Unraveling the Efficacy of Therapeutic Interventions for Short Cervix: Insights from a Retrospective Study for Improved Clinical Management

Area of Science:

• Maternal-Fetal Medicine
• Obstetrics
• Neonatology

Background:

• Preterm birth (PTB) is a leading cause of neonatal mortality and morbidity.
• Short cervical length in singleton pregnancies indicates a high risk for PTB.
• Effective interventions are crucial to improve neonatal outcomes.

Purpose of the Study:

• To retrospectively evaluate the efficacy of various therapeutic interventions for PTB.
• To compare the average treatment effects of progesterone, Arabin pessary, and McDonald cerclage, individually and in combination.
• To identify optimal strategies for preventing PTB in high-risk singleton pregnancies.

Main Methods:

• Observational retrospective study of 1146 singleton pregnancies at risk for PTB.
• Patients were grouped based on interventions: intravaginal progesterone, Arabin pessary, McDonald cerclage, or combinations.
• Treatment effects on early, late, and extremely preterm birth rates were evaluated and compared.

Main Results:

• All interventions significantly reduced the incidence of early and late PTB.
• Combinations of progesterone with either a pessary or cerclage showed greater risk reduction than progesterone monotherapy.
• Progesterone combined with cervical cerclage significantly lowered the risk of extremely PTB compared to progesterone alone.

Conclusions:

• Combined therapeutic interventions demonstrate the highest efficacy in preventing preterm birth.
• Individualized treatment approaches are necessary to determine the optimal strategy for specific patient cases.
• Combination therapy, particularly progesterone with cerclage, offers superior protection against extreme preterm birth.
