[Lymphatic afferents and efferents of lymph nodes of the Barety's space. Anatomic review in adults].

Lymph nodes of the Barety's space (LNLB) often involved in lung diseases are known under various names for a long time ago by pathologists. Our study involves 360 cadavers of adult subjects. The injection of a dye was performed by direct catheterization of a pulmonary segment. L.N.L.B. were directly or indirectly coloured (inter connected ganglionary network) more often from the lobes of the right lung, but from the lobes of the left lung too. From L.N.L.B. the lymphatic flow discharges in the venous confluent of the neck in the right side; in 1/4 of the cases a mediastinal efferent joints the left venous confluent too. From the lower lymph nodes of the space efferents can go to lymph nodes which are located right along the arch of the azygos vein (and then to the thoracic duct) and in the left side the group of left suprabronchial lymph nodes (then either to the thoracic duct in the mediastinum, or to the recurrent chain to the neck). At last, it seems that inside the lymph nodes themselves, lymphatic flows exist, the topography and the nature of which change according to the area interested by the injection.
