Introduction: The association between obstructive sleep apnea and atherosclerosis has been confirmed for a long time, but the pathomechanism is still unknown. The aim of this study was to investigate the prevalence of OSA in patients scheduled for endarterectomy and the influence of this procedure on sleep parameters and sleepiness. Materials and methods: 46 patients scheduled for open carotid endarterectomy were enrolled in the study. Sleep study was carried out and Epworth Sleepiness Scale (ESS) was used preoperatively . In 11 out of 46 patients, sleep study was performed both before and after surgery. Results: The mean age of the group was 69.9 years (± 8.6), 21 patients (45.7%) were female. For 46 patients mean pAHI, ODI, pRDI and %snoring were 16.2 (± SD=15.2), 10.4 (± SD=12.2), 18.9 (± SD=14.9) and 9,9 (± SD=17), respectively. Normal pAHI was noticed in 14 patients (30%), while mild (pAHI 5-15), moderate (pAHI 15-30) and severe (pAHI>30) OSA was observed in 13 (38%), 11 (24%), and 8 (18%) subjects, respectively. The mean ESS score for 27 out of 46 patients was 6.3 (± SD=5.6). The postoperative results of sleep study in 11 patients showed no significant change. Conclusions: This study revealed the prevalence of moderate to severe OSA in 42% of patients scheduled for endarterectomy, while no excessive daytime sleepiness was observed in this group. The results of the study show that patients with carotid atherosclerosis should undergo sleep diagnosis in order to rule out obstructive sleep apnea.
