For surgical treatment of patients with tracheoesophageal fistulas the localization of the aortic arch is great practical importance. Aortography and CT scanning have been advocated as the radiographic techniques of choice. The location of the aortic arch can be diagnosed on a chest x-ray by the deviation of the trachea alone. A barium swallow is not required. The optimal radiographic technique for this purpose was investigated in phantom studies and tested in animals and newborns. It is proposed that in addition to the standard chest x-ray a high kvp film with hardened beam (1 mm copper -- 1 mm aluminum) be added in order to demonstrate the tracheal deviation. The additional x-ray exposure to the infant is negligible; and the technique is simple, reliable, and noninvasive.
对于气管食管瘘患者的手术治疗，主动脉弓的定位具有重大实际意义。主动脉造影和CT扫描一直被推荐为首选的影像学技术。仅通过气管的偏移就可以在胸部X光片上诊断主动脉弓的位置，无需进行钡餐检查。为此目的，在模型研究中对最佳影像学技术进行了研究，并在动物和新生儿中进行了测试。建议除标准胸部X光片外，增加一张使用硬化射线束（1毫米铜 - 1毫米铝）的高千伏胸片，以显示气管偏移。对婴儿额外的X射线照射可以忽略不计；而且该技术简单、可靠且无创。
