What is the appropriate follow-up if placenta previa is identified at the dating scan?

When placenta previa is identified at the dating scan, the appropriate course of action is to schedule ultrasounds at specified intervals, along with a referral if it becomes necessary.

This approach allows for careful monitoring of the placenta's position as the pregnancy progresses. In many cases, the placenta may move away from the cervix as the uterus expands, potentially resolving the condition by the time of delivery. Regular ultrasounds help assess any changes in the placenta's location, providing vital information for planning a safe delivery.

Additionally, continuous monitoring enables midwives and healthcare providers to keep an eye on any complications that may arise. If the placenta previa persists close to delivery, a referral for further evaluation or intervention becomes necessary to ensure both maternal and fetal safety. Therefore, this method of follow-up is consistent with best practices in managing placenta previa, emphasizing both safety and the potential for resolution.
