The mean National Institute of Health Stroke Scale (NIHSS) score on admission was 13 (range 9\u201318). The median time from symptom onset to arrival at hospital was 260\u2005min. The median time lag between arrival at hospital and intra-arterial administration was 70\u2005min. Recanalization by stenting of carotid artery occlusion was successfully performed in all patients. The mean number of recanalizations using the modified PS technique for distally migrated thrombus was 3. Complete recanalization of the MCA was observed in all patients. Symptomatic hemorrhage transformation did not occur during the hospital stay in any of the subjects. At discharge, the mean NIHSS score was 2.2 (range 1\u20136).
