A 73-year-old woman with a transtracheal oxygen catheter in place deve
loped sudden onset of respiratory distress and subcutaneous emphysema.
Bronchoscopy revealed the presence of three posterior tracheal wall p
erforations and a blind pouch arising from one of the perforations. Su
bsequent bronchoscopies revealed complete healing of the perforations.
We believe that these perforations occurred during placement of the t
ranstracheal catheter.
