Abstract

Bronchiectasis is defined as the abnormal and permanent dilatation of one or more bronchi, most often secondary to an infectious process. Bronchiectasis can be categorized as a chronic obstructive pulmonary lung disease manifested by airways that are inflamed and easily collapsible, resulting in air flow obstruction and impaired clearance of secretions. Diagnosis is usually based on a compatible clinical history of daily viscid sputum production and characteristic findings on CT scans. Complications include recurrent pneumonia, empyema, pneumothorax, and lung abscess. Hemoptysis, although common, is rarely a cause of death. Amyloidosis and metastatic abscesses were real risks in the pre-antibiotic era but are rarely observed today.
