Since no unnecessary risks should be taken in these patients, especially those with transient cerebral ischemic attacks and asymptomatic carotid bruits, some method of monitoring the adequacy of cerebral blood flow or a reliable means of cerebral protection during endarterectomy must be employed if strokes are to be prevented and aggravation of neurological deficits is to be avoided.

Elsewhere in this issue (p 1023) White and associates report on the anesthetic management for carotid artery surgery.
