Potential hazards that may occur after implantation of airway stents include:

Potential hazards after implantation of airway stents include:

1. Stent Migration – The stent may shift from its original position, leading to airway obstruction or discomfort.

2. Granulation Tissue Formation – Excess tissue growth around the stent can cause airway narrowing and breathing difficulties.

3. Mucus Plugging – Accumulation of mucus within the stent may obstruct airflow.

4. Infection – Bacterial colonization or respiratory infections can occur around the stent.

5. Stent Fracture or Degradation – Over time, the stent material may break down, potentially leading to airway obstruction.

6. Airway Perforation or Erosion – The stent may damage the surrounding airway walls, leading to complications like bleeding or perforation.

7. Tracheoesophageal Fistula (TEF) – In rare cases, prolonged stent placement may create an abnormal connection between the airway and esophagus.

8. Persistent Coughing or Irritation – The presence of the stent may cause chronic cough or throat discomfort.

9. Difficult Stent Removal – Some stents become embedded in the airway tissue, making removal challenging.

Regular follow-up and airway monitoring are essential to manage these risks effectively.
