Rescue cerclage in IVF pregnancies with second trimester cervical dilatation: Case report and literature review

摘要

Despite being available for over 50 years, cervical cerclage remains one of the controversial interventions in obstetrics. Rescue cerclage is the operative cervical closure of a widely dilated cervix with or without unruptured membrane prolapsus. In the literature, the effectiveness of rescue cerclage in the prolongation of pregnancy is debatable. Prolongation of pregnancy and improvement of neonatal survival is of utmost importance in pregnancies achieved by in vitro fertilization (IVF). We report here two IVF pregnancies with second trimester cervical dilatation treated with rescue cerclage and who delivered healthy babies near term without maternal and neonatal morbidities.
