目的探讨儿童CT仿真支气管镜对可疑小儿支气管异物和支气管肺炎的鉴别诊断价值。方法回顾性分析29例反复咳嗽及发热、支气管异物不能排除的患儿资料,所有患者分别行CT仿真支气管镜(CTVB)检查,24h内行硬管支气管镜检查术。结果 29例中,CTVB检查发现支气管异物12例,支气管肺炎17例。除将痰痂1例、支气管内肉芽1例误为异物外,其它与硬管支气管镜检查均相符。结论 CTVB对鉴别小儿支气管异物和支气管肺炎有一定特异性,当胸部X线检查未提示异物存在,而临床表现显示有异物可能时,可考虑行CTVB检查,若亦未发现异物,不需再进行硬管支气管镜检查。
Objective To investigate the differential diagnosis of suspected bronchial foreign bodies and bronchial pneumonia in pediatric CT virtual bronchoscopy. Methods A retrospective analysis of 29 cases of repeated cough and fever, bronchial foreign body can not rule out the data of children, all patients were CT virtual bronchoscopy (CTVB) examination, 24h endoscopic bronchoscopy. Results In 29 cases, 12 cases of bronchial foreign bodies and 17 cases of bronchial pneumonia were found by CTVB examination. In addition to sputum scab in 1 case, 1 case of intrabronchial granulation mistaken for foreign body, the other with bronchoscopy were consistent. Conclusion CTVB has certain specificity in differentiating children with bronchial foreign body and bronchial pneumonia. When chest X-ray examination does not indicate the existence of foreign body, but CTXB may be considered when clinical manifestations show the possibility of foreign body, CTVB can be considered if no foreign body is found. Hard tube bronchoscopy.
