婴幼儿气管、支气管非金属异物的CT诊断价值

CT Diagnostic Value of Non-metallic Foreign Body in Trachea And Bronchus of Childiren

目的 :探讨婴幼儿气管支气管非金属异物的CT诊断价值。材料与方法 :32例年龄 1岁～ 3 5岁气管、支气管非金属异物患儿作CT扫描。 18例患儿有异物吸入史 ,部分患儿X线检查征象不够明确。结果 :32例异物分布 :气管异物 7例 ,右主支气管异物 18例 ,中间支气管异物 1例 ,左主支气管异物 6例 ,全部异物均经支气管镜取出 ,总计共 4 2小块非金属异物。CT检查征象 :①异物直接显示 15例。②局限性支气管阻塞 2 0例。③纵隔移位 10例 (4例纵隔双边影 )。④患侧肺气肿18例。结论 :CT检查可显示支气管非金属异物 ,局限性支气管阻塞对异物定位仍断有重要意义。

Purpose:To evaluate CT diagnostic value in children with non-metallic foreign bodies of trachea and bronchus.Materials and Methods:CT scan were done in 32 children aged from 1 year to 3 5 years with foreign bodies in trachea and bronchus.18 cases had history of foreign body aspiration,x-ray findings of partial patients were indefinite.Results:The distribution of foreign bodies in 32 patients included:7 cases in trachea,18 cases in right main bronchus,one case in middle bronchus,6 cases in left main bronchus.All foreign bodies well removed through bronchoscopy,total amount reached 42 small pieces of non-opaque foreign bodies.CT findings were as follows:①CT scan could show non-foreign body in 15 derectly.②Local bronchial obstruction in 20.③Shift of mediastinum in 10(4 of them reveal double margen signs)④Emphysema of affected side in 18.Conclusion:CT scan could reveal the situation of non-mellatic foreign body and local bronchial obstruction,It is of importantance in localized diagnosis of non-metallic bodies in airway.
