Summary
Transvaginal cervical cerclage is safe and effective for treating incompetent cervix, even when performed earlier in pregnancy. This study found no significant differences in outcomes compared to later placements.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Surgical Procedures
Background:
- Cervical insufficiency is a condition that can lead to preterm birth.
- Transvaginal cervical cerclage is a surgical procedure to prevent preterm birth.
- Current recommendations often suggest cerclage placement between 14-17 weeks gestation.
Purpose of the Study:
- To evaluate the safety and efficacy of transvaginal cervical cerclage placed in early pregnancy.
- To compare outcomes of cerclage placement at different gestational ages.
Main Methods:
- Retrospective review of 33 patients undergoing 38 transvaginal cervical cerclages.
- Patients divided into three groups based on gestational age at cerclage placement: ≤13 weeks, 13-18 weeks, and ≥18 weeks.
- Comparison of demographic data, surgical procedures (McDonald, Shrodkar), and pregnancy outcomes.
Main Results:
- No major surgical complications were observed in any group.
- Overall incidence of preterm labor and birth was 48.6% and 37.8%, respectively.
- A trend favored earlier cerclage placement for preterm labor and birth, but without statistical significance. No significant differences in blood loss, obstetric complications, birthweight, or gestational age at delivery.
Conclusions:
- Transvaginal cervical cerclage is safe and effective when performed in early pregnancy.
- Early cerclage placement may offer a trend towards improved outcomes compared to later placement.
- The findings support considering earlier intervention for cervical insufficiency.
