INTRODUCTIONPlacenta praevia is characterized by the abnormal placenta overlying the endocervical os, and it is known as one of the most feared adverse maternal and fetalneonatal complications in obstetrics.1 Women with placenta praevia are at an increased risk of second trimester vaginal bleeding.2 Placenta praevia is a source of drastic pregnancy, fetal and neonatal complications, e.g. peripartum hysterectomy, blood transfusion, postpartum hemorrhage, and placenta accreta for the mother, prematurity and intrauterine growth restriction for the fetus and increase in neonatal mortality rates in singleton pregnancies. 3Pathophysiology of placenta praevia is uncertain.Moreover, there appears to be an association between endometrial damage and uterine scarring and subsequent placenta praevia. We have conducted this study to find out the incidence of placenta praevia in Najran University Hospital. 4 METHODSThis study is a cross-sectional descriptive, one-year retrospective and one-year prospective study, carried out from April 2014 to April 2016. All pregnant women attended the antenatal care clinic in Najran University Hospital during the study period, were included. The data was collected in a designed questionnaire after informed consent from all patients in the prospective period.The patient's records in the retrospective period were the source of data. Abdominal Ultrasound scanning was ABSTRACT Background: Placenta praevia is a source of drastic pregnancy, fetal and neonatal complications. There was variable incidence in the literature in different parts of the world and within the same country regions. We carried out this study to find the impact in our area and the possible risk factors for this serious obstetric problem. Methods: This study is a cross-sectional descriptive, one-year retrospective one-year prospective study, carried out from April 2014 to April 2016. All pregnant women attended the antenatal care clinic in Najran University Hospital during the study period, were included. Results: The incidence of placenta praevia was found to be 2.7%. AMONG the study group, the most affected age group was between 20-29 years. Previous placenta praevia and previous caesarean section were the significant risk factors P=0.00 and 0,017 repectively. Conclusions:The incidence of placenta praevia in Najran KSA in this study was high, compared to other regions in Saudi Arabia and the majority of the international figures. Caesarean section and previous placenta praevia were the significant risk factors for placenta praevia in this study.

“…Placenta praevia can result in life-threatening maternal complications such as haemorrhage and shock and in adverse infant outcomes such as prematurity, stillbirth and neonatal death (Crane et al 1999(Crane et al , 2000Bahar et al 2009). National hospital surveillance data from the USA demonstrate a case-fatality rate of 17.3 deaths per 100 000 White women with placenta praevia and 40.7 deaths per 100 000 among Black women (Tucker et al 2007).…”

Potential sources of heterogeneity were investigated using meta-regression.results The overall prevalence of placenta praevia was 5.2 per 1000 pregnancies (95% CI: 4.5-5.9). However, there was evidence of regional variation (P = 0.0001); prevalence was highest among Asian studies (12.2 per 1000 pregnancies; 95% CI: 9.5-15.2)

Background: In placenta previa, the placenta occupies lower uterine segment and is likely to separate during pregnancy, resulting in significant maternal and perinatal morbidity and mortality. It has been well studied as the degree of placenta previa increases, the risk of bleeding also increases. However, there are few studies regarding configuration of placenta in relation to uterine wall (anterior, posterior or lateral) and associated complications. The primary purpose of this retrospective cohort study is to examine the whether the location of placenta in relation to lower uterine segment during caesarean delivery influences development of bleeding complications necessitating various surgical interventions. The secondary objective was to study various factors such as preterm delivery, fetal growth restriction, perinatal deaths and postpartum haemorrhage in relation to location of placenta. Methods: We conducted a retrospective study of 89 patients with placenta previa with ultrasonographically mapped placenta over a period of 5 years. The subjects were further categorized into anterior, posterior and lateral group depending upon location of placenta in relation to uterine wall. Differences between age, parity, history of previous caesarean delivery, antepartum haemorrhage, preterm deliveries, foetal growth restriction, perinatal deaths, operative complications and surgical interventions, placenta accreta and postpartum haemorrhage were studied and also were compared to traditional classification of placenta previa in relation to internal cervical ostium. The statistical analysis of the data was performed according to Pearson Chi-square test, one way ANOVA test using SPSS Software. Results: The overall incidence of placenta previa was 1.01%. Placental location was anterior in 23 women (25.8%), posterior in 49 women ((55%) and lateral in 17 (19.1%). No significant differences were found in these groups regarding age, gestational age at delivery, parity, previous history of caesarean delivery, incidence of antepartum and postpartum haemorrhage. Need for surgical interventions such as uterine artery ligation, internal iliac artery plication, caesarean hysterectomy was not specific any type of placenta previa. 39.1% of anterior, 40% of posterior and 35.2% of lateral placenta previa received blood component therapy and this variation was not statistically significant. The overall perinatal mortality was 45/1000 live births and mortality rate did not vary significantly in any of the groups. Conclusions: It is difficult to assign a maternal or perinatal morbidity risk to a particular type of placental location. The need for specialized surgical intervention such as uterine / internal iliac artery ligation, peripartum hysterectomy can arise irrespective of placental location, whether underneath the surgical incision (anterior), proximity to main uterine trunks (lateral) or encountered after the delivery of the baby (posterior). Pregnancies complicated by placenta previa must be delivered in the hospitals havi...
