In 80 Wistar rats by means of electroroentgenolymphography lymphatic pathways and thoracic duct have been studied, normal and after ligation of the latter in 1-3 days, 1 and 2-3 months. Contrasting of the thoracic duct in the control animals reveals its additional ducts, that run in parallel to the main collector and they get into it after a certain distance, as well as different time phases of filling the duct are noted. When the thoracic duct is ligated, in 1-3 days dilatation of the ductal cistern, contrasting of lymphatic vessels and nodes in other regions are observed. In 1 month of the experiment the thoracic duct cistern is poorly expressed in comparison with the early time. The contrast substance continues to get into the group of the lymph nodes in other regions. A network of anastomoses of lymphatic vessels is formed in the area of ligation. In 2-3 months, when the contrast substance continues to get retrogradely into other groups and regions of the lymph nodes, final restoration of the lymph-flow takes place at the expense of formation of collateral pathways.
