  • *Values were adjusted for age, atrial fibrillation, treatment with rtPA, baseline NIHSS score, time from onset to groin puncture and occlusion site.

  • ICA, internal carotid artery; IVT, intravenous thrombolysis; NIHSS, National Institutes of Health Stroke Scale; NIHSS, National Institutes of Health Stroke Scale; rtPA, recombinant tissue plasminogen activator; TM, thrombus migration.
