Summary
Cerclage surgery for premature cervical ripening is not generally beneficial and may increase perinatal risks. It is only superior in specific cases, such as early gestation or a history of pregnancy loss.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Surgical Intervention Efficacy
Background:
- Premature cervical ripening poses risks for adverse pregnancy outcomes.
- Cervical cerclage is a surgical intervention aimed at preventing preterm birth.
- The general efficacy of cerclage for premature cervical ripening requires further clarification.
Purpose of the Study:
- To evaluate the effectiveness of cerclage operation versus conservative management for premature cervical ripening.
- To identify specific patient subgroups who may benefit from cerclage.
- To question the unselected indication for therapeutic cerclage due to potential risks.
Main Methods:
- Retrospective matched-pair analysis of 142 patients (71 cerclage, 71 conservative).
- Patients were matched based on parity, gestational age, and cervix score.
- Subgroup analysis based on medical history and clinical data was performed.
Main Results:
- Cerclage operation was not generally advantageous for premature cervical ripening.
- Higher perinatal morbidity was observed in the cerclage group.
- Cerclage was superior only in cases of cervical ripening before 25 weeks gestation or an 'open cervix' with a history of miscarriage/premature delivery.
Conclusions:
- Unselected cerclage for premature cervical ripening is questioned due to increased perinatal morbidity.
- Specific indications for cerclage include early gestation (<25 weeks) and a history of pregnancy loss with an open cervix.
- Prospective controlled studies are needed to confirm proposed treatment guidelines.
