A Study on Morphohistometric Changes of Placenta in Gestational Diabetes- A Comparative Analysis

Morphohistometric Changes of Placenta in Gestational Diabetes

Abstract

Introduction:The placenta is a complex fetal organ that fulfills pleotrophic roles during fetal growth. Placenta is the most accurate record of the infants prenatal experience. Gestational diabetes is much common than preexisting diabetes .i.e. it complicates 2% to 5% of pregnancies. It seems reasonable to expect that biochemical changes occurring in the pregnant women with diabetes should be reflected in the placental structure. Aim & objectives: In the present study an attempt is made to know the morphological changes of placenta in gestational diabetes mellitus.Subjects and Methods:In this study totally 60 placentae were studied, of which 30 were nondiabetic placentae and 30 from Gestational Diabetic mothers were studied macroscopically. Morphologically the shape, site of attachment of umbilical cord, central thickness of placenta was noted. Birth weight of the neonate and the placental ratio were also recorded. By using routine staining techniques and direct microscopy tissues of Gestational Diabetic placenta were studied qualitatively and compared them with normal placenta.Results:Our study demonstrates that there is a significant increase in weight and central thickness of placenta. Neonatal weight and placental ratio were also increased; there was no change in shape and site of attachment of umbilical cord in case of diabetic placenta when compared to normal. Conclusion:On the basis of results of present study it is concluded that diabetic placentae showed increase in weight and central thickness. Neonatal weight and placental ratio were also increased. These findings indicate that control of hyperglycemia only partially prevents the development of placental abnormalities.
