TY - CHAP M1 - Book, Section TI - Chronic Lung Disease, Genetic Abnormalities, and Systemic Disease A1 - Wells, Robert G. PY - 2015 T2 - Diagnostic Imaging of Infants and Children AB - Bronchiectasis refers to irreversible dilation of the bronchi or bronchioles. The airway enlargement is a result of weakening of the bronchial walls in response to chronic inflammation. Impairment of the mucus transport mechanism contributes to the formation of exudative filling of the dilated bronchus. Bacterial colonization of the abnormal bronchus leads to progressive damage.
