Cystic Bronchiectasis
General Considerations
- Pathologic dilation of the proximal and medium sized airways from weakening or destruction of their walls
- Three major causes are: obstruction, infection and traction, the most common being infectious
- Bronchiectasis may occur when there is prolonged partial obstruction, e.g. slow- growing neoplasms, foreign bodies
- Infection produces bronchial wall obstruction and is most important cause of bronchiectasis
