Tracheal perforation. A complication associated with transtracheal oxygen therapy.
A 73-year-old woman with a transtracheal oxygen catheter in place developed sudden onset of respiratory distress and subcutaneous emphysema. Bronchoscopy revealed the presence of three posterior tracheal wall perforations and a blind pouch arising from one of the perforations. Subsequent bronchoscopies revealed complete healing of the perforations. We believe that these perforations occurred during placement of the transtracheal catheter.
