Effectiveness of Different Cerclage Indications in Cervical Insufficiency and Perinatal Outcomes: A Single-Centre Retrospective Analysis

Preterm birth is associated with perinatal morbidity and mortality, and cervical cerclage is an effective intervention for preventing cervical insufficiency. This retrospective study was conducted to evaluate the effects of maternal, obstetric, and perioperative variables on the prolongation of gestational duration and neonatal outcomes in pregnancies where cerclage was performed. To this end, the medical records of 93 singleton pregnancies in which cervical cerclage was performed were evaluated. The findings showed that gestational age was significantly longer and delivery occurred later in the history-based cerclage, ultrasonographic short cervix, and emergency cerclage groups. Cervical funneling and early removal of the cerclage strongly influenced shorter gestational age and reduced live birth-discharge rates. While obstetric complications contributed to adverse neonatal outcomes, progesterone use and maternal comorbidities were not associated with gestational age at delivery. In conclusion, the success of cerclage is multidimensional; indications and the perioperative process play a decisive role.
