Success of rescue cervical cerclage at a single institution

Objective: To report the outcomes of rescue cervical cerclages performed at a single institution. Methods: A retrospective study was carried out at a single institution between 2006 and 2011. All patients presenting for cerclage placement were identified. From these patients, those undergoing rescue cerclage were studied. Results: 236 patients met inclusion criteria for cerclage placement. Of these patients, 38 singleton and 5 twin pregnancies underwent a rescue cervical cerclage. In singleton and multiple pregnancies, respectively, there was a significant risk of delivery before 24 weeks (26.3% and 40.0%), 28 weeks (36.8% and 80.0%), 32 weeks (52.6% and 80.0%) and 37 weeks (63.2% and 100.0%). Conclusion: A large percentage of pregnancies treated with a rescue cerclage will reach a gestational age of 24 weeks. However, these pregnancies remain at a high risk of preterm delivery.
