A 45-year-old woman with recurrent dyspnea for 40 years was previously diagnosed with bronchial asthma and spasmodic dysphonia. On admission, the patient was diagnosed with expiratory central airway collapse (ECAC) due to expiratory dynamic airway collapse based on radiographic examination, chest computed tomography, and bronchoscopy. After continuous positive airway pressure and temporal airway stenting, surgical tracheobronchoplasty and tracheal membranous portion reinforcement using polypropylene mesh successfully relieved the respiratory symptoms. In patients with airway obstructive disease refractory to conventional therapies, ECAC should be considered.
一名有40年反复呼吸困难病史的45岁女性，此前被诊断为支气管哮喘和痉挛性发声障碍。入院时，根据影像学检查、胸部计算机断层扫描和支气管镜检查，该患者因呼气时动态气道塌陷被诊断为呼气性中央气道塌陷（ECAC）。在持续气道正压通气和临时性气道支架置入后，采用聚丙烯网片进行气管支气管成形术和气管膜部加固术成功缓解了呼吸症状。对于传统治疗难治的气道阻塞性疾病患者，应考虑ECAC。
