Objective Through the histopathological and morphometric evaluation of the umbilical cord, data can be obtained to support the IUGR and explain pathogenesis. With this study we aim to examine the relationship between the morphology of the umbilical cord and morphometric measurements of the umbilical cord vessels of normal newborns, and those of newborns with IUGR.
Method In this study, 98 umbilical cords of newborns were examined, 70 of which belonged to normal newborns, and 28 to newborns with IUGR. The anthropometric measurements of the newborns, their maternal features, the morphology of the placenta and the umbilical cord was recorded in addition to total cord area, Wharton’s jelly area, total vein area, and total artery area values for each umbilical cord.
Results The weight and the diameter of the placenta, the length of the umblical cord, the total cord area, and the area of the Wharton jelly are all related to the fetal growth. In addition to the above the total vascular area and the total arterial area are decreased in fetal growth retardation. Maternal age is also an important factor in the development of vascular structure.
Conclusion In light of these findings we can say that IUBG has many factors such as uteroplacental, maternal and environmental factors, however, the major factors arise as a result of the interaction between anthropometric measurements of the newborn and morphometric measurements of the umbilical cord.
