POSTOPERATIVE COGNITIVE DISORDERS IN PATIENTS UNDER CAROTID ENDARTERECTOMY

Abstract

Evaluation of the impact of carotid endarterectomy on the cognitive status of patients remains debatable, since patients with atherosclerotic lesions of the carotid arteries suffer from chronic cerebrovascular insufficiency, and changes in the cognitive status of patients after carotid endarterectomy may be due to factors such as increased blood supply to the brain, microembolism after the start of blood flow, and cerebral ischemia during cross-clamping and also the effect of various anesthesia drugs on the cognitive status in these patients is ambiguous.Purpose. To assess age-related changes in cognitive status in patients with atherosclerotic lesions of the carotid arteries in the postoperative periodMaterial and methods. Neuropsychological testing was performed in 128 patients after eversion carotid endarterectomy, divided into age groups and depending on the methods of anesthesia: Propofol group and Sevoflurane group.Results. In patients under the age of 60 years, there is an improvement in cognitive status in the early and late postoperative period, while in patients of the older age group, there is a slowdown in the progression of cognitive dysfunction in both groups of anesthesia.Conclusion. An important criterion for evaluating the surgical prevention of cerebrovascular accidents is clinical effectiveness, in particular, the impact of operations and anesthesia methods on the cognitive sphere of patients of different ages with pathology of the main arteries of the head, which determines the quality of life not only for patients, but also for relatives.
