目的：探讨多排螺旋CT（MSCT）在诊断儿童血管环合并气道异常的价值。方法回顾性分析经手术确诊为血管环畸形159例患儿的CT影像资料。患儿均行多平面重组（MPR）、最大密度投影（MIP）及最小密度投影（MinIP），并观察血管环与气道的关系。结果159例患儿的血管环畸形包括右弓、迷走左锁骨下动脉62例，肺动脉吊带46例，双主动脉弓35例，左弓右降16例。159例患儿中血管环伴气道狭窄101例，其中主气道狭窄79例，左主支气管狭窄14例，右主支气管狭窄8例；气管桥14例；气管性支气管11例；对称性支气管2例。结论血管环常引起气道受压变窄及发育异常，MSCT可以清晰的显示血管环的组成及与气道的关系，为手术及合理治疗提供帮助。

Objective To explore the value of multislice computed tomography (MSCT) in diagnosis of vascular rings associated airway abnormalities in children. Methods CT image data were retrospective analysis in 159 cases of vascular rings, including multiplanar reconstruction (MPR), maximum and minimum density project reconstructions. The relationship between the vascular rings and airway had been observed. Results Of 159 cases of vascular rings as-sociated with airway stenosis in 101 cases, the main airway stenosis in 79 cases, left main bronchial stenosis in 14 cas-es, right main bronchus in 8 cases, tracheal bridge in 14 cases, tracheal bronchial in 11 cases, symmetry bronchial in 2 cases. Conclusions Vascular ring often causes compression of airway narrow and dysplasia. MSCT can clearly display vascular rings and its relationship with airway, providing help for surgical and reasonable treatment.
