*The five patients evaluated mRS=6 at 18 months are the three patients with mRS=6 at 6 months plus two other patients who died between the 6-month and 18-month follow-ups and for whom the mRS score was attributed as 6 at 18 months.
†On post-procedure evaluations, neurologic deterioration was determined subjectively by the investigator compared with the clinical status on admission. At 6 and 18-month follow-ups, clinical deterioration was defined as an increase in mRS score compared with the corresponding post-procedure value.
