Abstract
Placenta previa (PP) is a severe complication of pregnancy where the placenta is abnormally placed and partially or totally covers internal os of the cervix. It is associated with potentially life-threatening conditions for the mother, such as antepartum and postpartum bleeding, invasive placentation, need for hysterectomy, blood transfusion, septicemia, and thrombophlebitis. Similarly, adverse fetal and neonatal outcome is observed, with a high risk of preterm birth and perinatal death. Transvaginal ultrasound is the gold standard to assess the relationship between lower placental edge and the internal cervical os. Caesarean section is the recommended mode of delivery for placenta previa. Attempt at vaginal delivery is appropriate for low-lying placenta, but the possibility of postpartum hemorrhage should be considered.
