Effectiveness and perinatal outcomes of history-indicated, ultrasound-indicated and physical examination-indicated cerclage: a retrospective study

Abstract

ObjectiveTo evaluate the effectiveness and perinatal outcomes of cerclage procedure according to indication.MethodsThe pregnancy and neonatal outcomes of the patients who underwent cerclage with the diagnosis of cervical insufficiency between January 2016 and December 2020 were retrospectively analyzed. Patients were categorized into three groups: a history-indicated group, an ultrasound-indicated group and a physical examination-indicated group.ResultsSeventy-three patients who underwent cerclage were included in the study. Of these, 41 (56.2%) had history-indicated, 17 (23.3%) had ultrasound-indicated and 15 (20.5%) had physical examination-indicated cerclages. Compared to history- and ultrasound-indicated cerclage group, duration from cerclage to delivery (18.6 ± 6.9 weeks vs 17.8±5.9 weeks vs 11 ± 5.3 weeks, p = 0.003) was significantly lower and delivery < 28 weeks (9.8% vs 5.9% vs 33.3%, p = 0.042) and delivery < 34 weeks of gestation (26.8% vs 11.8% vs 60%, p = 0.009) were significantly higher in physical examination-indicated cerclage group. In physical examination-indicated cerclage, compared with history- and ultrasound-indicated cerclage low birth weight, low APGAR score, neonatal intensive care unit admission and neonatal mortality were higher, although not statistically significant (p > 0.05).ConclusionPregnant women who underwent physical examination-indicated cerclage had higher risks for preterm delivery < 28 weeks and < 34 weeks than history- and ultrasound–indicated cerclage.
