L.info@eco-vector.com1504196243213151810202118102021Copyright © 2021, Eco-Vector2021<p>Clinical, radiological and pathological data of a number of authors testify to the frequent defeat of the lymph nodes of the mediastinum with cancer metastases (MN Goryunova, 1951; Ya. G. Dillon, 1947; BK Osipov, 1959, etc.). Anatomical works of Ruvier (1932), DA Zhdanov (1947) and others testify to broad afferent connections of bifurcation lymph nodes in normal conditions with the organs of the chest cavity. These factors create the possibility of lymphogenous metastasis of cancer of the lung and esophagus in the mediastinal lymph nodes, in particular, in the bifurcation.</p>Kazan Medical archiveКазанский медицинский архив
