摘要
目的探讨胸透、胸片和MSCT检查诊断小儿气道透X线异物的临床应用价值。方法收集气道异物患者63例,其中MSCT重建检查55例,胸透43例,胸片21例(部分患者有2项或3项检查),回顾性分析3种检查方法诊断气道透X线异物的价值。所有患者均经纤维支气管镜手术证实。结果63例患者共67处异物,MSCT发现66处(98.5%),胸透、胸片均不能准确显示异物解剖位置,结合间接征象,MSCT、胸透和胸片的诊断准确率分别为100.0%、88.0%(38/43)、76.0%(16/21)。结论胸透是小儿气道异物的首选筛检方法,标准呼吸双相胸片的摄取有一定难度,MSCT重建应作为术前常规检查,对有明确异物吸入史的患者可直接做MSCT重建检查。
[Objective] To discuss the clinical application value of chest fluoroscopy, radiography and MSCT in transparent foreign body of trachea and bronchus in children.[Methods] 63 cases with transparent foreign body of trachea and bronchus were examined using chest fluoroscopy, radiography and MSCT, and their clinical application value were retrospectively analysed comparatively. All cases were confirmed with fiberoptic bronchoscopy. [Result] There are 67 foreign bodies in 63 cases. 66 foreign bodies were found by MSCT（98.5%）. Chest fluoroscopy and radiography cannot show the anatomical position of foreign bodies. Combinating with indirect signs, the diagnositic accurate rate of MSCT, chest fluoroscopy and radiography is 100.0%,88.0% and 76.0% respectively. [Conclusion] Chest fluoroscopy is the first choice to screen transparent foreign body of trachea and bronchus in children. It is difficulty to obtain typical chest radiography of inhale and exhale. MSCT should be routine examination before operation, perhaps it should be done directly for the children with clear history of inhaling foreign body.
