Conservative treatment of tracheal injuries.

Abstract

Tracheal injuries, independent of their origin, may be life-threatening. Surgical repair is regarded as the treatment of choice but has not been compared with other approaches. We hypothesized that defects bridgeable by an artificial airway may enable conservative treatment. We report on five patients with tracheal injuries, two in the trachea's upper third resulting from trauma and intubation and three in its middle third after percutaneous dilational tracheostomy. Tracheal defects were bridged by endotracheal or tracheostomy tubes under bronchoscopic guidance and the cuff was inflated distal to the lesion. Air leakage stopped immediately and all tracheal defects healed without further interventions. No case of stenosis or mediastinitis was observed. These results suggest that treating tracheal injuries conservatively by placing an artificial airway under bronchoscopic guidance may be effective and offers a convenient starting position for secondary surgical repair in selected patients when conservative treatment fails.
