MORPHOFUNCTIONAL FEATURES OF THE TERMINAL PART OF THE THORACIC DUCT AND THE POSSIBILITY OF ITS DRAINAGE IN CASE OF CHOLESTASIS
A study was made of the terminal section of the thoracic duct and lymphovenous anastomosis in the corpses of 87 people aged 19 to 90 years. Possible errors and complications during drainage of the thoracic duct associated with the peculiarities of its structure are analyzed. The study revealed that the terminal part of the thoracic duct has individual topographic, anatomical, and histological features, manifested in a wide variety of forms of its structure. Peculiarities of the topography of the terminal part of the thoracic duct, due to the process of the lymphatic plexus backbone, can be used to develop approaches and methods for catheterization of the thoracic duct. Intraductal hypertension, which develops with liver pathology, is a consequence of the structural features of the venous section of the lymphovenous anastomosis and terminal lymphangion, since the ability to dilate is sharply limited by the stiffness of the wall of the lymphangion created by the venous skeleton. Thrombosis of artificial lymphovenous anastomoses to relieve intraductal hypertension is also explained by morphofunctional features of lymphovenous anastomosis.
