Why the study?
The study was conducted to analyze postoperative electroencephalography power changes in patients undergoing simultaneous coronary artery bypass grafting and carotid endarterectomy.
Does simultaneous CABG and CEE exacerbate the severity of brain damage compared to isolated CABG?
Does simultaneous CABG and CEE exacerbate the severity of brain damage compared to isolated CABG?
Simultaneous CABG and carotid endarterectomy does not appear to significantly worsen postoperative brain damage compared to isolated CABG, as measured by EEG.
Answers are grounded in this paper and cite their sources.
Simultaneous CABG and carotid surgery was not associated with worse brain damage than isolated CABG; leaves open need for randomized confirmation.
AIM: To analyze the postoperative electroencephalography (EEG) power changes in patients after simultaneous coronary artery bypass grafting (CABG) and a left- or right-sided carotid endarterectomy (CEE). MATERIAL AND METHODS: /Hz), theta1 (4-6 Hz), theta2 (6-8 Hz), alpha1 (8-10 Hz), alpha2 (10-13 Hz) rhythms were analyzed, the hemispheric asymmetry (HA) coefficient of the rhythms was calculated. RESULTS AND CONCLUSION: In the early postoperative period, the power of theta1 and theta2 rhythms increased compared to the preoperative level regardless of the type of cardiosurgical intervention. A local character of postoperative theta activity changes was revealed in the left+CEE CABG group, whereas the most pronounced decrease of the alpha-rhythm HA coefficient was observed in the right CEE+CABG group at the 7-10th day after surgery in comparison to the preoperative level. The results of the study suggest that the simultaneous coronary and carotid surgery does not significantly exacerbate the severity of brain damage compared to isolated CABG.
