We administered Nd-YAG laser treatments in four patients aged 56 to 68 years for severe tracheal stenosis, the tracheal diameters varying between 2.5 and 5 mm. These patients were all dyspneic at rest with talking or dressing and their peak flows ranged from 8% to 36% of predicted. They were not felt to be candidates for surgical excision. Immediate palliative relief was achieved in all patients and lasted two to four months after a single treatment in three patients. One patient died three weeks after laser treatment due to respiratory failure from underlying emphysema. There were no complications of laser therapy. Postlaser therapy the tracheal diameter in each patient was at least 9 mm and peak flow improved to between 25% and 76% of predicted. The results suggest that laser treatment may be beneficial in cases of severe tracheal stenosis.
我们对4名年龄在56至68岁之间的严重气管狭窄患者进行了Nd-YAG激光治疗，气管直径在2.5至5毫米之间。这些患者在休息、交谈或穿衣时均有呼吸困难，其峰值流量为预测值的8%至36%。他们被认为不适合进行手术切除。所有患者均立即获得姑息性缓解，3名患者单次治疗后缓解持续了两至四个月。1名患者在激光治疗三周后因潜在肺气肿导致呼吸衰竭死亡。激光治疗没有并发症。激光治疗后，每位患者的气管直径至少为9毫米，峰值流量提高到预测值的25%至76%。结果表明，激光治疗可能对严重气管狭窄病例有益。
