目的 探讨螺旋CT和心脏彩超 对新生儿先天性血管环的诊断价值。方 法 回顾性分析2006年1月-2012年1月我 院收治的40例患有先天性血管环的新生 儿的临床资料，所有患儿均接受64层螺 旋CT(Multi-slicespiral CT, MSCT)、 心脏彩超(transthoracicechocardiogra phy,TTE)检查，所有患者均经手术证实为 先天性血管环。将MSCT、TTE的诊断结果 与手术诊断结果进行比较，观察并比较 MSCT和TTE检查对先天性血管环的确诊率 以及对合并心脏畸形、气管狭窄、食管狭 窄的确诊情况。结果 TTE和MSCT对先天性 血管环的确诊率分别为65.0%、92.5%， TTE的确诊率明显低于MSCT和手术证实 结果，比较存在较大的差异(χ2 =9.04、 16.97,P<0.05)；而MSCT检查对先天性 血管环的确诊率和手术证实结果相近 (P>0.05)。MSCT对先天性血管环合并心脏 畸形、气管狭窄、食管狭窄的诊断准确率 分别为40.0%、75.0%、17.5%，明显高于 TTE检查的诊断准确率(χ2 =4.92、4.38、 5.00，P<0.05)，并与手术证实结果较为 相近(P>0.05)。结论 MSCT对先天性血管 环的诊断准确率较高，与手术诊断基本相 符，既能清晰显示血管环的组成，还能明 确出血管环与毗邻结构的关系，可联合 TTE检查作为先天性血管环的有效诊断手 段，值得在临床上推广应用。

Objective To evaluate the diagnostic value of spiral CT and echocardiography of congenital vascular ring. Methods A retrospective analysis of January 2006 - January 2012 clinical data with congenital vascular rings of the 40 cases in our hospital, all patients underwent 64-slicespiral CT (Multi-slicespiral CT, MSCT), echocardiography (transthoracicechocardiography, TTE) examination, all patients were confirmed by surgery congenital vascular ring. The MSCT, TTE diagnosis and surgical diagnosis were compared, observed and compared MSCT and TTE examination of congenital vascular rings diagnosis rate and the combined cardiac malformations, tracheal stenosis, esophageal stenosis diagnosed cases. Results TTE and MSCT diagnosis of congenital vascular ring rates were 65.0%, 92.5%, TTE diagnosis and surgery was significantly lower than MSCT confirm the results, there is a big difference in comparison (χ2 =9.04,16.97, P<0.05), and MSCT examination of congenital vascular rings and surgically confirmed diagnosis rate were similar (P>0.05). MSCT congenital vascular rings with cardiac malformation, tracheal stenosis, esophageal stenosis diagnostic accuracy rates were 40.0%, 75.0%, 17.5%, significantly higher than the diagnostic accuracy of TTE examination (χ2 = 4.92,4.38,5.00, P<0.05), and the surgery to confirm the results more similar (P>0.05). Conclusion MSCT diagnosis of congenital vascular ring high accuracy, is basically consistent with the surgical diagnosis, both clearly shows the composition of vascular rings, but also clear the relationship between vascular rings and adjacent structures, can be combined as a congenital vascular TTE examination effective diagnostic tool ring, worthy of clinical application.
