Nitinol stents have been used in the treatment of benign tracheal stenosis. A retrospective review of five patients treated at Stobhill Hospital over the last six and a half years is presented. Age at presentation ranged from 17 to 76 years. The minimum follow-up period was 23 months and the maximum was 78 months. All our patients were successfully decannulated, with none requiring recannulation. Four patients developed granulation tissue related to the stent at intervals ranging from three weeks to 41 months post stenting. Topical mitomycin C application has been useful after resection of granulations using the carbon dioxide (CO2) laser. Stent migration occurred in one patient three weeks after insertion. Nitinol stents are easy to insert and effective in the treatment of tracheal stenosis, but can have associated morbidity. Their use should be considered carefully, as insertion should be regarded as permanent. Publications reporting experience and outcome with the use of Nitinol stents in the trachea are reviewed.
镍钛诺支架已用于治疗良性气管狭窄。本文回顾性分析了过去六年半在斯托比希尔医院接受治疗的5例患者。就诊时年龄在17至76岁之间。最短随访期为23个月，最长为78个月。所有患者均成功拔管，无一例需要重新插管。4例患者在支架置入后3周-41个月期间出现与支架相关的肉芽组织。使用二氧化碳（CO2）激光切除肉芽后，局部应用丝裂霉素C有效。1例患者在支架置入3周后发生支架移位。镍钛诺支架易于置入，治疗气管狭窄有效，但可能伴有并发症。应谨慎考虑使用，因为支架置入应视为永久性的。本文还综述了有关镍钛诺支架在气管中应用的经验和结果的文献报道。
