MORFOLOGPHICAL FEATURES OF THE STRUCTURE AND BLOOD SUPPLYIN NEWBORN UMBILICAL REGION

Abstract

Objective: the study revealed a number of peculiarities in the location of blood vessels performing diff erent functions, their intensive branching and anastomosis were noted as well as ongoing neoformation.Materials and Methods: we used classic histological, immunohistochemical, and morphometric methods to examine the vascular component of the umbilical region in 1-month-old infants. We identified the volume occupied by the blood circulation system in the upper and lower segments of the umbilical region.Results: the results of histological examination demonstrate prevalence of great vessel branches in the lower segment of the umbilical region. Relative volumes of all the blood vessels are also statistically significantly higher in the lower segments of the paraumbilical region. Th e presence of vascular components in the umbilical region is slightly higher (though not reliably statistically) in the lower left segment compared to the right segment.Conclusions: collected data can be taken into account in pediatric surgery to search for optimal section methods for the umbilical region in order to access the abdominal cavity.
