A conventional TBNA needle (conventional transbronchial needle aspiration, cTBNA) is a single-use needle with a side hole, passed through the bronchoscope without ultrasound guidance. It takes tissue and secretion samples from large central lymph nodes and from lesions around the central airways. Bronchoscopy units can use it where no EBUS scope is available.

A conventional TBNA needle (transbronchial needle aspiration) for sampling of central airway and mediastinal lesions during bronchoscopy.
Conventional TBNA (cTBNA, transbronchial needle aspiration) uses a TBNA needle that passes through the bronchoscope and takes tissue and secretion samples through the airway wall, with no ultrasound guidance. EBUS-TBNA takes the same kind of sample under ultrasound.
Yes. Conventional TBNA is done with a bronchoscope alone. Large subcarinal and central nodes are sampled on anatomical landmarks, and peribronchial lesions seen on CT can be sampled as well.
Large subcarinal and central nodes, peribronchial lesions seen on CT, and paratracheal and peribronchial targets located on the Wang mapping points. It is also used to stage known lung cancer when the node is central and large.
Per the manufacturer's instructions for use: 20G, 21G and 22G, with a working length of 100 or 120 cm. There are metal sheath and Teflon sheath versions. The catheter diameter is matched to the working channel diameter of the bronchoscope.
Not yet. The conventional TBNA needle is not yet available for order in Türkiye, and the page lists it as Coming Soon. Write to us for the product documentation and the manufacturer's data.
Conventional TBNA is done with the bronchoscope alone and no ultrasound guidance. Large subcarinal and central nodes are sampled on anatomical landmarks, and peribronchial lesions seen on CT can be sampled as well. EBUS-TBNA is done with an EBUS bronchoscope and samples mediastinal and hilar lymph nodes under real-time ultrasound. The conventional needle has a side hole and comes in 20G, 21G and 22G; the EBUS needles of this range are 22G. The method follows the target and the equipment in the unit, and the choice is the physician's decision. The conventional TBNA needle is coming soon and cannot yet be ordered in Türkiye.
