  • Values are n (%) or mean (SD).

  • χ2 test (Fisher's exact for small cell sizes) or Student's t test for the entire patient cohort.

  • Additionally, we dichotomized the cohort into patients in which recanalization times were achieved in ≤60 min (‘Early recan’) and those in which recanalization times extended beyond 60 min (‘Delayed recan’).

  • AFIB, atrial fibrillation; GA, general anesthetic; IA, intra-arterial; IV tPA, intravenous tissue plasminogen activator; IVH, intraventricular hemorrhage; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; SAH, subarachnoid hemorrhage; TICI, Thrombolysis in Cerebral Ischemia.
