Abstract

Objectives The objective of this study was to evaluate the correlation between placental thickness in the second and third trimesters with gestational age, weight, and fetal outcome. Background Ultrasonography enables the evaluation of the placenta and the detection of placental abnormalities using different parameters such as placental thickness and volume or special techniques like three-dimensional power Doppler. Materials and methods This cohort study was conducted at the Departments of Obstetrics and Gynecology of Menoufia University Hospitals and Shebien Elkom Teaching Hospital from June 2017 to May 2018. This cohort study comprised 100 pregnant women who were attending the antenatal clinic at 24 weeks and were followed-up at 32 and 36 weeks. Detailed history was taken to rule out medical and surgical illnesses that could affect the study. Thorough general, physical, and obstetrical examinations were carried out. US examinations were performed at three visits: first between 24 and 28 weeks, second between 28 and 32 weeks, and third between 32 and 36 weeks. Results There was a significant positive correlation between placental thickness and birth weight in the second and third trimesters. The mean age of cases was 28 ± 5 years. Mean birth weight was 3243 ± 402 g, and mean placental weight was 511 ± 64 g. US measures of placental thickness in the first, second and third visit were 24.91 ± 1.27, 29.50 ± 1.23, and 34.60 ± 1.6 mm, respectively. Conclusion Measurement of placental thickness by ultrasonography is a good predictor tool for estimating the fetal weight.
