The human placenta is considered as a mirror image of the neonate. The placenta provides an indirect link between the maternal circulation and that of the foetus and serves as the organ for exchange of materials through the process of diffusion. In evaluating the relationship between placental indices and neonatal outcome, a total of 236 placentae were obtained from the Kwame Nkrumah University of Science and Technology Hospital in Kumasi for this study. Placental indices measured were the placental weight, diameter and thickness whereas those of the neonates were Neonatal weight, head circumference and length. Mean placental indices for weight, diameter and thickness were 578.81 g, 17.40 cm and 2.04 cm respectively. The mean neonatal indices were 3.24 kg, 34.27 cm and 50.64 cm for weight, head circumference and length respectively. Neonatal weight correlated significantly with placental weight, neonatal length and neonatal head circumference. The strong correlation between neonatal weight and placental weight as well as placental volume suggests that the healthy development of the foetus depends on a healthy placenta. This study further affirms that the placenta should be critically examined in order to effectively monitor and manage adverse neonatal outcome.

“…Placentae with thickness lesser than 2.5 cms are found to be associated with intrauterine growth retardation and those with more thickness of 4 cms may be associated with maternal diabetes, fetal hydrops, and intrauterine fetal infections. [19] Elchalal et al, [20] determined that placental thickness during pregnancy above the 90th percentile was associated with a twofold risk of birth weight less than 2500 g. The thick placenta was also associated with birth weight above 4000 g. The risk for macrosomia in the thick placenta group was higher than in the control group.…”

Background: Placenta is an important connecting organ between the mother and fetus. It provides nutrition, gas exchange, waste removal, immune support, and endocrine functions. Since variations of the placenta result in effects on fetal development and neonatal survival it is the area of interest to be studied by anatomists, pathologists, and obstetricians. We in the current studied the placental morphology, variations, and abnormalities of the human placenta. Methods: The samples comprised of a collection of placentae in the Department of Anatomy of Prathima Institute of Medical Sciences, Karimnagar. Samples were collected after delivery, placentae were mopped to remove any clotted blood, and then weighed with 10 cm of the umbilical cord. The specimen is fixed in 10% formalin immediately over 24-48 hours and then subjected to thorough gross examination. Results: Out of n=60 placentae studied the mean weight of the placenta was found to be highest at 38 weeks of gestation with a mean surface area of 964.46 cm2 and mean weight of 463.75 Kgs. N=49(81.67%) were normal maternal conditions and history of abortions and pre-eclampsia was in n=2 cases each and oligohydramnios in n=3 cases. Among the fetal abnormalities Anencephaly, Macrostomia, MS/TS/Cerebellar hypoplasia, and holoprosencephaly with single nostril was found in n=1(1.67%) cases each. Conclusion: Examination of the placenta performed in the delivery room provides information that may be important to the care of both mother and infant. The findings of this assessment should be documented in the delivery records. The placenta should be submitted for pathologic evaluation if an abnormality is detected. Keywords: Placenta, Morphological Variations, Anencephaly, oligohydramnios, Macrostomia.

Background In recent years great attention has been focused on the structural and histological structures of the placenta and the umbilical cord due to their vital roles in fetal development and neonatal survival. While extensive studies have been documented in this area in the developed world, there is very little published information about the morphological variations that occur in human placenta in Sudan. Therefore, this study was designed to evaluate the structural variations in placental indices and its relation to neonatal outcome. Methods A prospective hospital - based study conducted in Wad Madani Maternity Teaching Hospital Department of Obstetrics and Gynecology between July 2014 and March 2018. Results Mean placental indices for weight, diameter and thickness were 515.51 g, 18.80 cm and 2.43 cm respectively. The mean neonatal indices were 2.95 kg, 33.19 cm and 44.42 cm for weight, head circumference and length respectively. Neonatal weight correlated significantly with placental weight, neonatal length and neonatal head circumference (P < 0.000). On the contrary, neonatal weight had no significant correlation with placental thickness and diameter Conclusion In this study, there was a strong relationship between the placenta and the fetus suggesting that the well-being of the fetus is highly dependent on the placenta since it serves as a link between the mother and the fetus.
