Does amnioreduction increase success of emergency cervical cerclage in cases with advanced cervical dilatation and protruding membranes?

Abstract

Objective: To investigate whether amnioreduction has any impact on emergency cervical cerclage outcome. Materials and Methods: Data of women who underwent emergency cervical cerclage for advanced cervical dilatation and protruding membranes were analyzed retrospectively. Results: During the study interval, a total of 56 women who were underwent amnioreduction (n=26) and who did not (n=30) were eligible for analysis of the study. Gestational age at cerclage, delivery, and prolongation of pregnancy interval were comparable between the groups (21.3 ± 3.3 vs. 20.6 ± 3.1 weeks; p = 0.44; 28.3 ± 6.1 vs. 28.1 ± 5.6 weeks; p = 0.74; 53.7 ±46.1 vs. 47.3 ± 36.7 days; p = 0.56 respectively). Number of live birth rates and perinatal mortality rates were also not statistically significantly different between the groups (73.1% vs. 70.0%; p = 0.80; 15.4% vs. 13.3%; p = 0.83). Conclusions: Emergency cerclage yields live take home baby rates in more than half of the patients. The decision to perform amnioreduction should be based on suspicion of chorioamnionitis and patient's motivation to know exactly what is the risk of chorioamnionitis.
