Chronic obstructive pulmonary disease (COPD) has no curative treatment, and in moderate to advanced stages, functional parameters and quality of life are affected. Lung volume reduction improves respiratory parameters and quality of life of these patients. Endoscopic lung volume reduction is a minimally invasive procedure that uses endobronchial valves or coils. Valves are unidirectional, blocking the air from entering the target lobe during inspiration, allowing the exit of air and secretions during expiration. Complete fissure and absence of collateral ventilation are needed for an adequate functioning of endobronchial valves. Endobronchial coils cause mechanical retraction of the lung parenchyma. We report two patients who underwent endoscopic lung volume reduction by endobronchial valves. One patient was on continuous positive pressure non-invasive ventilation due to his severe emphysema.
慢性阻塞性肺疾病（COPD）无法治愈，在中晚期，其功能参数和生活质量会受到影响。肺减容术可改善这些患者的呼吸参数和生活质量。内镜下肺减容术是一种微创手术，使用支气管内瓣膜或线圈。瓣膜是单向的，在吸气时阻止空气进入目标肺叶，在呼气时允许空气和分泌物排出。支气管内瓣膜充分发挥功能需要完整的肺裂和无侧支通气。支气管内线圈可导致肺实质机械性回缩。我们报告了两名接受支气管内瓣膜内镜下肺减容术的患者。其中一名患者因严重肺气肿接受持续气道正压无创通气。
