小儿气道透X线异物X线诊断误漏诊分析

Analysis of missed diagnosis or misdiagnosis of radiolucent foreign body in respiratory tract by radiography in children

目的 :旨在提高小儿气道透X线异物的X线诊断水平。方法 :回顾性分析 36例小儿气道透X线异物X线诊断 ,并与气管支气管镜结果对照 ,分析其误漏诊原因。结果 :误漏诊共 1 6例 ,其中支气管异物 4例 ,气管异物 7例 ,声门下异物 2例 ,异物性局限性支气管炎 3例。结论 :对于小儿气道异物病的X线诊断 ,良好的深呼、吸气相胸片及动态透视结合诊断至关重要。并应按支气管。

Objective:To improve X ray diagnostic accuracy of radiolucent foreign body in respiratory tract in children.Methods:X ray findings of tracheobronchial foreign body in 36 children,and the reasons of its missed diagnosis or misdiagnosis were retrospectively analyzed when compared with the findings by tracheobronchoscopy.Results:In 16 cases of missed diagnosis or misdiagnosis,4 cases were the foreign body in the bronchus, 7 cases intratracheal foreign body,2 cases subglottic foreign body,and 3 cases focal bronchitis secondary to the foreign body. Conclusion: Chest radiographs in deepbreath together with fluoroscopy play an important role in the diagnosis of the foreign body in children's respiratory tract. The following steps should be established in the diagnostic and differential diagnostic order of the foreign body in bronchus,trachea and subglottis.
