Bronchiectasis is defined as localized irreversible dilatation of the bronchi ( IRREVERSIBLE , please keep this thing in mind).This results in airflow obstruction & impaired clearance of secretions.
Cystic bronchiectasis occurs secondary to mucuos plugged proximal airways & chronic respiratory infection.
