A 34-year-old primigravida at 37 weeks of gestation presents to the antenatal clinic. Ultrasound confirms frank breech presentation with flexed hips and extended knees. The patient has no contraindications to vaginal delivery, adequate pelvis on pelvimetry, and estimated fetal weight of 3.2 kg. She is counselled about risks and wishes to attempt vaginal breech delivery. What is the most appropriate next step in management?

Explanation

## Management of Breech Presentation at Term **Key Point:** The Term Breech Trial (2000) demonstrated increased perinatal mortality and morbidity with planned vaginal breech delivery compared to planned cesarean section. However, vaginal breech delivery remains an option in carefully selected cases with experienced attendants. ### Current Evidence-Based Approach **High-Yield:** In 2023 guidelines, the recommended sequence for breech at term is: 1. **Offer ECV first** — success rate 50–60% in multiparas, 40–50% in primiparas 2. **If ECV declined or unsuccessful** → discuss vaginal vs. cesarean delivery 3. **If vaginal breech delivery chosen** → strict selection criteria must be met ### Selection Criteria for Vaginal Breech Delivery | Criterion | Requirement | |-----------|-------------| | **Parity** | Multiparous preferred; primiparas require experienced provider | | **Presentation** | Frank or complete breech (NOT footling) | | **Estimated fetal weight** | 2.5–3.8 kg | | **Pelvis** | Adequate (gynecoid or android) on imaging | | **Maternal age** | <40 years | | **Fetal anomalies** | None on ultrasound | | **Continuous monitoring** | Essential throughout labor | **Clinical Pearl:** This patient meets criteria: primigravida (acceptable with counselling), frank breech, adequate weight, adequate pelvis. ECV should be offered first as it has the highest success rate and converts to cephalic presentation (safest for vaginal delivery). ### Why This Patient Needs ECV Counselling 1. **Success is higher than vaginal breech delivery safety** — ECV success ~50% converts to cephalic (lowest perinatal risk) 2. **If ECV declines**, vaginal breech is defensible only with informed consent and continuous fetal monitoring 3. **Cesarean at 39 weeks is NOT first-line** — it is the fallback if ECV fails or patient declines vaginal trial **Mnemonic:** **BREECH-ECV-PLAN** - **B**reach confirmed → **R**efer for **E**xternal **C**ephalic **V**ersion - **E**CV successful → vaginal cephalic delivery (safest) - **C**V failed/declined → **P**lan vaginal breech (if criteria met) **L**abor with monitoring **A**nd continuous **N**
