Long-term course of bronchiectasis and bronchiolitis obliterans as late complication of smoke inhalation

We describe the long-term course of a patient with bronchiectasis and bronchiolitis obliterans, both of which developed as late complications of a smoke inhalation injury. Sequential chest X-rays obtained during the observation period showed gradual progression of bronchiectasis from the saccular to the cystic type. Symptoms, spirometry and blood gas analysis, however, remained stable for 15 years. We believe that symptoms and physiological derangement were due mainly to bronchiolitis obliterans, and that once the pathophysiological condition had been established following the initial injury, it could be maintained by conservative medical management.
