An isolated left subclavian artery is a rare anomaly. We report a 9-month-old boy with an isolated left subclavian artery associated with tetralogy of Fallot and the right aortic arch. MRI and angiography show that the blood supply through the left subclavian artery was maintained by a large tortuous collateral artery from the abdominal aorta. This type of collateral artery structure is unique.
孤立性左锁骨下动脉是一种罕见的先天性畸形。我们报告一名9个月大的男孩,患有孤立性左锁骨下动脉,并伴有法洛四联症和右位主动脉弓。磁共振成像(MRI)和血管造影显示,左锁骨下动脉的血供由一条发自腹主动脉的粗大迂曲的侧支动脉维持。这种类型的侧支动脉结构较为独特。
