EBUS-TBNA

EBUS-TBNA stands for Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration. It is a minimally invasive diagnostic procedure that combines bronchoscopy with ultrasound imaging to obtain tissue samples from structures near the airways, particularly the lungs and mediastinum. EBUS-TBNA is commonly used for the evaluation of mediastinal and hilar lymph nodes, as well as lung masses or lesions.

EBUS-TBNA PROCEDURE

Patient
Preparation:

  • The patient may receive local anesthesia to numb the throat.
  • Sedation may be administered for comfort.

Bronchoscopy:

A bronchoscope, a thin, flexible tube with a light and camera, is inserted through the nose or mouth and into the airways.

Ultrasound
Imaging:

  • EBUS allows real-time ultrasound imaging of the bronchial and surrounding structures.
  • The bronchoscopist navigates to the target area using the ultrasound images.

Needle
Aspiration:

  • A thin needle is advanced through the bronchoscope and guided by ultrasound to the target tissue.
  • The needle is used to aspirate (withdraw) small tissue samples from lymph nodes or lesions.

Diagnosis
Results:

  • Pathologists examine the tissue samples to determine the presence of abnormalities, such as cancer cells, infections, or inflammatory conditions.
