Brief Summary:
The objective of this study is to collect data on the use of the SOLITAIR FR device for treatment of acute ischemic stroke with large artery occlusion i.e. to investigate, whether the application of SOLITAIR is a safe and feasible method for interventional recanalization of large vessels with favorable patient outcome in acute stroke therapy.

Condition or disease Intervention/treatment Phase
Acute Stroke Device: Solitaire FR, ev3 Phase 2

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Mechanical Recanalization With Flow Restoration in Acute Ischemic Stroke (ReFlow Study)
Study Start Date : September 2010
Actual Primary Completion Date : November 2011
Actual Study Completion Date : November 2011

Intervention Details:
  • Device: Solitaire FR, ev3
    Placement of the stent in the occluded vessel segment, withdrawal in its unfolded state.
    Other Name: device used: Solitaire FR, ev3, USA

Primary Outcome Measures :
  1. Overall frequency of favourable clinical outcome (modified Rankin Scale 0 to 2), and unfavourable clinical outcome or death (modified Rankin Scale 3 to 6) [ Time Frame: Day 90 ]

Secondary Outcome Measures :
  1. Arterial recanalization of occluded target vessel measured by Thrombolysis in Cerebral Infarction (TICI)score of 2b or 3 following the use of the SOLITAIRE FR Device [ Time Frame: Day 0 ]
  2. Excellent functional clinical outcome (modified Rankin Scale 0 or 1) [ Time Frame: Day 90 ]
  3. All causes of mortality [ Time Frame: Day 90 ]
  4. Proportion of patients with rapid neurological improvement (more than 4 points on the NIHSS) during the first 24 hours after treatment. [ Time Frame: Day 1 ]
  5. Symptomatic intracranial haemorrhages up to 24 hours after treatment defined as homogeneous areas of haemorrhage, with or without mass effect or intraventricular extension with neurological deterioration [ Time Frame: Day 1 ]
  6. Time between arterial puncture and Flow Restoration [ Time Frame: Day 0 ]
  7. Time between arterial puncture and TICI 2b or 3 recanalization [ Time Frame: Day 0 ]
  8. Number of SOLITAIRE device runs until recanalization [ Time Frame: Day 0 ]
  9. Number of patients with and degree of stenosis in the treated artery 90 days after recanalization with SOLITAIRE [ Time Frame: Day 90 ]
  10. Number of patients in which thrombus material was preserved [ Time Frame: Day 0 ]
  11. Histological examination of the thrombus material in correlation with TICI 2b or 3 recanalization and favorable clinical outcome [ Time Frame: Day 1 ]
  12. Overall frequency of modified Rankin Scale 0 to 2 at 30 days [ Time Frame: Day 30 ]
