TBNA

Transbronchial needle aspiration is a procedure to obtain cellular material using a needle that is passed through the bronchial wall. It is used to obtain tissue from lung or hilar/mediastinal lesions that are in close proximity to the endobronchial tree. EBUS-TBNA is a minimally invasive technique that has become the procedure of choice for evaluation of mediastinal/hilar lymphadenopathy due to its excellent diagnostic accuracy in staging of lung cancer and evaluation of numerous other processes.
