摘　　要：目的探讨双侧气管性支气管的临床及影像学表现。方法回顾性分析我院收治的2例双侧气管性支气管患儿的临床及影像学资料。结果例1为5个月女婴,生后即出现青紫;例2为4岁男性幼儿,生后出现青紫伴心脏杂音。MSCT最小密度投影重建显示2例患儿存在双侧气管性支气管,2例均脾缺如,均肝脏水平位,伴先心及大血管异常。结论气管性支气管是高于气管隆凸的支气管分支异位或多余,双侧均发生气管性支气管罕见。伴随无脾综合征患者的肺常呈双侧“右肺”,支气管也为双侧右侧支气管,有可能发生双侧气管性支气管。Objective The first report of bilateral tracheal bronchus in mainland of china. Methods More than 3000 children are performed by 16-row MSCT and done three- dimensional reconstruction on systemic and pulmonary vasculature and the tracheobronchial tree. Results Bilateral tracheal bronchus of the two patient is clearly demonstrated by MSCT Minimum intensity projection, the livers are all horizontal position, spleens are all absense, with congenital heart disease and great vessels anomalies. Conclusion Tracheal bronchus is a few seen ectopic or supernumerary bronchial branch usually arising from the right lateral tracheal wall just above the carina. Occurrence on the left side is far less common. And these two bilateral tracheal bronchus are seldom seen. In patients with Asplenia syndrome, the lungs are bilaterally“ right-sided”,and the bronchus are bilateral“ right- sided”bronchial branches. May be this bilateral tracheal bronchus can occur.
