Systematic Evaluation of Patients Treated With Stroke Devices for Acute Ischemic Stroke (STRATIS) Registry

This study is ongoing, but not recruiting participants.
Information provided by (Responsible Party):
Medtronic Neurovascular Clinical Affairs Identifier:
First received: September 8, 2014
Last updated: April 14, 2017
Last verified: April 2017
The purpose of this registry is to assess clinical outcomes, and different factors that may affect these clinical outcomes such as systems of care, associated with the use of Covidien market-released neurothrombectomy devices intended to restore blood flow in patients experiencing acute ischemic stroke due to large intracranial vessel occlusion.

Ischemic Stroke

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 90 Days
Official Title: Systematic Evaluation of Patients Treated With Stroke Devices for Acute Ischemic Stroke (STRATIS) Registry

Further study details as provided by Medtronic Neurovascular Clinical Affairs:

Primary Outcome Measures:
  • Status of revascularization at the end of the interventional procedure [ Time Frame: Day 0 ]
    Assess revascularization using Thrombolysis in Cerebral Infarction (TICI) score at the end of the procedure

Secondary Outcome Measures:
  • Incidence of Neurological Events of Interest [ Time Frame: up to 90 days post index procedure ]
    Evaluate events causing neurological deterioration (defined as ≥ 4 worsening points from baseline on the NIHSS scale)

Other Outcome Measures:
  • All-cause mortality [ Time Frame: up to 90 days post index procedure ]
  • Functional and Neurological Deficit [ Time Frame: Discharge & 90 days ]
    Evaluate mRS and NIHSS

  • Incidence of device and procedure related serious adverse events [ Time Frame: up to 90 days post index procedure ]
  • Time to Revascularization [ Time Frame: Day 0 ]

Estimated Enrollment: 1000
Study Start Date: August 2014
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Detailed Description:
This is a prospective, multi-center, non-randomized, observational registry of acute ischemic stroke patients that have or will undergo treatment with the use of a Covidien market-released neurothrombectomy device (as the initial device used to remove the thrombus) within 8 hours of stroke symptom onset, at the discretion of the investigator and independent of participation in this registry. This registry may enroll up to 1000 patients.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Acute Ischemic Stroke Patients

Inclusion Criteria:

  • Patient or patient's legally authorized representative has given Informed Consent according to Good Clinical Practices (GCP) and/or IRB and/or local or institutional policies.
  • Patient has experienced an acute ischemic stroke due to large intracranial vessel occlusion (with associated symptoms) and has been or will be treated with a Covidien market-released neurothrombectomy device, as the initial device used to remove the thrombus.
  • Treatment within 8 hours of stroke onset.
  • Pre-Stroke Modified Rankin Scale (mRS) score ≤ 1 (immediately) prior to stroke onset.
  • Pre-treatment National Institutes of Health Stroke Scale (NIHSS) ≥ 8 and ≤ 30.

Exclusion Criteria:

  • Concurrent participation in a multicenter randomized study.
