Syncytial Cell Surface of Placental Villi Associate with Obesity

In this work to describe the observations of syncytial cell surface in placental villi, in obese woman pregnancy of 92Kg, not associated to hypertension, with gain of 9Kg of weight during pregnancy has been the objective. The placenta was analyzed according to previous data obtained with light and scanning electron microscopy. Mature intermediate villi were seen with a diameter under the average normal diameter from 60 to 150um as indicated in the literature. They showed wrinkled cell surface, without bends in its longitudinal axis and scarcity of terminal villi. These also presented an average diameter minor when compared to the normal range of 30-80um.In immature intermediate villi globular extensions as blebs were seen collapsed and numerous elevations and depressions were found. In both intermediate villi as well as terminal villi scarcity of irregular microvilli was found. In this case not overgrowth in newborn was seen since the gestational weight gain correspond with their body mass index indicating that the syncytial placental membrane has regulated the transfer of gases and nutrients for the normal fetal development during obesity
