Bronchiectasis is defined as irreversible dilation of the bronchial tree. Typically, the segmental and subsegmental bronchi become irregularly shaped and dilated, leading to a loss of the typical funnel configuration that allows smooth central flow of secretions. Additionally, ciliary activity in the area of the dilation is inadequate and further contributes to the difficulty in mobilizing secretions. The secretions become infected as they pool. The lower lobes, particularly the left lower lobe, are most frequently involved.
