A new entity of right aortic arch with isolation of the left innominate artery is described in a three-day-old boy with complete endocardial cushion defect. Embryologically, this type of anomaly will result if the interruption of the embryonic left aortic arch occurs at two sites, one between the left ductus arteriosus and the descending aorta and the other between the ascending aorta and the left common carotid artery. Absence of pulse in the left arm and on the left side of the neck strongly suggests this anomaly. The aortogram and pulmonary arteriogram may confirm the diagnosis of this anomaly during life.
一名患有完全性心内膜垫缺损的3日龄男婴被描述为存在右位主动脉弓伴左无名动脉离断这一新型病变。从胚胎学角度来看，如果胚胎期左主动脉弓在两个部位发生中断，一处在左动脉导管与降主动脉之间，另一处在升主动脉与左颈总动脉之间，就会导致这种类型的异常。左臂和左侧颈部无脉搏强烈提示这一异常。主动脉造影和肺动脉造影可在患儿生前确诊这一异常。
