Abstract :

Aim:To estimate gestational age by ultrasonographic measurement of placental thickness, at the level of umbilical cord insertion. •Material &Method :A prospective study was conducted on 272 antenatal women with gestational age from 11weeks to 40 weeks, from October 2017–June 2019, who came for normal antenatal ultrasound to Subharti Medical Hospital, Meerut. • Result:In our study,the placental thickness gradually increased from 11.47 mm at 11 weeks to 36.55mm at 40 weeks. From 11 to 35 weeks of gestation, the placental thickness ( in mm) almost matched the gestational age in weeks. Thereafter from 36 – 40 weeks the growth of placental thickness was lower by 1–3 mm. Conclusion: The relationship between the placental thickness and gestational age is linear and direct. Placental thickness (in mm) measurement can be an important additional parameter for estimating gestational age along with other parameters especially from 11 to 35 weeks of gestation.
