Abstract
Background/aim: This study evaluated the efficiency of cervical cerclage and pessary in addition to vaginal progesterone to prevent preterm birth in twin pregnancies.
Materials and methods: This retrospective case-control study included 46 cases of twin pregnancy with cervical insufficiency delivered at Ankara Bilkent City Hospital between January 2022 and January 2024. Patients were grouped as those receiving cervical cerclage in addition to vaginal progesterone (n = 10), cervical pessary in addition to vaginal progesterone (n = 11), and only vaginal progesterone (n = 25). Patients' data were obtained from the hospital's database. Obstetric parameters (gravidity, parity, abortion, artificial reproductive technologies, second-trimester abortion) and ultrasound parameters (cervical length, intraamniotic sludge) were recorded. Gestational week at birth, latency period (diagnosis to delivery), and delivery after 34 weeks were evaluated for effectiveness. All parameters were compared between groups and evaluated for effectiveness as an independent factor for preterm birth.
Results: The primary effectiveness parameters of latency period, birth week, and delivery after 34 weeks did not differ statistically between groups. When the parameters were evaluated independently of treatment groups for their effects on delivery after 34 weeks with multivariate regression analysis, the presence of intraamniotic sludge was found to be a negative independent factor for delivery after 34 weeks (p = 0.03).
Conclusion: Cervical cerclage or pessary in addition to vaginal progesterone had no additional benefit for achieving birth after 34 gestational weeks. The only factor that had a negative effect on birth after 34 gestational weeks was the presence of intraamniotic sludge. Our clinical experience with twin pregnancies may provide insight into treatment options for clinicians.
期刊介绍：
Turkish Journal of Medical sciences is a peer-reviewed comprehensive resource that provides critical up-to-date information on the broad spectrum of general medical sciences. The Journal intended to publish original medical scientific papers regarding the priority based on the prominence, significance, and timeliness of the findings. However since the audience of the Journal is not limited to any subspeciality in a wide variety of medical disciplines, the papers focusing on the technical details of a given medical subspeciality may not be evaluated for publication.
