Isolation of the right subclavian artery (RSCA), defined as loss of continuity between the RSCA and aorta, is a rare anomaly and its association with dextrotransposition of great arteries (D-TGA) is exceedingly unusual. We present the case of a 5-day-old neonate with cyanosis from birth and a transthoracic echocardiographic diagnosis of D-TGA, where on computed tomography angiography, the RSCA was seen arising from the proximal part of the ipsilateral pulmonary artery via a patent right ductus arteriosus.
右锁骨下动脉离断（定义为右锁骨下动脉与主动脉之间连续性中断）是一种罕见的异常情况，其与大动脉右位转位（D-TGA）的关联极为罕见。我们报告一例5日龄新生儿病例，该患儿自出生即有发绀，经胸超声心动图诊断为D-TGA，在计算机断层血管造影检查中，可见右锁骨下动脉经未闭的动脉导管起自同侧肺动脉近端。
