The association of placenta previa with history of cesarean delivery and abortion: a metaanalysis

Article Abstract:

Women who have had cesarean sections or abortions may be at greater risk for placenta previa, with increasing risk as the number of prior cesarean sections increase. Placenta previa is an abnormally low placental attachment in the uterus. A systematic review of all published studies on placenta previa, including four studies involving 170,640 women, indicates that the risk of placenta previa increases with the number of prior cesarean sections. Risk is also increased in women having had a previous abortion. Uterine scarring may account for this increased risk.

The effect of placenta previa on neonatal mortality: a population-based study in the United States, 1989 through 1997

Article Abstract:

Babies born to women who have placenta previa are about four times more likely to die at birth than other babies, especially if born at term. They also had lower birth weights, according to a study of 22,368,235 pregnancies. Placenta previa occurs when the placenta is so low inside the uterus that it partially or totally covers the opening into the vagina.

The influence of mode of delivery on twin neonatal mortality in the US: Variance by birth weight discordance

Article Abstract:

The study examines if neonatal mortality rates (NMR) based on birth weight discordance (BWD) differ based on mode of delivery. The twins with BWD <40%, modes of delivery has no effect on NMR.
