Abstract：
Airway involvement in relapsing polychondritis (RP) can often be debilitating and life threatening. Interventional procedures such as stenting can be useful to improve airway stenosis. This case was diagnosed with RP with a circumferential obstruction at the left main bronchus. We determined that a silicone airway stent would be placed. The silicone stent was removed after 22 months due to granulation tissue. After stent removal, bronchoscopic findings revealed a collapsing left main bronchus during exhalation, but airway patency was maintained during inhalation without any respiratory symptoms. In this case, bronchomalacia remained after stent removal. However, since there were no severe respiratory symptoms, we decided that stent replacement was unnecessary. In general, it is difficult to remove airway stents in severe tracheobronchomalacia; however, temporary stenting might be a useful procedure in cases with unilateral main bronchial stenosis.
摘要：
复发性多软骨炎（RP）的气道受累通常会使人衰弱并危及生命。诸如支架置入的介入程序可用于改善气道狭窄。该病例被诊断为RP，左主支气管周围阻塞。我们确定将放置硅胶气道支架。由于肉芽组织，22个月后取出硅胶支架。支架移除后,支气管镜检查结果显示呼气时左主支气管塌陷，但吸入过程中保持气道通畅,无任何呼吸道症状.在这种情况下,去除支架后仍保留支气管软化。然而,因为没有严重的呼吸道症状，我们认为没有必要更换支架.总的来说,在严重的气管支气管软化症中，很难移除气道支架；然而，在单侧主支气管狭窄的情况下，临时支架可能是一种有用的方法。
