One hundred one posteroanterior and 89 lateral chest radiographs were reviewed of patients with proven aberrant right subclavian artery. The patients were 17-96 years old. Three findings were noted on the posteroanterior radiograph: an oblique edge extending to the right from the aortic knob (60%); demonstration of the vessel through the lucency of the tracheal air column (43%) with sharp margins (29%) or as a tubular opacity without sharp margins (14%); and a "mass" effect at the medial right clavicular area (32%). Three findings were noted on the lateral radiograph: retrotracheal opacity (79%), aortic arch obscuration (62%), and posterior tracheal imprint (49%). Two of these findings (tubular opacity and mass effect) are reported as new observations in patients with aberrant right subclavian artery.
对101例经证实有迷走右锁骨下动脉患者的后前位胸片和89例侧位胸片进行了回顾。患者年龄在17至96岁之间。在后前位胸片上发现了三个征象：一条从主动脉结向右延伸的斜形边缘（60%）；通过气管气柱透亮区显示血管（43%），边缘清晰（29%）或呈边缘不清晰的管状致密影（14%）；以及右侧锁骨内侧区域的“肿块”效应（32%）。在侧位胸片上发现了三个征象：气管后致密影（79%）、主动脉弓模糊（62%）和气管后压迹（49%）。其中两个征象（管状致密影和肿块效应）在迷走右锁骨下动脉患者中被报告为新的观察结果。
