Endobronchial Valve (EBV)

This technique involves the bronchoscopic placement of one-way endobronchial valves, which can be performed after assessing suitable target lobes and, if necessary, completing collateral ventilation testing. Typically, under general anesthesia or sedation, the target bronchus is accessed via the airway, and valves are placed branch by branch, allowing exhalation but obstructing inhalation, thereby promoting collapse of the target area to reduce hyperinflation. Postoperative imaging and respiratory monitoring are performed, with a focus on pneumothorax, mucus plugs, and infection. The goal is to improve ventilation distribution and exercise tolerance. The above is general health information, not medical advice; specific details are subject to specialist evaluation and hospital protocols.
