The innominate vein usually lies superior to the aorta: using a suprasternal approach and an injection of contrast in the left arm, it is the earliest and most cephalad structure to be opacified. The aortic arch, right pulmonary artery and left atrium lie respectively below it. This relationship of these four structures is constant in all arrangements of the great arteries, forming the basis of contrast echocardiographic identification of the great vessels in cases of transposition. A case is reported of an innominate vein, the first structure to be opacified, lying inferior to the aortic arch and above the right pulmonary artery. This anomaly seems to be very rare.
采用胸骨上入路并向左臂注射造影剂时，它是最早显影且位置最靠头端的结构。主动脉弓、右肺动脉和左心房分别位于其下方。在所有大动脉排列中，这四个结构的这种关系是恒定的，构成了大动脉转位病例中利用造影剂超声心动图识别大血管的基础。本文报道了一例无名静脉，它作为最早显影的结构，位于主动脉弓下方和右肺动脉上方。这种异常似乎非常罕见。
