Causes and Diagnoses
Causes and Diagnoses of Tracheal and Bronchial Stenosis
There are a number of causes of tracheal and bronchial stenosis, but the most common is prolonged intubation, or use of a breathing tube.
Other causes include:
- Congenital (present at birth)
- External injury to the throat
- Benign (noncancerous) or malignant (cancerous) tumor
- Lung transplant
- Inhaled chemicals
- Radiation therapy
- Autoimmune disease, including sarcoidosis
- Idiopathic (no reason found for the stenosis)
Diagnosing tracheal and bronchial stenosis
- X-ray: A chest X-ray can identify the presence of blockages or fluids creating pressure.
- Computed tomography (CT) scan: This test combines X-ray and computer technology to produce detailed cross-sectional images of your chest cavity.
- Bronchoscopy: An endoscope (a thin, flexible tube with a light and camera on the end) is inserted into your airway to check for blockages.
- Bronchoscope biopsy: An endoscope is inserted into your airway and tiny instruments are used to take a biopsy (small tissue sample) for testing.
