Methods Pregnancy and neonatal outcomes and placental histopathology reports, from cesarean deliveries (CD) of pregnancies with placenta previa (n=119), between 2009-2015, were reviewed. Results were compared to CD matched for maternal age and pregnancy complications (control group). Placental lesions were classified into maternal and fetal vascular supply lesions, and inflammatory response. Composite neonatal outcome was defined as one or more of early complications: respiratory morbidity, NEC, sepsis, transfusion, seizures, phototherapy, or death. Small for gestational age (SGA) was defined as birth weight < 10th percentile.
