A 32-year-old primigravida at 36 weeks of gestation presents to the antenatal clinic. Ultrasound confirms frank breech presentation. She is hemodynamically stable, with no contraindications to vaginal delivery. What is the most appropriate next step in management?

Explanation

## Management of Breech Presentation at 36 Weeks **Key Point:** External cephalic version (ECV) is the first-line intervention for breech presentation between 36–37 weeks in women without contraindications, as it reduces the need for cesarean delivery and improves perinatal outcomes. ### Rationale for ECV 1. **Timing:** At 36 weeks, there is adequate amniotic fluid and fetal mobility to attempt version with reasonable success rates (60–70% in multiparous women, 40–50% in primigravidas). 2. **Prerequisites Met:** - Singleton pregnancy (implied) - No contraindications (hemodynamically stable, no placental abnormality mentioned) - Informed consent obtained 3. **Outcome:** Successful ECV converts breech to cephalic presentation, allowing trial of vaginal delivery and reducing cesarean morbidity. ### Procedure Details **Pre-ECV Assessment:** - Confirm fetal well-being (NST, ultrasound) - Exclude contraindications (placenta previa, previous cesarean, ruptured membranes, fetal anomaly) - Tocolytic agent (nifedipine or terbutaline) to relax uterus and improve success **Post-ECV:** - Repeat NST to confirm fetal well-being - If successful → counsel for vaginal delivery trial at term - If unsuccessful → plan cesarean section at 39 weeks (planned cesarean is safer than planned vaginal breech delivery in modern obstetrics per Term Breech Trial) **High-Yield:** The Term Breech Trial (2000) showed planned cesarean section for breech presentation reduces perinatal mortality and morbidity compared to planned vaginal breech delivery, making ECV the preferred first step to avoid cesarean altogether. [cite:ACOG Practice Bulletin 161] **Clinical Pearl:** Primigravidas have lower ECV success rates (~40–50%) than multiparous women (~60–70%), but the procedure is still worth attempting before resorting to cesarean. ### Why Planned Cesarean at 39 Weeks Is NOT First-Line Cesarean delivery carries maternal morbidity (infection, hemorrhage, thromboembolism, anesthesia complications) and should be reserved for failed ECV or contraindications to version.
