for restoration of blood flow using any approved Trevo Retriever in the neurovasculature to remove thrombus
  • Trevo Retriever is planned to be the primary mechanical neuro-thrombectomy device to remove the thrombus
  • Subject or subject's legally authorized Representative (LAR) has signed the study Informed Consent Form
  • Subject willing to comply with the protocol follow-up requirements

You may not qualify if:

  • mRS \>2
  • Any known coagulopathy
  • Anticipated life expectancy less than 3 months
  • Known absolute contraindications to the use of required study medications or agents (e.g., heparin, aspirin, clopidogrel, radiographic contrast agents, etc.)
  • Preexisting neurological or psychiatric disease that would prevent complete the study required evaluations
  • 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.
