Effectiveness of emergency cerclage in cervical insufficiency

Abstract

Objective: To assess the effectiveness of emergency cerclage versus conservative management in improving obstetric and neonatal outcomes in women with clinically evident cervical insufficiency.

Methods: Retrospective cohort study conducted on all women with a single viable pregnancy diagnosed with cervical insufficiency between the 14th and 24th gestational week without pPROM, clinical chorioamnionitis, vaginal bleeding, treatment-resistant uterine contractions or life-incompatible fetal anomalies, from January 2009 to December 2014. Obstetric and neonatal outcomes were compared between women who underwent cerclage and those who refused, preferring a conservative therapy.

Results: Eighteen women underwent emergency cerclage and 19 were managed with a conservative therapy. Mean gestational age at delivery, time from diagnosis to delivery and rate of term birth were significantly higher in the first cohort. Those variables show a linear inverse correlation with the degree of cervical dilatation, with better outcomes in patients who underwent cerclage with a dilatation lower than 5.0 cm. No difference in mode of delivery were found.

Conclusion: Emergency cerclage is a valid therapeutic option between the 14th and 24th gestational week in presence of cervical insufficiency when signs of premature labour or infection are not present, with lower expectations with a dilatation greater than 5 cm.
