Although decreased bronchial cartilage is found in 50% of cases of congenital lobar emphysema (CLE), it can only be surmised that this defect produces a ball valve effect with consequent overinflation. We describe the flexible bronchoscopic features of CLE in a 3-year-old child. The observed airway patency during inspiration, and dynamic airway collapse on expiration suggests that bronchomalacia contributes to lung overinflation in these cases.
虽然在50%的先天性大叶性肺气肿（CLE）病例中发现支气管软骨减少，但只能推测这种缺陷会产生球阀效应，进而导致过度充气。我们描述了一名3岁儿童CLE的可弯曲支气管镜检查特征。吸气时观察到气道通畅，呼气时气道动态塌陷，这表明支气管软化在这些病例中导致了肺过度充气。
