Anesthetists performed the cervical plexus block under ultrasound guidance. CEREBRAL FUNCTION MONITORING
The advantage of performing the carotid endarterectomy under regional block is that the
Anatomical landmarks for the superficial cervical plexus block mental status of the patient (e.g. following commands of squeezing a rubber duck,
counting 1-3, not confused) can be monitored throughout the procedure as peri-operative
