Background: Placenta previa is one of the complications of pregnancy. Complete placenta previa is the most serious type of placenta previa. It means that the placental tissue completely covers the internal orifice of the cervix. With the rising use of caesarean section (CS) and the increase in maternal age, the incidence of placenta praevia, placenta increta, and their associated complications have continued to increase. Since the early 20th century, the incidence of placenta increta has increased 13-fold. Complete placenta praevia and placenta increta are associated with a higher risk of maternal and fetal complications, especially postpartum hemorrhage. Because of fetal death, lethal anomalies, and maternal complications, the number of patients who are in the second and third trimesters of pregnancy needing to undergo therapeutic abortion is rising. Moreover, in present-day China, many patients with placenta praevia have a history of CS and the condition may be further complicated by placenta increta. Nevertheless, there is a lack of evidence relating to the management of patients with complete placenta praevia who seek therapeutic abortion in the second and third trimesters, and much less regarding placenta increta. The experience with these patients is limited and debate still surrounds the clinical management. So, the aim of this article is to study the delivery mode of therapeutic abortion complicated with complete placenta praevia in the second and third trimesters.
