Problems of access to the umbilical vein through the liver parenchyma.

Abstract

The investigation of the development and structure of the branches of the umbilical vein (UV) and the portal hepatic vein (PHV) during human intrauterine development is vital for identifying the general principles of liver histogenesis. This research provides key insights into the processes shaping these structures, enhancing our understanding of congenital abnormalities and aiding in the advancement of prenatal diagnostics. 17 The aim of the study. This study aims to examine the topographical characteristics of the umbilical vein during the prefetal stage of human ontogenesis. Material and methods. This study utilized 12 prefetal samples. A comprehensive approach was applied, incorporating various morphological research methods. These included morphometry, the preparation and analysis of histological sections, both macro- and microscopic observations, as well as plain and thin dissections conducted under the MBS-10 microscope. Additionally, vessel injection followed by radiography was performed to enhance the depth and precision of the analysis.
