Abstract:
Objective:To investigate the application value of electroencephalogram (EEG) combined with regional cerebral oxygen saturation (rSO 2) in monitoring cerebral perfusion during carotid endarterectomy (CEA). Methods:A retrospective analysis of clinical data of 42 patients with atherosclerotic carotid artery stenosis admitted to and accepted CEA in our hospital from January 2018 to December 2019 was performed. CEA was performed under EEG combined with rSO 2 monitoring. The efficacy and safety of EEG combined with rSO 2 in monitoring cerebral perfusion abnormalities during CEA were analyzed. Results:After carotid artery occlusion, 24 patients (57.1%) had normal EEG and rSO 2; 15 (35.7%) had abnormal changes of EEG, among whom 13 (31.0%) were accompanied by rSO 2 anomaly; 16 (38.1%) had abnormal rSO 2, among whom 13 (31.0%) were accompanied by EEG anomaly. Of these 18 patients with abnormal EEG and/or rSO 2 monitoring, 17 patients recovered after increasing their blood pressure and 1 patient recovered after diverter tube usage. Intraoperative EEG and rSO 2 monitoring results were consistent (Kappa=0.745, P=0.000). The positive rates of combined monitoring, EEG alone or rSO 2 alone were 42.9%, 35.7% and 38.1%, respectively. All patients were evaluated clinically and radiologically before discharge, and no new ischemic lesions or clinical symptoms were found. Conclusions:EEG and rSO 2 monitoring are well consistent in CEA; the combined monitoring can make up for the deficiency of single monitoring to increase surgical safety.
