AB Bronchiectasis  refers  to  irreversible  dilation  of  the  bronchi  or  bronchioles.  The  airway  enlargement  is  a  result  of  weakening  of  the  bronchial  walls  in  response  to  chronic  inflammation.  Impairment  of  the  mucus  transport  mechanism  contributes  to  the  formation  of  exudative  filling  of  the  dilated  bronchus.  Bacterial  colonization  of  the  abnormal  bronchus  leads  to  progressive  damage.
