Abstract

Objective: This is a prospective descriptive hospital-based study about relationship between placental thickness and estimated fetal weight in third trimester pregnant Sudanese ladies at Omdurman Maternity Hospital (Sudan). Methodology: The study group included 207 women randomly selected. In this study we want to study the normal thickness of placenta among Sudanese pregnant ladies ultrasound growth parameters used for fetal weighing are Biparietal Diameter (BPD), Femur Length (FL) The Abdomen Circumference (AC). Measuring placental thickness in (cm) at the level of cord insertion site, along with these parameters could be of great value. The patient was scanned in supine position with a moderately distended bladder. Result: there is a strong correlation between placental thickness and bi parietal diameter, femur length, abdominal circumference, and so with the estimated fetal weight. The measurement of placental thickness showed the maximum thickness 4.3 cm, the minimum thickness 1.5 cm, the mean of placental thickness 3.1 cm, the median of placental thickness 3.1 cm, the stander deviation 0.64111 and every 1 cm of placental thickness increase fetal weight by 0.88 kg. We conclude that fetal weight and age can be determined by measuring placental thickness.
