REVASCAT is a prospective, multicenter, randomized trial seeking to establish whether subjects meeting following main inclusion criteria: age 18-80, baseline National Institutes of Health Stroke Scale = 6, evidence of intracranial internal carotid artery or proximal (M1 segment) middle cerebral artery occlu- sion, Alberta Stroke Program Early Computed Tomography score of > 7 on non-contrast CT or > 6 on diffusion-weighted magnetic resonance imaging , ineligible for or with persistent occlusion after intravenous alteplase and procedure start within 8 hours from symptom onset, have higher rates of favorable outcome when treated with the SolitaireTM FR embolectomy device compared to standard medical therapy alone The primary end-point, based on intention-to-treat cri- teria is the distribution of modified Rankin Scale scores at 90 days. Projected sample size is 690 patients. Estimated common odds ratio is 1•615. Randomization is performed under a mini- mization process using age, baseline NIHSS, therapeutic window, occlusion location and investigational center. The study follows a sequential analysis (triangular model) with the first approach to test efficacy at 174 patients and subsequent analyses (if necessary) at 346, 518, and 690 subjects. Secondary end-points are infarct volume evaluated on CT at 24 h, dra- matic early favorable response, defined as NIHSS of 0–2 or NIHSS improvement = 8 points at 24 h and successful recanali- zation in the Solitaire arm according to the thrombolysis in cerebral infarction (TICI) classification defined as TICI 2b or 3. Safety variables are mortality at 90 days, symptomatic intrac- ranial haemorrhage rates at 24 hours and procedure related complications.
