What Is A Tracheal Stent?

A tracheal stent is a small mesh tube that is placed inside the windpipe (trachea) to help keep it open. Some key things to know about tracheal stents:

They are usually made of silicone, metal (usually stainless steel or nitinol), or hybrid materials.

Tracheal stents are typically placed via a minimally invasive procedure using a bronchoscope (thin, lighted tube). The doctor guides the stent into the trachea.

Reasons for stent placement include tracheal collapse or blockage due to cancer, stenosis (narrowing), trauma, or other diseases affecting the trachea.

The goals are to help maintain an open airway, relieve symptoms like shortness of breath, and in some cases help deliver drugs directly to the upper airway.

Stents need to be well-fitted to the trachea to be effective without causing other issues like tissue irritation. Regular checkups are needed to assess positioning.

Risks can include migration of the stent, inflammation, granulation tissue formation, and increased mucus production. But they generally help improve breathing when properly indicated.

So in summary, a tracheal stent is a tubular implant used to mechanically prop open the windpipe during breathing. It can provide helpful palliation for tracheal diseases.
