Patho -Quiz Bronchiectasis & Cystic
Fibrosis and All Correct Answers.
What is Bronchiectasis - Answer Dilation & Distortion of the bronchi as a result of extensive
INFLAMATION and destruction of the
-bronchial wall cartilage
-blood vessels
- Elastic tissue
- smooth muscle components
what part of the lung lobes are most affected with bronchiectasis - Answer - The segments of
the LOWER lobes and SMALLER bronchi with LESS supporting cartilage
what are the Anatomical Alterations of Bronchiectasis ? - Answer - Bronchial wall Destruction
- Impairment of the Mucociliary clearance
- copious bronchial secreations
- *Often Foul smelling sputum b/c of secondary bacterial growth*
- Smooth muscle wall constriction ( b/c of bronchospasm)
- hyperinflation of the alveoli ( air trapping)
- atelectasis
- consolidation
- parenchymal fibrosis
- hemorrhage secondary to bronchial arterial erosion( HEMPOTYSIS)
What are the 3 types of BRONCHIOECTASIS ? - Answer - Varicose ( also called FUSIFORM)
- Cylindrical ( tubular )
- Cystic ( saccular)
Describe Varicose ( Fusiform) Bronchiectasis? - Answer - Bronchi are dilated and constricted
in a irregular fashion
, - distorted and bulbous shape
Describe Cylindrical Bronchiectasis ? - Answer - Bronchi are dilated and have a REGULAR
outline similar to a TUBE
Describe Cystic Bronchiectasis - Answer - Bronchi progressively increase in diameter until
they end up in large cyst like sacs in the lung
- *this form of bronchiectasis causes the MOST damage to the tracheobronchial tree *
- bronchial walls become composed of FIRBOUS tissue
Etiology ( causes of ) Bronchiectasis can be either .....? - Answer ACQUIERED OR INHERITED
( congenital)
How is Bronchiectasis "acquired"? - Answer - By repeated & Recurrent Respiratory infections
- Caused by obstructive bronchial tumors
- enlarged hilar lymph nodes
- aspirated foreign bodies
* resulting in distal bronchiectasis *
How is Inherited or congenital bronchiectasis usually acquired ? - Answer - Caused
SECONDARY to Cystic fibrosis
* CF causes 50% of bronchiectasis *
CF:
- causes mucucilliary mechanism impairment
- causes abundant thick mucus
- bronchial infection
