The risks of polytetrafluoroethylene pledget use in tracheopexy.

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.
