目的 探讨先天性支气管闭锁在 MSCT扫描的表现特征分析，旨在提高对该 病的诊断水平。方法 收集我院2014年1月 至2016年5月入院经支气管镜或手术病理 确诊的先天性支气管闭锁患者17例，分析 17例先天性支气管闭锁患者MSCT扫描图像 表现特点。结果 17例患者图像表现均出 现肺纹理稀疏，MSCT平扫轴位患者发育异 常侧肺野透光度增高，其中9例患者发生 于左肺，4例患者发生于左上肺，5例患者 发生于左下肺；8例患者发生于右肺，3例 患者发生于右上肺，5例患者发生于右中 下肺，14例患者可见肺气肿征象，3例患 者未见肺气肿。黏液栓附着于支气管呈 “树枝样”走形，15例患者为局限在一个 肺段改变，其12例伴行肺血管管腔变小， 肺血管分支减少。结论 先天性支气管闭 锁存在特征性MSCT图像表现，其MSCT扫描 图像能对先天性支气管闭锁患者图像征象 直观显示，根据图像特征可有利于对患者 进行准确诊断。

Objective To investigate the characteristics of congenital bronchial atresia in MSCT scan, and to improve the diagnosis of this disease. Methods 17 cases of congenital bronchial atresia diagnosed by bronchoscopy or surgical pathology were collected admitted to our hospital from January 2014 to May 2016. The characteristics of MSCT scan images were analyzed in 17 cases of congenital bronchial atresia. Results Patients showed sparse lung image and MSCT plain scan axial patients with abnormal development of lung field transmittance increased. 9 patients occurred in the left lung, 4 patients occurred in the left upper lung, 5 patients occurred in the left lower lung, 8 patients occurred in the right lung, 3 patients occurred in the right upper lung, 5 patients occurred in the right middle and lower lung, 14 patients showed signs of emphysema, 3 patients without emphysema. The mucous plug attached to the bronchus was a "branch-like" shape, 15 patients were confined to a lung segment change, the 12 cases associated with pulmonary vascular lumen smaller pulmonary vascular branch. Conclusion Congenital bronchial atresia showed characteristic MSCT images and its MSCT scan images can be signs of congenital bronchial atresia patients to visualize the image. It is helpful for the accurate diagnosis of patients according to the characteristics of the image.
