title: Prediction of hemorrhage in placenta previa.
abstract: Placenta previa poses a high risk for massive hemorrhage, from the antenatal period until after Cesarean section. This condition increases the risk of maternal and neonatal mortality and morbidity. In cases of placenta previa, the prenatal prediction of sudden bleeding during pregnancy and blood loss during Cesarean section, and the assessment of risk for adherence of the placenta using an ultrasound examination, can improve the perinatal outcome. Therefore, ultrasonographic findings associated with the prediction of massive bleeding in cases of placenta previa are reviewed in this article.
