A comparative study of placental morphometry in diabetic and normal mothers in a tertiary care hospital of West Bengal

Among the hundred cases ranging from 19-38 years, fifty placentae were from normal uncomplicated pregnancies and the rest from diabetic mothers. In case of normal pregnancies, the average (±standard deviation) placental weight, volume, thickness, diameter, area and circumference were 513.3 (±53.13) g; 437.4 (±59.8) cm3,1.79 (±0.24) cm, 17.5 (±1.52) cm, 242.19 (±40.21) cm2, 54.95 (±4.78) cm respectively. In case of diabetic mothers, the corresponding values were 579.2 (± 44.3) g, 503.9 (± 46.11) cm3, 2.45 (±0.49) cm, 17.56 (±1.57) cm, 243.96 (±41.41) cm2, 55.14 (±4.93) cm. The average birth weight of baby and foeto-placental ratio were 2.55 (±0.25) kg and 4.97(±0.5) respectively in normal cases and 3.42 ± 0.26 kg and 5.91 ± 0.33 respectively in cases of diabetic pregnancy. Among the different parameters the birth weight of baby was the best predictor of the placental morphometric parameters while body weight and age of mother were poor predictors
