Fig. 1. Neurologic outcome by modified Ranking Scale in all patients (n = 96) and in patients who received general anesthesia (n = 48) or local anesthesia, mild sedation. No patient who received general anesthesia recovered without a deficit (scale, 0), and the percentage of patients that had a good neurologic outcome (scale, 0–2) was much lower than among patients that received local anesthesia (dotted line). mRS = modified Ranking Scale.
