NCT03199404

Brief Summary

This purpose of this retrospective, single-arm, non-randomized, multi-center study is to collect real-world data on the effectiveness of using the TRAP technique in acute ischemic stroke patients undergoing mechanical thrombectomy.

Outcome Measures

Primary Outcomes (4)

  • Recanalization after Endovascular Intervention

    Revascularization as assessed via Thrombolysis in Cerebral Infarction (TICI) score (TICI 2b/3) in affected vessels

    Day 0: Conclusion of Thrombectomy Procedure

  • Time to Recanalization

    The time required to attain recanalization (TICI 2b/3) in affected vessels

    Day 0: Conclusion of Thrombectomy Procedure

  • Number of Passes for Recanalization

    The total number of passes with the stent retriever need to attain recanalization will be captured.

    Day 0: Conclusion of Thrombectomy Procedure

  • Distal Emboli

    Incidence of distal emboli (both to affected vessel and new vessel) will be assessed

    Day 0: Conclusion of Thrombectomy Procedure

Secondary Outcomes (4)

  • Neurologic Outcomes

    90 days after treatment

  • Functional Outcomes

    90 days after treatment

  • Adverse Events

    Day 1, Day 5-7 and Day 90

  • TRAP Technique

    Day 0: Conclusion of thrombectomy procedure

Study Arms (1)

Treated Subjects

Subject experiencing an acute ischemic stroke in which imaging demonstrates a vascular occlusion located in the distal internal carotid artery (ICA) through the distal middle cerebral artery (MCA) and in which the TRAP technique is used for at least the first two thrombectomy passes per occluded vessel and that meet the other inclusion-exclusion criteria.

Device: TRAP

Interventions

TRAPDEVICE

Mechanical thrombectomy performed with the combination of a stent retriever that is partially re-sheathed and withdrawn under constant aspiration along with the use of a balloon guide catheter for distal flow control during thrombectomy.

Treated Subjects

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients presenting with acute ischemic stroke at participating hospitals in which the TRAP technique is used for mechanical thrombectomy.

You may qualify if:

  • Subject experiencing an acute ischemic stroke in which imaging demonstrates a vascular occlusion located in the distal internal carotid artery (ICA) through the distal middle cerebral artery (MCA)
  • Subjects in which the TRAP technique is used for at least the first two thrombectomy passes per occluded vessel
  • Subjects that range in age from 18-85
  • Subjects with a prestroke modified Rankin scale of 0-1 and presenting with an NIHSS of 8-30
  • Subjects that the operator feels may be treated with endovascular therapy
  • Subjects in which computed tomography (CT)/Magnetic Resonance Imaging (MRI) demonstrates an infarct size of less than 70cc on MRI or Alberta Stroke Program Early CT (ASPECTS) score overall of 6 or better
  • Subjects in which groin puncture can be obtained within 6 hours of symptom onset (with or without Total Plasminogen Activator administration)
  • Subjects who have consented in accordance with local Institutional Review Board requirements

You may not qualify if:

  • Absence of large vessel occlusion on neuroimaging
  • Evidence of tandem occlusion on neuroimaging
  • Platelet count \< 100 x 10³ cells/mm³ or known platelet dysfunction
  • Contraindication to CT and/or MRI (i.e., due to contrast allergy or prior implant that precludes MRI imaging)
  • Previously documented contrast allergy that is not amenable to medical treatment
  • Women who are pregnant or breastfeeding at time of intervention
  • Evidence of brain hemorrhage on CT and/or MRI at presenting hospital
