A severe complication after laser-induced damage to a transtracheal catheter during endoscopic laryngeal microsurgery.

UNLABELLED: Subcutaneous emphysema and pneumothorax is a rare and severe complication of percutaneous transtracheal jet ventilation, usually caused by obstruction of the upper airway or displacement of the tracheal catheter. Nevertheless, it is our preferred technique for endoscopic laryngeal laser surgery. We report a patient with acute subcutaneous emphysema and pneumothorax during laser surgery, caused by unobserved laser damage and discuss the associated risk factors. IMPLICATIONS: The percutaneous transtracheal jet ventilation for elective laryngeal laser surgery reduces the risk of airway fires and gives a free endoscopic operative field. This case report suggests that, even when using a teflon catheter, laser-induced damage with severe complications might occur.
