Abstract
Purpose. To investigate the effect of moderate (< 50 %) carotid artery (CA) stenoses on electroencephalogram (EEG) changes associated with on-pump coronary artery bypass surgery (CABG).
Materials and methods. The study involved 39 male patients, 13 of those had moderate CA stenoses. EEG was performed 3–5 days before and 7–10 days after CABG.
Results. It was found that patients with moderate ICA stenoses had higher power values of teta1,2 and beta1-rhythm biopotentials with the eyes closed 7–10 days after CABG compared with patients without the lesions. These changes can be regarded as a manifestation of ischemic neuronal damage during CPB surgery.
Conclusion. Patients with coronary artery disease and moderate CA stenoses are the high risk group of intraoperative neurological complications.
