Summary
External cephalic version (ECV) successfully converts breech presentations to vertex, reducing cesarean births. This procedure, particularly effective in multiparous women, leads to better outcomes and earlier hospital discharge.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
Background:
- Breech presentation at term complicates delivery.
- External cephalic version (ECV) is a procedure to manually turn the fetus.
- Cesarean delivery is often required for breech presentation.
Purpose of the Study:
- To evaluate the success rate and outcomes of ECV.
- To assess the impact of ECV on cesarean delivery rates.
- To identify factors associated with successful ECV.
Main Methods:
- 72 patients underwent ECV from 34 weeks gestation.
- Procedures were performed under tocolysis with ultrasound and cardiotocograph monitoring.
- Success rates were compared between primigravidas and multiparas.
Main Results:
- Overall ECV success rate was 51.4%.
- Success rates were 35% in primigravidas and 71.4% in multiparas (p < 0.005).
- Successful ECV significantly reduced lower segment cesarean section (LSCS) and breech presentation rates (p < 0.0001) with no fetal complications.
Conclusions:
- ECV is an effective procedure for converting breech to vertex presentation.
- Multiparity is associated with higher ECV success rates.
- Successful ECV reduces the need for cesarean delivery and leads to earlier discharge.
