  1. Data are presented as n (%) or median (interquartile range). ACA, anterior cerebral artery; ASPECTS, Alberta Stroke Program Early Computerized Tomography Score; ICA, internal carotid artery; mTICI, modified treatment in cerebral infarction; NIHSS, National Institutes of Health Stroke Scale; M1, the horizontal segment of the middle cerebral artery; and M2, the insular segment of the middle cerebral artery.
  2. *If both CT and MRI were performed before treatment, the lower one was used.
  3. The utilization of an aspiration catheter as a distal access device was also counted.
