摘　　要：目的:分析儿童先天性主动脉弓畸形的MSCT表现,提高对该病的认识及诊断水平。方法:回顾性分析经MSCT诊断的83例先天性主动脉弓畸形患儿的CT横轴面图像,并进行多平面重组(MPR)、最大密度投影(MIP)、最小密度投影(MinIP)、容积再现(VR)后处理。结果:83例中梗阻性先天性主动脉弓畸形22例,包括主动脉缩窄17例(合并迷走右锁骨下动脉4例),主动脉弓离断5例;非梗阻性先天性主动脉弓畸形61例,包括双主动脉弓8例,右位主动脉弓、右位降主动脉44例,右位主动脉弓伴迷走左锁骨下动脉7例,左位主动脉弓、右位降主动脉2例(合并迷走右锁骨下动脉1例)。结论:MSCT可清晰显示主动脉弓畸形及合并畸形,对诊断先天性主动脉弓畸形具有重要价值。Objective：To investigate the multi-slice CT characteristics of congenital aortic arch anomalies in children, in order to improve the understanding and diagnostic level of this disease.Methods：CT data of 83 cases with congenital aor-tic arch anomalies were analyzed retrospectively,and the images were reconstructed using multi-planar reconstruction （MPR）,maximum intensity projection （MIP）,minimum intensity projection （MinIP）and volume rendering （VR）.Results：Obstructive congenital aortic arch anomalies were observed in 22 cases,including 17 cases of coarctation of aorta （COA） （combined with aberrant right subclavian artery in 4 cases）,5 cases of interruption of aortic arch （IAA）.Non-obstructive congenital aortic arch anomalies were observed in 61 cases,including double aortic arch （DAA）in 8 cases,right aortic arch and right descending aorta in 44 cases,right aortic arch with aberrant left subclavian artery in 7 cases,left aortic arch and right descending aorta in 2 cases （combined with aberrant right subclavian artery in one case）.Conclusion：MSCT can clearly demonstrate the aortic arch anomalies and associated malformations and has important value for diagnosis of congenital aor-tic arch anomalies .
