Summary
Routine cervical length (CL) screening in twin gestations did not improve perinatal outcomes. However, it was associated with a significant increase in maternal length of stay (LOS).
Area of Science:
- Maternal-Fetal Medicine
- Obstetrics
- Perinatology
Background:
- Twin gestations face higher risks of preterm delivery and adverse outcomes.
- Cervical length (CL) measurement is a predictor of preterm delivery in singleton pregnancies.
- The utility of routine CL screening in twin gestations remains unclear.
Purpose of the Study:
- To evaluate the impact of routine cervical length (CL) measurements on pregnancy outcomes in twin gestations.
- To compare perinatal and maternal outcomes between twin gestations with and without CL measurements.
Main Methods:
- Retrospective review of twin gestations.
- Data collected from ultrasound database and chart review.
- Comparison of outcomes between groups with and without CL measurements.
Main Results:
- No significant differences in gestational age at delivery, preterm delivery rates, antepartum admissions, cerclage placement, or tocolysis use.
- Significant increase in maternal antepartum length of stay (LOS) in the group with CL measurements.
- No differences observed in neonatal outcomes.
Conclusions:
- Routine cervical length screening in twin gestations does not appear to improve perinatal outcomes.
- Routine CL screening in twin gestations is associated with increased maternal antepartum length of stay.
- Further research may be needed to define the role of CL screening in specific high-risk twin pregnancies.
