摘要
目的 :评价螺旋CT仿真内窥镜对儿童气道异物的诊断价值及急诊处理的意义。方法 :40例气管支气管非金属异物患者均进行了螺旋CT及仿真内窥镜检查 ,并经纤维支气管镜取出。其方法 :将螺旋CT容积扫描的图像数据传输到独立工作站 ,利用仿真内窥镜的软件功能重建为三维支气管图像。通过鼠标和键盘的操作使光标进入气管腔进而进入支气管腔内。结果 :40例患者中 ,气管异物 8例 ,右主支气管异物 2 3例 ,左主支气管异物 9例。仿真内窥镜表现为气道内结节者 2 4例 ,支气管阻塞 1 2例 ,假阴性 4例。结论 :CT仿真支气管内窥镜是一种安全无创的诊断方法 ;可以直观地显示异物的部位、大小、形态、数量及与支气管黏膜的关系 ,为纤支镜取出异物提供依据和更多的信息 ;可用于患者的复查 。
Objective:To evaluate the value of CT virtual bronchoscopy using the diagnosis of intracheal foreign body.Methods:Forty patients were examined with helical CT and CT virtual bronchoscopy. All were proved and extracted with fibreoptic bronchoscopy. The cross-sectional images were reconstructed to 3D tracheobronchial tree image rising endoscopy software and navigate or 'fly through' from trachea to subsegmental brouchus simulating fibreoptic bronchosopy.Results:Eight cases of intratracheal foreign body, 23 cases of right main bronchus and 9 cases of left main bronchus. CT bronchoscopy could reveal nodular(n=24) and obstruction(n=12). Conclusions: CT virtual bronchoscopy provides an safe and noninvasive diagnostic method. It could reveal the position,size,shape,quantity and the relationship with bronchial mucosa.lt can provide more diagnostic messages for fibreoptic bronchoscopy.
