Effect of Carotid Stenosis Severity on Patterns of Brain Activity in Patients after Cardiac Surgery

Background: The negative effects of high-grade carotid stenosis on the brain are widely known. However, there still insufficient data state in patients with small and after isolated or combined coronary surgery. This EEG-based study aimed to analyze effect severity associated activity changes neurophysiological test results undergoing artery bypass grafting (CABG) without endarterectomy (CEA). Methods: One hundred forty cardiac surgery underwent a clinical neuropsychological examination multichannel EEG before 7–10 days Results: CA stenoses less than 50% demonstrated higher values theta2- alpha-rhythm power compared both CABG. In addition, who right-sided CABG+CEA had generalized “slowdown” CABG left-sided patients. Conclusions: on-pump accompanied by specific re-arrangements frequency–spatial patterns electrical dependent degree stenoses. information obtained can be used optimize process preoperative postoperative management, as well search for neuroprotection safe surgical strategies this category
