Predictive factors for emergency cervical cerclage efficacy in singleton and twin pregnancies: A retrospective cohort study

Emergency cerclage is associated with high offspring survival in both singletons and twins. Clinical factors, among advanced cervical dilation and elevated infectious parameters prior to placement, significantly affect its efficacy, although prolapsed membranes and GA at cerclage placement emerged to be the most critical predictors for preterm birth <28 weeks. These findings provide valuable insights that can be used in the counseling of couples about the pros and cons of an emergency cerclage.
