Isolation of the subclavian artery is an unusual anomaly in which the subclavian artery arises not from the aortic arch but from a pulmonary artery via an arterial duct. Such isolation most often occurs with a right aortic arch, and in lesions frequently associated with a right arch, such as tetralogy of Fallot. Since 1994, we have undertaken surgery in four young infants with isolated subclavian arteries and unusual associated anomalies, including one with atrioventricular septal defect and common valvar orifice, two with interruption of a left aortic arch and one with interruption of a right aortic arch. In both patients with interrupted left arch, the isolated subclavian artery was diagnosed preoperatively by echocardiography. We emphasize the significant surgical issues.
锁骨下动脉离断是一种罕见的异常情况，即锁骨下动脉并非起源于主动脉弓，而是通过动脉导管起源于肺动脉。这种离断最常发生于右位主动脉弓，且常与右位主动脉弓相关的病变并存，如法洛四联症。自1994年以来，我们对4例患有锁骨下动脉离断及其他罕见相关异常的婴幼儿实施了手术，其中1例伴有房室间隔缺损和共同瓣膜口，2例伴有左位主动脉弓中断，1例伴有右位主动脉弓中断。在2例左位主动脉弓中断的患者中，术前通过超声心动图诊断出了锁骨下动脉离断。我们强调了重要的手术问题。
