ABSTRACT

Aim and Objectives: Placenta is an important link between a mother and child. The proper & effective functioning of placenta is responsible for the wellbeing of the fetus. This study is designed to investigate about the possibility of using placental thickness as a parameter for estimating gestational age and estimated fetal weight (EFW). Materials and Methods: This study was conducted from March 2013 to Dec 2013 in the department of Radiology and department of Obstetrics & Gynecology, KIMS Hospital, Bhubaneswar, Odisha. A total 176 women were selected, according to the inclusion criteria. The gestational age was estimated by using biparietal diameter[BPD], femur length[FL], abdominal circumference[AC]. The placental thickness was measured at the point of umbilical cord insertion. The data was tabulated in designed clinical data collection sheets which contains all variables of the study[placental thickness, estimated gestational age, estimated(EGA), fetal weight[EFW]. The estimated fetal weight was determined by hadlock formula. Results: The placental thickness is considered as one of the parameters for estimating gestational age of the fetus. Placental thickness appears as an accurate indicator of gestational age in singleton pregnancies. It was observed that the placental thickness was highly significant with gestational age in 3rd trimester(p<0.001).There was a linear regression correlation of placental thickness with gestational parameters like femur length, Biparietal diameter, Head Circumference, Abdominal Circumference. Placental thickness have significantly high correlation with all the above gestational parameters.

Keywords: abdominal circumference (AC), estimated fetal weight (EFW), estimated gestational age (EGA), femur length (FL), head circumference (HC), placental thickness, ultrasonography.
