| Abstract: | Tracheobronchial lymph nodes (TBLN) have been studied in 71 corpses of persons at different ages. The TBLN are revealed by means of polychromic injection of Gerota mass into the lung tissue, or directly into the lymph nodes revealed. The number of the inferior and superior (right and left) TBLN varies within a wide range. Longitudinal dimentions of the lymph nodes increase with age. A certain age dependence in topography of the inferior and superior TBLN is stated. In persons of mature and elderly age, dextrobronchial type in arrangement of the inferior TBLN is found more often, and at younger age periods--even type of their arrangement is specific. The right superior TBLN in newborns, children and adolescents possess an evenly concentrated type of localization, and at later age periods--dispersive and unevenly concentrated. The superior left TBLN in newborns and children are mainly situated in the TB angle area, in persons of mature and elderly age--on the lateral surface of the thoracic part of the trachea. The form of the TBLN depends on their localization. A certain relation is determined between the localization of the inferior TBLN and the number of the superior (right and left) TBLN. |
