EBUS is a bronchoscopic technique that uses ultrasound to visualize structures within the airway wall, lung, and mediastinum. It uses radial or convex probes. Radial probes provide 360-degree images of the airway wall and surrounding structures at high definition but do not allow for real-time biopsy. Convex probes have a 90-degree angle of view and allow for real-time EBUS-guided biopsy. EBUS is used to diagnose and stage lung cancers and mediastinal masses and can guide procedures like airway stenting. It has advantages of being minimally invasive and having a high diagnostic yield.

2. • It is a bronchoscopic technique that uses
ultrasound to visualize structures (within the
airway wall, lung, and mediastinum) .
• Used to guide bronchoscopic sampling
EBUS

3. PROBES USED
• Radial probe (RP-EBUS)
• Convex probe (CP-EBUS)

4. RADIAL PROBE
• High definition, 360-degree images of the
airway wall and surrounding structures.
• visualize the layers of the airway wall in
greater detail.
• Real time biopsy – not possible.

6. CONVEX PROBE
• Angle of view is 90 degrees.
• Real-time EBUS-guided transbronchial needle
aspiration, sampling – possible .

8. CONVEX
• 360 degree view
• Real time sampling
not possible
• Higher resolution ;
localisation
Radial
• 90 degree view
• Possible
• LESS

9. Technique
• Consious sedation , GA , LA
• TBNA – 40MM
• Discharge if gag reflex comes back.

10. INDICATION
-diagnosing, staging, (NSCLC).
-mediastinal masses.
-pulmonary nodules.
-endobronchial or peribronchial lesions,
-can guide therapeutic procedures (eg, airway
stenting)
-depth of tumour invasion

11. CONTRAINDICATION
• Absolute contraindications - severe refractory
hypoxia.
• Specific contraindications - exacerbation of
asthma, COPD, severe PAH, MI ,CCF ,
arrythymia .- at risk of bleeding.

12. Complications
- Usually minor.
- Hemorrhage and Pneumothorax.
- Hypotension, arrhythmias.
