Placenta develops and grows till 37th week of pregnancy.Any insult durings its development such as PIH, a disease unique to pregnancy not only affects maternal health but also affects the placental development which in turn jeopardize the fetal normalcy. Present study was carried out to know the effect of PIH on placental weight, fetal weight and fetoplacental weight ratio. A total of 100 placentae of which 50 placentae of normotensive (control group) and 50 placentae of hypertensive pregnancy (PIH group) were collected fresh from either the delivery room or operation theatre. Placentae were washed, dried and weighted. Fetus was also weighted on the same weighing machine. Fetoplacental weight ratio was calculated. It was found that the weight of placenta and weight of fetus were significantly decreased in PIH group as compared to control group. The mean Placental weight was found to be 439.8 grams in control group and 378.6 gram in PIH group. Fetal weight was also decreased significantly. The mean fetal weight in control group was 2677.6 grams and 2112.2 grams in PIH group. The study showed linear co relation between fetal weight and placental weight in control group and there was significant decrease in fetoplacental weight ratio in PIH group.
