EBUS-TBNA
Pronunciation: EE-bus T-B-N-A
Also written as: EBUS-TBNA — Endobronchial Ultrasound-guided Transbronchial Needle Aspiration
Endobronchial ultrasound-guided transbronchial needle aspiration, a minimally invasive method for sampling mediastinal and hilar lymph nodes.
Full Definition
EBUS-TBNA combines real-time ultrasound imaging with fine needle aspiration to obtain tissue samples from lymph nodes and masses adjacent to the airways. This technique has revolutionized lung cancer staging by providing a safer alternative to mediastinoscopy for accessing mediastinal lymph nodes. The procedure is typically performed under conscious sedation and has high diagnostic yield for malignant disease.
Usage
Usage note: Always hyphenate TBNA when following EBUS. The acronym is widely used and acceptable in clinical documentation.
