bronchial brushing

bronchial brushing

A procedure in which cells from the mucosa of the upper airways—trachea, bronchi, bronchioles—are obtained for cytologic evaluation under direct bronchoscopic visualisation of suspicious mucosal lesions. Bronchial brushing specimens are used to establish a diagnosis of malignancy and have a high degree of accuracy, comparing favourably with the biopsy in confirming the presence of malignancy; if used with a protected brush catheter, the relatively uncontaminated material can be cultured for various organisms.
