Placenta previa is used to describe a placenta that is implanted over or very near the internal cervical os and the complete placenta previa is defined that the internal os is covered completely by placenta. This obstetric complication is associated with high risks for maternal hemorrhage and emergency peripartum hysterectomy can be the only effective action to take, although it carries many morbidities for the women especially those with low parity. Although, nowadays the obstetrician can diagnose placenta previa before delivery, it is still one of the important causes of maternal mortality. The only safe and appropriate mode of delivery for placenta previa is by cesarean delivery. In the absence of accreta, this can usually be accomplished using a lower segment uterine incision. Because of cutting through the placenta, it is often associated with increased maternal bleeding. In addition, the umbilical cord will be also excessive blood loss when the placenta is transected. Theoretically, random placenta margin incision can effectively avoid the damage of the placenta and reduce the maternal blood loss.
