Carbon dioxide capnothorax offers a safe method to protect the pleura during transthoracic needle biopsy (TTNB). This technique for pulmonary nodules resulted in diagnostic biopsies without complications.
Area of Science:
- Pulmonary Medicine
- Interventional Radiology
- Thoracic Surgery
Background:
- Transthoracic needle biopsy (TTNB) is a standard procedure for pulmonary nodules.
- Complications often arise from lung or visceral pleura traversal during TTNB.
Purpose of the Study:
- To evaluate the use of carbon dioxide to create a protective capnothorax during TTNB.
- To assess the safety and efficacy of this novel technique.
Main Methods:
- Five patients underwent TTNB with carbon dioxide capnothorax creation.
- Key parameters included target details, pleural distance, procedure length, CO2 volume, complications, and biopsy outcomes.
Main Results:
- Capnothorax induction was successful in all five patients.
- Carbon dioxide management varied: continuous infusion, spontaneous resolution, or aspiration.
- All biopsies were diagnostic, with no periprocedural or postprocedural complications.
Conclusions:
- Protective iatrogenic capnothorax using carbon dioxide is a safe and effective TTNB adjunct.
- Carbon dioxide's properties and availability make it a promising alternative to room air for this procedure.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
