Advanced maternal age and the increasing number of cesarean sections have led to a higher frequency of placenta praevia and/or accreta. Antenatal screening of these pregnancies, using the maternal medical history and the second trimester anatomy ultrasound scan, is necessary. Placenta praevia and/or accreta are responsible for a number of serious feto-maternal complications. Placenta praevia is a risk factor for IUGR, preterm delivery and retroplacental hematoma. Post-partum hemorrhage is the principal maternal complication. High risk pregnancies of placenta praevia should have a close follow-up. Cesarean section is preferred when the distance between the placenta and the internal cervical os is less than 2 cm. In cases of post-partum hemorrhage, conservative management seems to be effective. An experienced multidisciplinary medical team is needed during the conservative or surgical management.
