Definitive management for PAS is planned cesarean hysterectomy at what gestational window?

• A. 34-36 weeks with hysterectomy
• B. Induction at 37 weeks
• C. Expectant management until labor begins
• D. Immediate vaginal delivery

Answer: (A)

In placenta accreta spectrum, the definitive approach is to control the risk of massive hemorrhage by removing the placenta and the uterus, which is done via cesarean hysterectomy scheduled before labor begins. Delivering within 34 to 36 weeks strikes a balance: it minimizes the chance of catastrophic bleeding that can occur with spontaneous labor or a later delivery, while still allowing fetal lungs to mature enough to reduce neonatal complications. Inducing at 37 weeks risks delivering during labor or with ongoing placental invasion, which can lead to uncontrolled bleeding and emergency surgical scenarios with higher maternal morbidity. Expectant management until labor begins can precipitate a hemorrhagic crisis. Immediate vaginal delivery would not address the placenta’s invasiveness and would leave the uterus in place, risking severe hemorrhage. Therefore, the planned cesarean hysterectomy at 34–36 weeks is the preferred strategy. In practice, the exact timing depends on placental depth, maternal-fetal status, and institutional resources.
