[Experience in the treatment of expiratory stenosis of the trachea and main bronchi].

In the period between 1970 and 1983 the authors had 242 patients (aged from 19 to 67) with expiratory stenosis of the trachea and main bronchi under observation. Complex bronchological examination was conducted with study of the mechanics of respiration at different levels of the tracheobronchial tree before and after treatment. The object of treatment was to arrest the inflammatory process in the tracheobronchial tree, restore the tonus of the membranous part, and reduce intrathoracic pressure. Respiration was controlled in 28 patients by means of a special tube with dosed resistance during inspiration. The indications and contraindications for surgical management of expiratory stenosis were determined. The choice of the graft for stenosis correction is guided by the severity of expiratory stenosis.
