儿童血管环畸形伴气道狭窄的CTA表现

CTA Findings of Vascular Ring Anomalies With Airway Stenosis in Children

目的总结儿童心血管异常伴气道狭窄的CTA表现。方法收集2015年3月-2018年2月经支气管镜检查证实或怀疑血管环行CT检查发现的气道狭窄25例,均行CTA检查,分析其原始图像及工作站后处理图像,总结其心血管异常及气道狭窄表现。结果25例中,心血管异常方面,双主动脉弓6例,肺动脉吊带6例,右位主动脉弓并食管后左锁骨下动脉2例,头臂干压迫3例,肺动脉压迫5例,无明显血管异常压迫2例,其它因素1例。气道狭窄方面,气管至主支气管范围狭窄20例,主支气管至以下气道狭窄5例。结论CTA及后处理技术能较准确显示多种血管畸形及其伴随的气道狭窄,对病因诊断、外科治疗具有重要作用。

Objective To summary the findings of CTA in diagnosing cardiovascular anomalies associated with airway stenosis in children.Methods CTA was performed in 25 patients who suffered from airway stenosis confirmed by bronchoscopy and NECT to determine the relationship of the cardiovascular anomalies and airway stenosis from March 2015 to February 2018.Results Among 25 cases,about cardiovascular anomalies,double aortic arch in 6 cases,pulmonary artery sling in 6 cases,right aortic arch with left retroesophageal subclavian artery in 2 cases,Brachiocephalic artery compression in 3 cases,pulmonary artery compression found in 5 cases,no vascular anomaly finding in 2 cases,other causes in 1 case.On airways stenosis,tracheal to bronchial stenosis in 20 cases,bronchus to distal stenosis in 5 cases.Conclusion Various cardiovascular anomalies associated with airway stenosis can be evaluated by CTA and relevant post-processing technique,which is helpful for their etiology and surgery planning.
