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

Abstract

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.

Histomorphometric Variations of the Placenta in Normal and Hypertensive Pregnancies

“…Mehare et al and Goswami et al also reported decrease in FTP ratio in hypertensive groups compared to the normal placentae. 16,17 These findings are consistent with those observed in our study. This decline in FTP may be due to placental insufficiency associated with altered dimension of placental tissue, neonatal morbidity and ultimately with preterm deliveries.…”

“…13,15 A study by Goswami et al reported pregnancyinduced hypertension as an independent risk factor for causing low birth weight. 16 The mean fetoplacental weight ratio was decreased in the placentae of hypertensive group compared with their normal counterparts in the present study. Mehare et al and Goswami et al also reported decrease in FTP ratio in hypertensive groups compared to the normal placentae.…”

Fetoplacental Weight Relationship in Normal Pregnancy and Pregnancy Complicated by Pregnancy-Induced Hypertension and Abruption of Placenta among Mothers Who Gave Birth in Southern Ethiopia, 2018

“…Palaskar observed mean fetoplacental ratio in normal pregnancy was 5.8 and 7 : 1, and in PIH, the mean fetoplacental ratio was increased to 6.04. While Gunapriya in 2011 observed the fetoplacental ratio of 5.35 in normal and in PIH, 6.03 [19], Ananth observed in abruption of placenta mean birth weight and placental weight were lower especially in preterm births with placental ratio <10 th centile risk ratio 0.4, 95% CI 0.2-0.8 [20]. Several studies show reduced placental weight in abruption also a low birth weight of newborn, but the fetoplacental ratio was not calculated which was significant in our study.…”

Effects of Different Grades of Pih on Pregnancy Outcome

“…Navbir P found 2.16, 2.59 and 2.79 kg mean foetal weight in eclampsia, moderate and mild preeclampsia respectively [13]. Goswami P et al stated that during pregnancy, the placental mass maintains a dynamic relationship with the weight of developing foetus [8]. Shah RK commented that weight of placenta and birth weight are more decreased in preeclampsia with oedema than that without oedema but in severe preeclampsia both will be decreased probably due to marked proteinuria [18].…”
