“…She oscillates between 0, 28% and 1.97% according to the studies. 3 The results of this meta-analysis rhyme with those reported in the African studies (Table 3). In the present study, the frequency of placenta previa has oscillates between 1.3% in 2003 to 1.4% in 2012 with a peak of 2.9% in 2007.…”

Background: The obstetrical haemorrhage constitutes the first cause of mother death, among the causes of these haemorrhages: the placenta previa. That is why we initiated this study for determine epidemiology of placenta previa in our service. The aim objective of this study was to determine the evolution and epidemiology of the placenta previa in our department.Methods: It was a cross-sectional and comparative study of 10 consecutive years. We compared two groups: with and without placenta previa. We performed a multivariate analysis using the logistic regression model as well as the Odds Ratio and its 95% confidence interval.Results: We recorded 504 cases of placenta previa among 30323 deliveries (1.7%). Age, parity and previous placenta praevia have been the recovered risk factors (p <0.001). Among the studied pathologies only placental abruption was strongly associated with placenta previa (p <0.001). However, there were no differences between the two groups according to rates of endometritis, postpartum haemorrhage and maternal death (p >0.05). Indeed, there was a significantly higher incidence of stillbirths, Apgar score <7, transfer of new-borns and small birth weights in the placenta previa group (p <0.001).Conclusions: The most significant rick factors associated with placenta previa are high maternal age, high parity and previous placenta previa, caesarean section and abortion.

“…7 Placenta previa was more commonly present among multiparous women (75.8%) which is similar to study conducted by faiz. 3 Most common type was type 1 placenta previa in 23 (37.2%) cases followed by type 2 in 19 cases (30.6%). 13 cases (20.9%) were of complete placenta previa which was similar to study conducted by Vaishali et al (22.7%).…”

Background: The reported incidence for placenta previa averages 0.3% or 1 case in 300 to 400 deliveries. Multiparity, advanced maternal age, cigarette smoking, previous caesarean delivery, history of abortions or uterine surgical procedures are some of the risk factors contributing to the development of placenta previa. Massive obstetrical haemorrhage in placenta previa is associated with severe maternal morbidity and mortality. A significant number of mothers can be saved if right approach of management is followed in placenta previa.Methods: The present case study is a retrospective analysis carried out in a tertiary care centre to study the risk factors and maternal and perinatal outcome in cases of placenta previa. The study included antenatal patients diagnosed as placenta previa on sonography at or >26 weeks of pregnancy. Data was compiled and statistically analysed.Results: Incidence of Placenta Previa in our study was 0.54%. 73.2% patients had history of previous cesarean sections. 53.6% patients were referred from outside. 98.2% patients delivered by caesarean section. Obstetric hysterectomy was required in 3.5% of total cases. 10.7% cases required the ICU admission after delivery. There was no maternal mortality in the study group. The mean gestational age at delivery was 35±2.4weeks. The mean APGAR at 5 min was 9±2.2.Conclusions: Increasing rates of caesarean sections in present era indicate that incidence of Placenta Previa is expected to rise. Good antenatal care, availability of emergency obstetric services, infrastructure, blood bank facility, HDU and ICU care and NICU services can improve maternal and neonatal outcome.

Etiology and risk factors for placenta previa: an overview and meta-analysis of observational studies

Abstract: Future etiological studies on placenta previa must, at the very least, adjust for potentially confounding effects of maternal age, parity, prior Cesarean delivery and abortions.
