Posterior tracheopexy, performed most often for intrinsic tracheomalacia, is a procedure that is gaining in popularity and application. In this procedure, pledgeted sutures are placed between the trachea and a more fixed structure, in order to provide the airway with greater patency. Polytetrafluoroethylene pledgets are readily available but risk migration into adjacent structures over time. We present a case of a pledget migrating in to the airway and presenting as an obstructing lesion that has required multiple repeat interventions. Given that bioabsorbable materials are available, surgeons should consider alternative pledgets for these patients.

气管固定术中使用聚四氟乙烯纱布的风险

后部气管固定术最常用于治疗内在性气管软化症，是一种越来越受欢迎和应用的手术。在此过程中，在气管和更固定的结构之间放置了脱脂缝线，以便为气道提供更大的通畅性。聚四氟乙烯纱布很容易获得，但随着时间的推移可能会迁移到相邻的结构中。我们展示了一个棉布进入气道并表现为阻塞性病变的案例，需要多次重复干预。鉴于有生物可吸收材料可用，外科医生应考虑为这些患者使用替代纱布。
