Arterial Ischemic Stroke (AIS)

All patients (prospective and retrospective) included will have to present an Arterial Ischemic Stroke (AIS) from a large cerebral vessel occlusion.

The participation in the study will consist in:

  • Plasmatic collection at the time of AIS, for study of plasma biomarkers
  • Additional standardized blinded clinical evaluation at three months after the thrombectomy realized during a phone call, particularly via an assessment of the modified Rankin score.

Primary Outcome Measures :
  1. Clinical outcome [ Time Frame: Day 90 ]
    modified Rankin score (mRS), score 0 to 6 with 0 = no symptoms and 6 = death.

Secondary Outcome Measures :
  1. Efficacy on reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 2b/3) [ Time Frame: Day 1 ]
    Rate of complete or near complete reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 2b/3)

  2. Efficacy on revascularization (>= mTICI 2b) [ Time Frame: Day 1 ]
    Time to achieve TICI 2b or better revascularization

  3. Efficacy on clinical outcome (mRS=0-1) [ Time Frame: Day 90 ]
    Rate of excellent functional outcome defined as a modified Rankin score (mRS) 0-1

  4. Efficacy on functional independence (mRS 0-2) [ Time Frame: Day 90 ]
    Rate of functional independence defined as a modified Rankin score 0-2

  5. Hemorrhage evaluated by imagery [ Time Frame: Day 0 ]
    Rate of symptomatic and asymptomatic intracerebral hemorrhage at MRI or CT scan

  6. Hematoma rate [ Time Frame: Day 1 ]
    Rate of parenchymal hematoma 2

  7. Mortality rate [ Time Frame: Day 90 ]
    Rate of all-cause mortality

  8. Complication rate [ Time Frame: Day 0 ]
    Rate of periprocedural complications

  9. ASPECT (Alberta Stroke Program Early CT score) [ Time Frame: Day O ]
    Measure by Axial imaging, 10-point quantitative topographic CT scan score

  10. Parametric imaging [ Time Frame: Day 0 ]
    Diffusion, volume clinical-diffusion mismatch

  11. Imaging data [ Time Frame: Day 1 ]
    Angiographic imaging

  12. Blood sampling for research purpose [ Time Frame: Day 0 ]
    Search of biomarkers of stroke etiology and recovery
