A new approach to the vascular-nervous correlations of the superior mediastinum in man.

The relationship between the superior mediastinal organs has been investigated in the adult and the newborn. It was found that this region could be represented by a geometrical schematization based on the correlations that exist among the vascular and nervous elements that lie on the right mediastinal wall. A vascular triangle, a vascular-nervous triangle and a retro-vagal square are described. The size of these forms and their relations with the organs they enclose varies depending on the build of the subject being examined in this area, particularly from a teaching point of view.
