title: [Effects of carotid endarterectomy on various neuropsychologic parameters. A neuropsychologic longitudinal study].
abstract: Carotid endarterectomy was performed in 25 patients with symptomatic cerebrovascular disease. All patients underwent detailed neuropsychological investigations immediately before surgery, immediately after surgery, and again after a follow-up period of 14 months. Immediately after surgery the flicker fusion frequency was temporarily reduced, indicating an impairment of global cognitive functioning. Postoperatively, verbal attention was found to be improved, particularly in younger patients, in patients with TIA, and in patients with left-sided operation. Finally, visual retention (Benton) was improved at the end of the observation period, especially in older patients and in patients with left-sided operation. Considering the complexity of pathologic brain perfusion, the effects of carotid endarterectomy can only be explained if a multidimensional approach is adopted.
