The predilection for placenta praevia is mostly in patients who have undergone multiple operations on the uterine cavity, such as abortion, curettage, and multiple pregnancies. In this case, if there is a bleeding situation of aggressive placenta praevia, it should be treated actively and quickly, rehydrated with anti-shock treatment and blood transfusion preparation at the same time, and emergency obstetric surgery should be performed as fast as possible, while pediatricians should be invited to assist in surgical guidance and help in neonatal resuscitation. In summary, women of childbearing age should pay attention to uterine protection to avoid pregnancy due to multiple operations.
