What are the causes of bronchiectasis?
Bronchiectasis is caused by conditions that predispose to chronic necrotizing infections and consequent destruction of muscle and elastic support tissue of bronchi and bronchioles. The most common conditions are: a. Bronchial obstruction (tumors; foreign bodies), diffuse obstructive airway diseases (atopic asthma; chronic bronchitis) b. Congenital or hereditary conditions (congenital bronchiectasis; cystic fibrosis) c. Necrotizing or suppurative pneumonias.
