Can Placental Thickness predict Fetal Weight?


 
 
 The placenta is the principal influence on fetal birth weight, and it is thought that abnormalities of placental growth may precede abnormalities in fetal growth. Because the placenta may be the first organ to manifest changes of disease in pregnancy, placental features may have a role in screening for pregnancy complications.
 
 
 
 The aim this study is to assess the accuracy of placental thickness (estimated by ultrasonography) in predicting fetal weight.
 
 
 
 This prospective observational study was conducted at Ain Shams University Maternity Hospital November, 15th, 2016 to November, 1st, 2017. 100 Normal antenatal pregnant women at 24-28 weeks of pregnancy who attended antenatal clinic at the department of obstetrics and gynecology, Ain Shams University Maternity Hospital were recruited, after fulfilling the inclusion and exclusion criteria.
 
 
 
 The predictive rule could estimate actual birth weight with an accuracy of ± 0.450 kg (SEest = 0.450 kg). In visits 1 and 2; ± 0.448 kg (SEest = 0.448 kg) in visit 3.
 
 
 
 The actual birth weight was regressed on the placental thickness using simple linear regression to obtain a predictive rule. There is very weak correlation between the actual neonatal weight and placental thickness. The current study deduced a new formula for correction of EFW using placental thickness which has a promising role to offer in the prediction of birth weight.
