Campomelic dysplasia is a generalized disorder of cartilaginous growth and development, leading to early death from pulmonary insufficiency. We describe the airway dynamics as observed bronchoscopically in two affected infants. Both infants demonstrated anatomic compromise of the upper airway and diffuse laryngotracheobronchomalacia. Additionally, both had a characteristically small, bell-shaped thoracic cage. The abnormal airway dynamics produced serious inspiratory and expiratory obstruction in these infants and, in combination with the restrictive chest wall defect, led rapidly to the development of respiratory failure. While palliative procedures such as tracheostomy may temporarily improve airway dynamics, future respiratory tract insults may prove fatal.
弯肢侏儒症是一种软骨生长和发育的全身性疾病,可导致因肺功能不全而早亡。我们描述了在两名患病婴儿中通过支气管镜观察到的气道动力学情况。两名婴儿均表现出上气道的解剖结构受损以及弥漫性喉气管支气管软化。此外,两人都有特征性的小而钟形的胸廓。异常的气道动力学在这些婴儿中产生了严重的吸气和呼气性梗阻,并与限制性胸壁缺陷相结合,迅速导致呼吸衰竭的发展。虽然诸如气管造口术等姑息性手术可能会暂时改善气道动力学,但未来的呼吸道损伤可能是致命的。
