“…Placenta previa associated perinatal mortality (about 45%) in particular was more than two- to threefold of some less developed countries [6, 23] and more than fifteenfold of a report from developed countries [9, 15, 24]. The perinatal deaths associated with placental abruption alone were also too high but were not as high as those in the recent report from Pakistan [25].…”

“…The relatively low perinatal deaths among very premature foetuses (28–33 weeks) may not be a true reflection as there were only a very small number of babies delivered prematurely. Taking into consideration the available intensive neonatal care and the reported neonatal survival rate, by definition, the viable gestational age for foetuses delivered in developed and developing countries including this study starts from 20–24 weeks [9, 15, 24] and 28 weeks [21], respectively. This could mean that if this study had included babies born before 28-week gestation with similar problems, prematurity might have been as well the leading associated problem for high perinatal mortality.…”

A retrospective cohort study design was used to assess predictors of perinatal mortality in women with placenta previa and abruption between January 2006 and December 2011. Four hundred thirty-two women (253 with placenta previa and 179 with placental abruption) were eligible for analysis. Binary logistic regression, Kaplan-Meier survival curve, and receiver operating characteristic (ROC) curve were used. On admission, 77% of the women were anaemic (<12 gm/dL) with mean haemoglobin level of 9.0 ± 3.0 gm/dL. The proportion of overall severe anaemia increased from about 28% on admission to 41% at discharge. There were 50% perinatal deaths (neonatal deaths of less than seven days of age and fetal deaths after 28 weeks of gestation). In the adjusted odds ratios, lengthy delay in accessing hospital care, prematurity, anaemia in the mothers, and male foetuses were independent predictors of perinatal mortality. The haemoglobin level at admission was more sensitive and more specific than prematurity in the prediction of perinatal mortality. The proportion of severe anaemia and perinatal mortality was probably one of the highest in the world.

“…Prior large studies examining the relationship between placenta previa and neonatal outcomes have limited analyses to placenta previa confirmed at delivery, which many argue is the most accurate and precise method of defining placenta previa. 13, 14 Unfortunately, when a patient is diagnosed with placenta previa in the second trimester, one cannot predict whether or not their previa will persist until delivery and must counsel and devise a clinical plan based on the information available at the time. The inclusion of placenta previa diagnosed at second trimester ultrasound makes this study clinically applicable; based on our findings, a patient diagnosed with placenta previa at second trimester ultrasound can be managed with a follow up ultrasound in the third trimester to document placental location but does not need serial ultrasounds for growth.…”

Objective To estimate the association between placenta previa and abnormal fetal growth. Study Design Retrospective cohort study of consecutive women undergoing ultrasound between 15–22 weeks. Groups were defined by the presence or absence of complete or partial placenta previa. The primary outcome was intrauterine growth restriction (IUGR), defined as a birth weight <10th percentile by the Alexander growth standard. Univariable, stratified and multivariable analyses were used to estimate the effect of placenta previa on fetal growth restriction. Results Of 59,149 women, 724 (1.2%) were diagnosed with a complete or partial previa. After adjusting for significant confounding factors (black race, gestational diabetes, preeclampsia, and single umbilical artery,), the risk of IUGR remained similar (adjusted odds ratio 1.1, 95% CI 0.9–1.5). The presence of bleeding did not impact the risk of growth restriction. Conclusion Placenta previa is not associated with fetal growth restriction. Serial growth ultrasounds are not indicated in patients with placenta previa.

“…Neonates born to mothers with placenta previa are more likely to be delivered preterm (<37 weeks) (2,4,10,11,12), stillborn (2,6), or die early in the neonatal period (2,5,6,13). The association between placenta previa and small-for-gestational age (SGA) newborn has been inconsistent, ranging from moderate (4,10) to no risk (2,14).…”

“…The association between placenta previa and small-for-gestational age (SGA) newborn has been inconsistent, ranging from moderate (4,10) to no risk (2,14). The relation between placenta previa and SGA may be explained by suboptimal placental implantation and decreased perfusion to the fetus., Previous studies on this association had varied findings due to differences in their study designs and sample sizes, selection and clinical criteria that define SGA, and availability and adjustment of varied confounding factors (2,4,10,11,14,15). …”

Objective To evaluate whether there is an association between placenta previa and delivery of a small-for-gestational-age (SGA) newborn and to quantify the contribution of individual risk factors for SGA that are associated with placenta previa, stratified by maternal parity. Methods A cross sectional study utilizing the Finnish Medical Birth Register during 2000–2010. All singleton births (N=596,562) were included; major congenital anomalies were excluded. An association between SGA (< 2 standard deviations below the mean) and placenta previa was modeled by parity-specific unadjusted and adjusted statistical models. Results Placenta previa complicated 625 of 249,476 singleton births among nulliparous women (2.50/1,000) and (915 of 347,086 singleton births among multiparous women (2.64/1,000). Among nulliparous women, the most common risk factor for placenta previa was in vitro fertilization (IVF); placenta previa was not associated with an increased prevalence of SGA, controlling for maternal age, smoking, IVF, socioeconomic status, and preeclampsia (aOR=0.81; 95% CI=0.57–1.17). Among multiparous women, placenta previa was associated with a two-fold increased risk of SGA, controlling for maternal age, parity, prior preterm birth, prior caesarean delivery, prior SGA newborn, prior preeclampsia, smoking, IVF, socioeconomic status, and preeclampsia (aOR=2.08; 95% CI=1.50–2.89). Further, only one fourth of the association between SGA and placenta previa could be explained by controlling for risk factors clustering with placenta previa among multiparous women. Conclusions Placenta previa is associated with impaired fetal growth in multiparous but not nulliparous women.

Neonatal outcomes with placenta previa

Abstract: Neonatal complications of placenta previa included preterm birth, congenital anomalies, respiratory distress syndrome, and anemia. There was no increased occurrence of fetal growth restriction.
