Q. A 31-year-old G2P1 woman at 23 weeks of gestation, with a previous cesarean section comes to her obstetrician for a regular prenatal visit. She complains of occasional painless vaginal bleeding and otherwise, she is normal. Her temperature is 98.6°F (37°C), pulse is 80/min, blood pressure is 120/84 mmHg, and respirations are 1/4min. Physical examination is consistent with 23 weeks of gestation and fetal heart rate is 150/min. Ultrasonography shows a placenta that is implanted deeply into the myometrium, with loss of the normal hypoechoic retroplacental zone. The placenta extends beyond the expected border and shows increased vascularity. There is no evidence of placental invasion into adjacent structures. What is the most appropriate next step in management for this patient?
