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 ,避免反复纤支镜检查给患者带来更多的痛苦
Objective: To evaluate the diagnostic value of spiral CT virtual endoscopy in children with airway foreign bodies and the significance of emergency treatment. Methods: Forty patients with tracheobronchial non-metallic foreign bodies were examined by spiral CT and virtual endoscopy, and were removed by fiberoptic bronchoscopy. The method: the spiral CT volume scan image data transmitted to a separate workstation, the use of simulation software to reconstruct the endoscopic 3D bronchial image. Through the operation of the mouse and keyboard so that the cursor into the tracheal lumen and into the lumen. Results: Among the 40 patients, there were 8 cases of tracheal foreign body, 23 cases of right main bronchial foreign body and 9 cases of left main bronchial foreign body. There were 24 cases of endoscopic airway endoscopy, 12 cases of bronchial obstruction and 4 cases of false negative endoscopy. Conclusion: CT virtual bronchoscopy is a safe and noninvasive diagnostic method. It can directly display the location, size, shape, quantity and the relationship with the bronchial mucosa of foreign body to provide the basis and more information for the bronchoscopy to remove foreign body. ; Can be used for patient review, to avoid repeated fiberopticoscopy to patients with more pain
