title: [The formation of definitive variants in the organization of the rudimentary portion of the thoracic duct in the prenatal period of human ontogeny].
abstract: The aim of the investigation was to find out the anatomo-topographic parallels in the development of the initial part of the thoracic duct, organs of the abdominal cavity and branches of the abdominal aorta which takes place due to taxis of the physiological umbilical hernia and secondary adhesion of the peritoneum. Specificity of these processes determines variability of branching of the abdominal artery and the formation of the duodenum, the increasing pressure to the posterior wall of the abdomen and mesentery where the presumptive lymph collectors are found. The degree of their separation by invaginations of blood vessels, the rate and spread of the development of lymph nodes are responsible for the structure and position of the initial part of the thoracic duct in human fetuses. The results obtained may be taken as a morphogenetic ground for search of the local reference points for the initial part of the thoracic duct.
