Abstract

The purpose of this study was to estimate the time interval between elective cerclage removal and spontaneous delivery. Singleton pregnancies with McDonald cerclage were evaluated for the interval between elective cerclage removal (36-37 weeks) and spontaneous delivery. We also compared spontaneous delivery within 48 hours after cerclage removal between women with ultrasound-indicated vs history-indicated cerclage. We identified 141 women with elective cerclage removal. The mean interval between removal and delivery was 14 days. Only 11% of women delivered within 48 hours. Women with ultrasound-indicated cerclage were more likely to deliver within 48 hours, compared with women with history-indicated cerclage (odds ratio, 5.14; 95% confidence interval, 1.10-24.05). The mean interval between elective cerclage removal and spontaneous delivery is 14 days. Women with cerclage who achieved 36-37 weeks should be counseled that their chance of spontaneous delivery within 48 hours after elective cerclage removal is only 11%.
