title: Mental status outcomes following carotid endarterectomy: a six-month analysis.
abstract: Fifty-one male and two female patients were divided into the following three groups: (a) patients with symptomatic carotid artery disease who received carotid endarterectomies, (b) patients with symptomatic carotid artery disease who either declined or were not candidates for carotid endarterectomies, and (c) patients who received a surgical procedure unrelated to cerebral functioning. The three groups were not significantly different in terms of age or educational level. The subjects were examined using the WAIS, Wechsler Memory Scale, Halstead-Reitan Neuropsychological Battery, Sickness Impact Profile, and Profile of Mood States. The assessments were conducted presurgery and repeated at a 6 month follow-up. The results of two-way analyses of variance revealed a significant trials effect for a majority of the variables, including the average impairment rating and the full scale WAIS IQ. However, significant group x trials interactions were not found for either the neuropsychological measures or the quality of life indices. The results did not support the conclusion of improved mental status or increased psychosocial well-being in patients who received carotid endarterectomies.
