Placenta accreta spectrum is optimally managed with a scheduled pre-labor cesarean hysterectomy at approximately what gestational age?

• A. 34-35 weeks
• B. 28-30 weeks
• C. 38-39 weeks
• D. 40 weeks

Answer: (A)

In placenta accreta spectrum, the priority is to prevent catastrophic maternal hemorrhage by delivering in a controlled, pre-labor setting with a planned cesarean hysterectomy. The timing is a balance between minimizing the mother’s bleeding risk and ensuring fetal maturity. Delivering around 34–35 weeks achieves this balance: the baby is generally mature enough to handle early birth, while the absence of labor avoids the heavy bleeding that can occur when the placenta invades the uterine wall during labor. Delivering much earlier (28–30 weeks) would expose the fetus to significant prematurity risks, with limited fetal viability and longer NICU needs. Delaying delivery past 35–36 weeks increases the chance that labor or spontaneous placental separation could trigger uncontrollable hemorrhage, placenta accreta-related complications, or need for an emergent, high-risk cesarean hysterectomy. Thus, the optimal timing is around 34–35 weeks.
