Note:—ASA indicates American Society of Anesthesiologists; GCS, Glasgow Coma Scale; mRs, modified Rankin scale.

^aAmerican Society of Anesthesiologists grade: 1 = a healthy patient; 2 = patient with mild systemic disease; 3 = patient with severe systemic disease; 4 = patient with severe systemic disease that is a constant threat to life; 5 = moribund patient who is not expected to survive without the operation; 6 = declared brain-dead patient whose organs are being removed for donor purposes.
