Abstract |
Laser ablation under bronchoscopic guidance was conducted on 2 patients with severe tracheal stenosis. Case 1 was a 57-year-old man admitted to our emergency unit because asphyxia. Bronchoscopy showed the lumen occluded at the bifurcation by tracheal cancer. Case 2 was a 62-year-old woman who underwent tracheostomy elsewhere for respiratory failure caused by a brain contusion and was treated for 3 months. After transfer to our emergency unit, bronchoscopy showed severe tracheal stenosis. Tracheoplasty conducted under bronchoscopy used a noncontact Nd:YAG laser at an output of 10-40 W and irradiation time of 1 second per shot. Total irradiation energy was 1700-1900 J. Percutaneous cardiopulmonary support was used during the laser procedure due to asphyxia. All procedures were completed satisfactorily and clinical symptoms improved dramatically in both cases. Laser tracheoplasty under bronchoscopic guidance treated severe stenosis safely and completely. Percutaneous cardiopulmonary support was very useful in preventing severe respiratory failure or asphyxia during this procedure.
