Abstract

Removal of an expandable metal stem (EMS) from a narrowed tracheobronchial segment after long-term implantation is sometimes difficult. A 79-year-old woman with high risk post-intubation tracheal stenosis was treated with double Gianturco stems. The stems migrated and became fixed in the right main bronchus. Stenosis recurred in the original region causing dyspnea, coughing, and difficult expectoration. Four months later, she was successfully treated using a Nd:YAG laser to dilate the strictured tracheal lumen and remove the unnecessary part of the EMS by fragmentation. Therefore, in selected patients, Nd:YAG laser can be beneficial for removing EMSs.
