Bronchiectasis

Bronchial dilatation (bronchiectasis) is characterized by local irreversible anatomical structural abnormalities of the bronchi. It is due to chronic purulent inflammation and fibrosis of the bronchi and its surrounding lung tissues, which destroys the muscles and elastic tissues of the bronchial wall, resulting in bronchial deformation and long-lasting expansion. Typical clinical symptoms are chronic cough, coughing of large amounts of purulent sputum, and repeated hemoptysis. The main causative factors are bronchial infection, obstruction and traction, and some are congenital. Patients often have a history of childhood measles, whooping cough or bronchopneumonia. With the improvement of people's life, the measles, pertussis vaccination, and the application of antibiotics have significantly reduced the disease.
