Introduction-Placenta may be referred to as the ‘mirror of the perinatal period, which has not been sufficiently polished’.Abnormal thickness of placenta is well recognised as a diagnostic harbinger in a wider spectrum of pathological events. Placenta thickness is very much related to fetal development and may be a key in perinatal outcome. At term the placenta is approximately 3 cm thickness and weighs about 500 to 600 grams. Aims& Objectives-To describe association of placenta thickness with gestational age, estimated fetal weight, actual birth weight and perinatal outcome. Materials & Methods-This prospective observational study was conducted in the Department of Obstetrics and Gynaecology in Rama Medical College Hospital & Research Centre, Kanpur from August 2022 to September 2023. 90 pregnant women with randomly selected pregnancy in third trimester were taken. Ultrasound examination done. Placenta thickness was measured in mm trans-abdominally..ResultThere was positive correlation between placenta thickness and estimated fetal weight at Different gestational age with p<0.001. There was also positive correlation between placenta thickness and actual birth weight with p<0.001. Perinatal outcome was good in women with normal placental thickness. ConclusionUltrasonographic measurement of placental thickness in antenatal period can be effective, simple and non-invasive Method of estimating fetal growth. The measurement of placental thickness should therefore be carried out routinely during Obstetric USGs.
