title: Early placenta previa and delivery outcome.
abstract: Ultrasound scan showed some degree of placenta previa in 503 patients. Of this group, 5.6% (28) had clinically significant bleeding or documented placenta previa at delivery. A scoring system based on placental localization was not successful in predicting who was at high risk for bleeding. However, the likelihood of clinically excessive bleeding did significantly increase if the placenta previa was noted after 30 weeks' gestation. The study did not find a greater incidence of small-for-gestational-age babies in women with low-lying placentas.
