Treatment of airway stenosis with a customized bronchial stent using a three-dimensional printer and flexible filaments.

Stent placement is recommended for patients with airway stenosis. However, ready-made stents may be difficult to fit over lesioned areas. In the current case report, we describe the creation and placement of a custom stent in an 84-year-old woman with airway stenosis. We made a bronchial mould and customized stent with a three-dimensional printer and flexible filaments. This stent was able to successfully maintain our patient's airway patency.
