Lung Volume Reduction Surgery (LVRS)

This procedure is performed after assessing suitable target areas of emphysema, and can be approached via thoracoscopy or open thoracotomy. Typically, under general anesthesia, overinflated diseased tissue is resected from the superficial or marginal areas of the lung, and the closure is reinforced with sutures, patches, or leak-sealing materials to improve elastic recoil and diaphragmatic movement. Postoperative respiratory, drainage, and pain monitoring are performed, with the goal of reducing hyperinflation and improving exercise tolerance. The above is general health information, not medical advice; specific details are subject to specialist evaluation and hospital protocols.
