“…Also, disproportionately large placenta could reflect an acute placental injury resulting in villous oedema or a chronic process requiring placental overgrowth, such as maternal anaemia, impaired glucose tolerance and malnutrition [1,24]. Infants with such abnormal ratios are at increased risk of perinatal death and intrauterine growth restriction [25,26].…”

Background: Placenta is a vital feto-maternal organ for promoting pregnancy, foetal growth and development. Placenta varies in weight, size, thickness, form and consistency. The weight of the placenta is functionally significant because it is related to villous surface area and foetal metabolism. Gross examination of placenta after delivery may provide a useful insight into foetal weight, newborn and maternal complications of pregnancy. Objectives: To determine the mean placental weight in our environment and also, to determine the correlation between the placental weight and neonatal outcome in term pregnancies in Calabar. Materials and Methods: This was a cross-sectional study of 300 women conducted at University of Calabar Teaching Hospital (UCTH). Participants in the study were women with singleton pregnancies who delivered either by vaginal delivery or caesarean section at term. Examination and weighing of placenta were done at delivery for placental weight. Foetal outcome that were recorded included birth weight, sex, length of the newborn and Apgar score at 5th minute. Maternal age, marital status and parity were also obtained. Data obtained were analyzed using the statistical package for Social Sciences (SPSS) version 20. Level of significance was set at p-value less than 0.05. Data were presented in tables and graph. Results: The mean placental weight was 652 ±152g and ranged from 250g-1,200g. The mean foetal birth weight was 3.309 ±0.522kg and ranged from 2.0-5.9kg. The mean placental weight to birth weight ratio was 1: 5.08. The mean gestational age at delivery was 38.94 ±1.33weeks while the mean length of the neonate was 49.79 ±2.66cm. There was a corresponding increase in placental weight with increase in neonatal birth weight and length of the neonate. Conclusions: Placental weight was positively correlated with birth weight and length of the neonate. Critical examination and weighting of the placenta immediately after delivery should be done to determine the well being of the newborn.

Introduction. Complications of pregnancy, which cause high perinatal morbidity and mortality, are accompanied by pathological changes in the placenta, namely, placental dysfunction (PD). 50.7% of PD are diagnosed in pregnant women with a low‐lying placenta (LLP). Aim. Тo study the pathomorphological parameters of placental dysfunction against the background of low placentation. Morphological and histometric features of the placenta from pregnant women with placental dysfunction (PD) against a background of low placental location were studied. The conducted studies show that the formation of placental dysfunction in pregnant women with a low location of the placenta is due to the violation of the physiological mechanisms of the formation of the feto-placental system in the first and second trimesters of gestation, as evidenced by: the predominance of the placenta of oval and anomalous forms (pleated, waist, with additional lobules ); the domination of the eccentric type of attachment of the umbilical cord and the main and intermediate types of branching of vessels. The manifestation of a positive type of compensatory-adaptive reactions at the organ level was a reduction in the thickness of the placenta in combination with an increase in the area of its maternal surface. A negative type of reaction in women with PD on a background of low placentation is a decrease in the volume of the placenta. At the tissue level in placentas from women with PD on a background of low placentation, compensatory-adaptive reactions were diagnosed in 70% of cases: a high percentage of terminal villi (69.4%), terminal villi with SCM (62.3%) and syncytial knots formation (29.5%), increased vascularization of villi (29.5%). In 25% of cases the degree of compensatory-adaptive reactions was significantly lower than in the control. Conclusions. In pregnant women with abnormal placentation, it is advisable to prevent the development of placental dysfunction from early gestation.
