Bronchoscopic Lung Volume Reduction.

Area of Science:

• Pulmonary Medicine
• Interventional Pulmonology
• Respiratory Disease Research

Background:

• Lung volume reduction (LVR) emerged as a treatment for advanced obstructive lung disease following the National Emphysema Treatment Trial.
• Surgical LVR carries a high complication rate, prompting the development of less invasive alternatives.
• Bronchoscopic lung volume reduction (BLVR) has become a key area of research and clinical application.

Purpose of the Study:

• To review the current landscape of bronchoscopic lung volume reduction (BLVR) techniques.
• To highlight the primary devices used in BLVR: coils and endobronchial valves.
• To emphasize the importance of patient selection criteria for BLVR.

Main Methods:

• Review of current bronchoscopic lung volume reduction (BLVR) devices.
• Discussion of factors influencing device selection, including emphysema characteristics.
• Consideration of the role of collateral ventilation in treatment success.

Main Results:

• Coils and unidirectional endobronchial valves are leading BLVR alternatives.
• Patient-specific factors, such as emphysema type and collateral ventilation, dictate the optimal device choice.
• Expert evaluation is crucial for successful BLVR management.

Conclusions:

• Bronchoscopic lung volume reduction (BLVR) offers a viable alternative to surgical LVR for select patients.
• Careful assessment of emphysema and collateral ventilation is essential for choosing the appropriate BLVR device.
• Management at specialized interventional pulmonology centers improves outcomes for BLVR patients.
