  • Title: The value of carotid endarterectomy in treating transient cerebral ischemia of the posterior circulation.
    Author: McNamara JO, Heyman A, Silver D, Mandel ME.
    Journal: Neurology; 1977 Jul; 27(7):682-4. PubMed ID: 559976.
    Abstract:
    The results of a retrospective study of patients undergoing carotid endarterectomy for hemispheric and/or nonhemispheric symptoms of transient ischemic attacks are presented. During an approximately 3-year period of follow-up observation, recurrent cerebral ischemia following carotid endarterectomy was two to three times more frequent among patients with nonhemispheric transient ischemia than among those with hemispheric transient ischemia. Patients with symptoms of both hemispheric and nonhemispheric transient ischemia had the highest frequency of transient ischemic attacks and stroke during the follow-up period and also had the greatest surgical morbidity and mortality. The results of this study suggest that carotid endarterectomy has little or no therapeutic value in treating patients with vertebral-basilar ischemia.
