目的介绍小儿先天性气管性支气管的分类及意义,探讨多层螺旋 CT(MSCT)在该病中的诊断价值。方法回顾性分析43例先天性气管性支气管患儿的计算机 X 线摄影(CR)、MSCT扫描影像资料,MSCT 肺部常规10 mm 层厚扫描,在16层 MSCT 机进行1.25 mm 层厚、1.25 mm 层间隔重组,获得最小密度投影(minIP)、容积重组(VR)、表面遮盖技术(SSD)、仿真支气管内镜(VB)图像,记录病变的部位及与周围组织的关系和伴发异常。结果 43例病变经 CT 后处理技术全部清晰显示,CT 横断面扫描显示37例,CR 仅显示1例;43例中38例有先天性心血管病变,40例为右侧气管性支气管,3例为双侧气管性支气管,共有9例伴随气道狭窄,2例气管插管过深引起右肺上叶节段性肺不张。结论 MSCT 对于诊断先天性气管性支气管,显示气道及其周围伴随组织有良好的价值。
Objective To introduce the classification and significance of congenital tracheal bronchi in children and explore the diagnostic value of multislice spiral CT (MSCT) in this disease. Methods The data of computer tomography (CT) and computed tomography (CT) in 43 children with congenital tracheal bronchitis were retrospectively analyzed. The thickness of MSCT was 10 mm. The thickness of the CTCT was 1.25 mm (MinIP), volume reorganization (VR), surface occlusion technique (SSD) and simulated bronchoscopy (VB) images were obtained through interlamellar reorganization. The relationship between lesions and surrounding tissues and the associated abnormalities were recorded. Results All the 43 lesions were clearly demonstrated by CT post-processing. CT scan showed 37 cases in CR and only 1 case in CR. Among the 43 cases, 38 cases had congenital cardiovascular disease, 40 cases had right tracheal bronchus, 3 cases For bilateral tracheal bronchi, a total of 9 cases accompanied by airway stenosis, 2 cases of tracheal intubation caused by excessive pulmonary atelectasis of the upper lobe. Conclusion MSCT has a good value in the diagnosis of congenital tracheal bronchi, which shows the airway and the surrounding tissues.
