多层螺旋CT对小儿支气管桥的诊断价值

Value of Multi-slice CT for the Diagnosis of Pediatric Bridging Bronchus

[目的]探讨多层螺旋CT在小儿支气管桥中的应用价值.[方法]选择15例支气管桥患儿的临床影像学资料,分析其多层螺旋CT影像学特征.[结果]多层螺旋CT常规横断面显示14例（93.3%）,后处理气道重建显示15例（100%）;支气管桥的气管隆突显著高于正常隆突位置,而其中14例（93.3%）的桥支气管分叉位置位于T5、T6水平,低于正常隆突水平,且分叉夹角比较大.[结论]多层螺旋CT是支气管桥的最佳影像学诊断方法,值得临床推广.

[Objectivel To explore the diagnosis value of multi-slice CT（MDCT） for pediatric bridging bronchus. [MethodsI The clinical imaging materials of 15 children with bronchial bridge were chosen and the MDCT imaging features were analyzed. [ResultslThere were 14 cases（93.3 %） with conventional cross-sectional display of MDCT and 15 cases（100% ） with post-processing airway reconstruction. Bronchial bridge tracheal long axon was significantly higher than normal long axon position. Bridge bronchus dividing position in 14 patients（93.3%） located on T5 and T6 level and was below the normal long axon level with obvious larger bifurcation angle. [Conclusion] MDCT is the best imaging diagnostic method of bronchial bridge. Therefore it is worthy of clinical promotion.
