DISEASES OF THE RESPIRATORY SYSTEM : NARROWING OF THE TRACHEA AND BRONCHI (STENOSIS TRACHEAE ET BRONCHIORUJW) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
The closure or narrowing of the trachea or bronchi in contact with foreign bodies, lesions of the wall (diphtheria, infectious granuloma), compression from the outside (malignant neoplasms, goiter, thymus persistens, tumors of the mediastinum, tumors of lymph glands, aortic aneurysm). Narrowing may occur acutely or develop chronically.
In acute stenosis:
If the foreign body is not removed with coughing or medical intervention, death occurs from strangulation.
In partial stenosis develops slow deep breathing with a characteristic rasping breath (stridor). The abdominal wall, epigastric region, intercostal space, supraclavicular spaces retracted during inspiration. In the lungs develops more or less widespread atelectasis. Appears diminished breath and voice trembling. The mediastinum and heart shifted towards the affected side. Comes circulatory disorders. In further developing bronchiectasis; often joins putrid bronchitis and gangrene of the lung.
Narrowing of the trachea differs from narrowing of the larynx that at last the larynx during breathing moves up and down; stenosis of the trachea the larynx is stationary. The main difficulties are frequently encountered when addressing the question of the cause of compression of the trachea and bronchi. Large role played by bronchoscopy and radiography.
In most chronic cases negative.
Removal of foreign bodies, operative treatment. Specific treatment with tertiary processes. X-ray radiotherapy for tumors. Otherwise, symptomatic treatment.
