Carotid endarterectomy is the most common surgical procedure performed for stroke prevention. Our neurosurgeons at Penn State Hershey Medical Center have special training and experience in this procedure. The majority of these procedures are performed under regional anesthesia (the area of the operation is made numb with an injection so patients are not uncomfortable). Since they are awake, patients are less likely to suffer side effects to their heart or lungs from the anesthesia and overall recovery is faster. Most patients will leave the hospital the next day.
