AN ULTRASONOGRAPHIC STUDY OF PLACENTAL THICKNESS AND GESTATIONAL AGE IN SECOND & THIRD TRIMESTER
Journal Title: PARIPEX-Indian Journal of Research - Year 2017, Vol 6, Issue 8
Abstract
The placenta is a sprightliness of fetus in utero, as it function for normal growth & development of fetus. So if the growth of fetus is compromised it can be detected by the measurement of placenta. The purpose of our study was to determine normal range of th th placental thickness & its correlation with gestational age in second & third trimester. 100 pregnant females between 14 to 38 week weeks of gestation referred from antenatal clinics the department of Radiodiagnosis in association with the department of Anatomy. Females aged below 35 years without any medical complications were included for routine antenatal ultrasound. Study was carried out on seimen Acuson 300 ultrasound machine using 3.5MHZ convex probe . The placental thickness was measured at the level of umbilical cord insertion in both longitudinal & transverse direction. The ultrasonic gestational age is determined by measuring the Biparital Diameter, Head Circumference, Abdominal Circumference & Femur Length. The mean value of the placental thickness along with the respective standard deviation were calculated for different gestational weeks and compared th with gestational age statistically in order to find its correlation. The maximum mean placental thickness is 19.82±3.42 at 19 th week of gestation & 38.9±0.04 at 38 week of gestation with a significant positive correlation between placental thickness and gestational age r=0.82 & r= 0.79 in second and third trimester.Placental thickness can be used as an accurate sonographic indicator in assessment of gestational age due to its linear correlation.
