“…However, Singh et al concluded that posterior placental location was associated with 62.26% risk of IUGR with a significant p value of < 0.0001. 5 The results were similar to a retrospective study conducted by Jackson et al which showed lateral placenta was associated with preterm birth (a OR 2.06, 95% CI, 1.19-3.58). 20 On the contrary, Shumaila Zia et al concluded that preterm labour were associated with posterior placenta with an outcome of 3.7% and a significant p value of <0.001.…”

“…Singh et al concluded that 16% of NICU admissions belong to the high-risk group of IUGR and Preeclampsia which is associated with lateral placentation. 5 These results are contrary to the findings of Devarajan et al which showed lateral placenta with NICU admission of 5.3% and central placenta with NICU admission of 6%. 8 Similarly, Zia et al, Jaisal et al and Jackson et al found no association with placental location and NICU admissions.…”

Background: Placental location can be estimated easily using ultrasonogram by 16 weeks. It can be classified based on its location into central and lateral. Central can be anterior or posterior. Lateral can be left lateral or right lateral. Placental location has been attributed to both normal and abnormal pregnancy and neonatal outcomes.Methods: This is a prospective cohort study conducted in the department of Obstetrics and Gynecology which comprised of 450 singleton gestations between 18 and 24 weeks. The primary objective is to determine the association between placental location and pregnancy outcome and secondary objective is to find out the association between placental location and neonatal outcome. The study population was divided into two groups – central and lateral. Results were analyzed using SPSS version 20, Chi square test and independent two sample t-test.Results: The frequency of central placenta was 377 (83.8%) and lateral placenta in 73 (16.2%). Central placentation had an abnormal outcome in 182(48.3%), lateral placentas with abnormal outcome were 44(60.3%). Abnormal maternal outcomes like hypertensive disorders (33.3%), Intra Uterine Growth Restriction (10.2%), Antepartum haemorrhage (25%), Preterm birth (16.3%) were more in lateral placentation. The number of central placentas having NICU admissions were 62(16.4%) and lateral placenta with NICU admissions were 19(26%).Conclusions: There is a significant association between lateral placentation and abnormal pregnancy and neonatal outcomes. Second trimester ultrasound can be used as non-invasive predictor of adverse pregnancy and neonatal outcomes.

BACKGROUNDPregnancy-induced hypertension is one of the leading causes of foetal and maternal morbidity and mortality worldwide. In our country, the prevalence of the disease is 5-15% and perinatal death rate due to PIH is 20%. Early detection becomes very essential as the disease is detected in advanced stages most of the times. Hence, screening for the prediction of PIH becomes necessary for improving maternal and foetal outcome. Aims-To evaluate the relationship between placental location and occurrence of PIH. To determine whether placental location can be used as a screening test for detection of PIH and to study maternal and foetal outcome in these patients. MATERIALS AND METHODSPrimigravidae with singleton pregnancy, without any medical disorder were considered for the study and were subjected to ultrasound examination to scan for gestational age, placental localisation-Central or lateral, amount of liquor amnii, congenital anomalies. The location of placenta was determined around or more than 24 weeks of gestation with real time ultrasound and repeat ultrasound was done in some patients at a later gestation to confirm the placental location. All patients with unilateral placenta on scan were followed up to delivery and the early detection of PIH reported, also the maternal and neonatal outcome was studied at delivery. Measurements were obtained & reported. The relationship between laterality of placenta and occurrence of PIH noted and discussed. Statistical Analysis Used-Statistical analysis was done using percentages and Chi-square test. Settings and Design-This was a prospective study conducted over a period of 6 months from September 2015 to February 2016 in the Department of Obstetrics and Gynaecology, SMBT Institute of Medical Sciences, Dhamangaon, Nasik. RESULTSThe present study showed the incidence of PIH in primigravidae to be 15.24% and incidence of lateral placentation in primigravidae being 15.8%. Our study also shows that 63 out of 83 primigravidae with lateral placenta developed PIH and 17 out of 425 primigravidae without lateral placenta developed PIH. The sensitivity and specificity of our study being 75.9% and 96.15% respectively. CONCLUSIONEvidence of lateral placenta on ultrasonography is a very useful addition to our armamentarium of antepartum testing for prediction of PIH and its management. Placental localisation has a definite potential to serve as a simple, non-invasive screening test for prediction of PIH. KEYWORDSPlacenta, Pregnancy-induced Hypertension.

Background: Placenta is the vital link between fetus and the uterine wall. Based on location, it can be classified as anterior, posterior, lateral, fundal and low lying. Placental location can be easily determined in the antenatal period using ultrasound. Materials and Methods: Design: Prospective observational study. Study period: One year from January 2018 to February 2019 in a tertiary hospital in Salem district of Tamilnadu. Study population: After informed consent, 200 women with singleton pregnancy of ≥28 weeks attending antenatal OPD were included in the study. Women were followed up with ultrasound at 28 weeks and 34 weeks to identify any maternal and fetal adverse effects such as gestational hypertension, preeclampsia, preterm birth and NICU admission. Results: The mean age of the study participants was 24.3 ± 43 years. Of the 200 women, 42% (n=84) of placenta were situated in fundus, 30% (n=60) were anterior, 18% (n=36) were lateral, 8% (n=16) were posterior and 2% (n=4) were low lying. Gestational hypertension was present in 22%, 13%, 12% in lateral, anterior and posterior placental location respectively. Preeclampsia was seen in 22% in lateral placental location. Preterm labour, PROM, low birth weight and NICU admission were common in posterior and lateral placental location.Conclusion:There was statistically significant association between low lying, posterior and lateral placental location and adverse maternal fetal outcomes. Hence ultrasound can be used as the safe, cost effective, non-invasive tool in predicting the adverse maternal and neonatal outcome.
