16层螺旋CT在呼吸道异物诊断及术后随访中的应用价值

The value of 16-slice spiral CT in the diagnosis of airway foreign body and postoperative follow-up

目的:探讨多层螺旋CT(MSCT)对呼吸道异物的诊断价值及在术后随访中所具有的优势。方法:利用Siemens Sensation16螺旋CT对104例临床疑为呼吸道异物的患者进行胸部容积扫描,将原始数据传至工作站进行多平面重建(MPR)、容积重建(VR)及仿真内窥镜(CTVB)等多种技术相结合进行诊断,其中66例诊断为呼吸道异物,9例行MSCT随访。结果:66例中MSCT诊断8枚异物位于气管,右侧支气管及其分支为39枚,左侧支气管及其分支19枚。经临床支气管镜证实61例,其余5例:1例为黏液团,3例仅见脓液、未见明显成形异物,1例为炎性栓子。9例随访病例中发现2例异物未完全取出。结论:临床拟诊呼吸道异物时,由于MSCT无创、快捷、准确率高,在术前诊断及术后随访中可作为首选。

Objective：To explore the value of MSCT in the diagnosis of airway foreign body and the advantage of post-operative follow-up.Method：104 patients suspected of having foreign bodies aspiration were performed the chest volume scan using Siemens Sensation 16 MSCT.The original CT data scanned were reconstructed with MPR,CPR,VR and CTVE to demonstrate and diagnosis the airway foreign bodies by the workstation.66 cases were diagnosed as airway foreign bodies,9 cases were followed up by MSCT.Result：Among 66 cases foreign bodies,8 cases of trachea,39 cases of right bronchus,19 cases of left bronchial bronchus.61 cases foreign bodies were Confirmedconfirmed by bronchoscopy,but the remaining 5 cases：1 case of tracheal mucus,3 cases of pus,1 case of Inflammatoryinflammatory emboli.2 cases were imcompletelyincompletely removed among 9 following-up cases.Conclusion：MSCT was a non-invasive,effective and accurate method to display the airway foreign body.When patient was suspected foreign body,MSCT has advantages not only in diagnosis and preoperative selection of treatment,also in the postoperative follow-up.
