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.

Wstęp: Związek między obturacyjnym bezdechem podczas snu (OBPS) a miażdżycą jest potwierdzony od wielu lat, choć patomechanizm tego zjawiska nadal nie jest poznany. Celem badania było określenie częstości OBPS u pacjentów zakwalifikowanych do endarterektomii oraz określenie wpływu tej procedury na parametry badania snu i występowanie senności dziennej. Materiał i metody: Do badania włączono 46 pacjentów zakwalifikowanych do endarterektomii otwartej. Przed zabiegiem wykonano badanie snu i zastosowano skalę senności Epworth. U 11 z 46 osób przeprowadzono badania snu także po operacji. Wyniki: Średnia wieku w grupie badanej wyniosła 69,9 lat (± SD = 8,6), 21 pacjentów (45,7%) stanowiły kobiety. Średnia wartość pAHI, ODI, pRDI i procent czasu chrapania wyniosły odpowiednio 16.2 (± SD=15.2), 10.4 (± SD=12.2), 18.9 (± SD=14.9) oraz 9,9 (± SD=17). Prawidłowe wartości pAHI uzyskało 14 pacjentów (30%), podczas gdy łagodny OBPS (pAHI 5–15) zaobserwowano u 13 pacjentów (38%), umiarkowany OBPS (pAHI 15–30) u 11 pacjentów (24%), a ciężki OBPS (pAHI >30) u pacjentów 8 (18%). Średnia wartość skali senności Epworth u 27 z 46 pacjentów wyniosła 6,3 (± SD = 5,6). Pooperacyjne wartości parametrów badania snu u 11 pacjentów nie zmieniły się statystycznie znamiennie. Wnioski: Badanie wykazało występowanie OBPS w stopniu umiarkowanym i ciężkim u 42% pacjentów zakwalifikowanych do endarterektomii, natomiast nie stwierdzono nadmiernej senności w tej grupie. Pokazuje to, że u pacjentów kwalifikowanych do endarterektomii tętnic szyjnych należy wykonać diagnostykę snu w celu wykluczenia OBPS.

The aim of the study was to demonstrate the relation between the operation technique and the early and late complications after the primary and secondary inguinal hernia repairs with the use of artificial material.Material and methods. There were 103 patients qualified for the research from among 140 patients operated within the period of 2003 - 2005. In all patients the same kind of mesh was used (100% Prolene). The operators were asked to fill in a special, original questionnaire. In all patients hernia type was classified during the repair with the use of Nyhus classification, seven key technical details of the treatment were described, subsequently the most frequent post-operative complications and inexpedient symptoms were evaluated - just after the operation and in 18 months time. Statistic one-dimension analysis of X2 method was applied or Fisher's exact test. After indication of the links, multidimensional analysis of logistic regression was used.Results. Based on the multidimensional analysis of logistic regression the links between technical details of the treatment and complications were evaluated. The analysis shows that only high tension has a significant influence on complications' emergence (p<0.0001). Precision of the model amounts to 71%. Additionally each particular complication was analyzed separately.Conclusions. Based on above mentioned results the operation technique algorithm was created with the smallest number of complications. From among analyzed technical details of the operation the special attention should be put at those which are directly and indirectly connected to the mesh binding. The lack of its tension is assumed to be the key factor of the whole procedure that minimizes one of the most serious post-operative complication which is the chronic pain.
