Abstract
OBJECTIVE
To assess the effectiveness of elective history-indicated cervical cerclage according to obstetrical history.
STUDY DESIGN
We analyzed pregnancy outcome of a retrospective cohort of women who have had history-indicated McDonald's cerclage. Principal outcome was gestational age (GA) at delivery.
RESULT
Between January 2003 and December 2013, 205 women were included. We analyzed population in two risk groups: 1- Low-risk (≤2 prior preterm birth (PTB)/second trimester loss (STL), or prior success of cerclage), 2- High risk (≥3 prior PTB/STL, or prior failure of cerclage). In the high-risk group, there was a higher frequency of deliveries before 37 weeks (47.5% vs. 24.5%, P=0.001, OR=2.79, 95% CI [1.49-5.23]). Fifty percent of women (n=6/12) delivered before 37 weeks in case of three or more prior PTB/STL, and 51% (n=24/47) in case of prior failure of cervical cerclage.
CONCLUSION
Elective cervical cerclage may be indicated for women with≤2 prior PTB/STL, or prior successful cerclage. For women with≥3 prior PTB/STL, trachelorraphy or cervico-isthmic cerclage could be possible alternatives to cervical cerclage.
