[The radiological picture of the nonvascular surgical mediastinum].

A review was made of the chest X-ray features of 120 patients who underwent surgical treatment for mediastinal nonvascular pathologies over the past 12 years in the Mestre Hospital. A method of analysis is proposed which takes into account not only the differences between the immediate postoperative period and the follow-up, but also the anatomotopographic partition and the surgical practice. Normal and pathological patterns for both of the above periods are described. The "dimness" of the aerial tracheogram is emphasized as a useful and early sign of mediastinal recurrence.
