The Results of Cervical Cerclage Performed Between 2012-2016

Abstract

Purpose/Aim: The aim of our study is to share the results of cerclage applied in our clinic and to define the factors affecting the success of cerclage.

Methods: Our study is a retrospective cohort study including 62 singleton pregnant women who underwent McDonald cerclage procedure in our clinic between January 2012 and December 2016. Cerclages were divided into two groups, as ‘therapeutic cerclage’ (TC) and ‘prophylactic cerclage’(PC), and both of these groups were compared. Cerclage success was assessed at two separate endpoints: delivery after 28 gestational weeks and 37 gestational weeks.

Results: The gestational week of cerclage performed was found to be significantly lower in the 'TS’ group than in the 'PS' group [TS: 20,29 ± 4,22 weeks, PS: 16,79 ± 4 , 04 weeks (p = 0.001)]. The length of the cervix was significantly shorter in the 'TS' group than in the 'PS' group [TS: 15,09 ± 4,89 mm, PS: 28,34 ± 6,78 (p <0,001)]. Cerclage-delivery interval found to be significantly longer in the 'PS' group than in the 'TS' group [PS: 18.45 ± 5.1 weeks, TS: 13.62 ± 5, 84 weeks, (p = 0.001)]. The gestational week of cerclage performed [Odds Ratio: 1,452 (1,287- 1,637), p=0,000{for 28th week} and Odds Ratio: 4,529 (2,413- 8,5), p=
0,000{for 37th week}] and the cervical length before surgery [Odds Ratio: 2.57 (1.589 - 5.678) p = 0.0041{for 28th week}] were determined as independent predictors of cerclage success.

Conclusion: There was no significant difference in cerclage success and pregnancy outcomes in the groups of TC and PC. The cervical length before surgery and the gestational week of cerclage are independent predictors for cerclage success.
