Right aortic arch with isolation of the left subclavian artery is a rare anomaly. It has been reported to occur with conotruncal anomalies and may be associated with 22q11 deletion. Multidetector-row computed tomographic angiogram images of a 15-year-old African boy with Tetralogy of Fallot who had right aortic arch and isolated left subclavian artery arising from the left pulmonary artery by way of ductus arteriosus are presented.
右位主动脉弓伴左锁骨下动脉孤立是一种罕见的先天性畸形。据报道，它常与圆锥动脉干畸形同时出现，并且可能与22q11缺失有关。本文展示了一名15岁患有法洛四联症的非洲男孩的多排螺旋计算机断层血管造影图像，该男孩存在右位主动脉弓，其左锁骨下动脉通过动脉导管起源于左肺动脉。
