Foeto-placental weight relationship in normal pregnancy and pregnancies complicated by pregnancy induced hypertension and abruption of placentae

Background The aim of this study was to study the effects of pregnancy induced hypertension and abruption of placenta on foeto-placental weight ratio and its comparison with normal group.

Methods In this comparative study hundred and twenty placentae were collected from labor room and gynecology operation theatre of Liaquat University hospital. Forty placentae from parturient that had pregnancy induced hypertension & forty placentae from parturient with history of Abruption of placenta & forty cases belonged to normal pregnancy (Control group). Fetal weights in all groups were taken along with the weights of placentae and foeto-placental weight was calculated in all groups.

Results Placental parameter weight and diameter of placenta in abruption of placentae and PIH group when compared with control group show highly significant (P <0.001) difference. The weight of the new born in abruption of placentae and PIH group also differs from control group significantly (P = 0.001). The feto-placental ratio is also significant statically in abruption of placentae but not in PIH.

Conclusion Both PIH and abruption of placentae are associated with remarkable changes in placenta such as small placental weight and diameter and as a result low birth weight babies and so altered feto-placental ratio.
