Abstract :

Objective : The aim was to investigate relationship between placental thickness and fetal weights during second & third trimester. Material Method : A study was conducted on 100 pregnant females between 13 weeks and 38 weeks of gestation referred from antenatal clinics to department of Radio diagnosis in association with the department of Anatomy from 20152016. All singleton pregnant women aged between 15 and 35 years for routine antenatal ultrasound were included. Patient more than 35years, Twin pregnancy,diabetes, diagnosed cases of fetal hydrops pregnancy with chromosomal anomaly, placenta previa & placenta auptia The placental thickness was measured transabdominally by placing the ultrasound transducer perpendicularly to the plane of the placenta, at the level of umbilical cord insertion and mean reading was measured along with fetal weight at second and third trimester. Pearson�s correlation analysis was used to establish the degree of relationship between placental thickness and birth weight. Placental thickness and gestational age was correlated and statistically analysed. Result : The maximum mean placental thickness at 26 th week is 29.76 �2.163and at 38 th week is 38.12 � 2.09 mm was recorded. The mean fetal weight at 26 th week is879.5� 59.15 and at 38 th week is 3169.66� 187.5 indicating increase in Placental thickness with fetal weight (r=079 ,p =0001:r =0.50,p =0.004). Placental thickness has a strong positive correlation with fetal weight in 2nd trimester as compare to 3rd trimester. Conclusion : According to our study, birth weight has a positive relationship with both second and third trimester placental thickness. Obstetric ultrasonography should routinely measure placental thickness as it will indicate earliest sign of Intra–uterine growth rate(IUGR),however placental thickness change could not predict low birth weight.
