Placenta previa and vasa previa: time to leave the Dark Ages

Abnormal Placentation: Placenta Previa, Vasa Previa, and Placenta Accreta.

Placental disorders such as placenta previa, placenta accreta, and vasa previa are all associated with vaginal bleeding in the second half of pregnancy. They are also important causes of serious fetal and maternal morbidity and even mortality. Moreover, the rates of previa and accreta are increasing, probably as a result of increasing rates of cesarean delivery, maternal age, and assisted repro...

Estimating Returns to Birthweight by Placenta Previa

Worse future outcomes of infants with lower birthweight are widely documented, but the underlying causal relationship remains controversial. Recent causal studies rely mostly on within-twin variations, and tend to find significant effects of birthweight on long-term outcomes, but substantially smaller effects on infant health than by standard regression estimates. To improve our understanding o...
