The congenital anomaly of isolation of the subclavian artery, on the left side, is associated with a right aortic arch. The subclavian artery loses its connection with the aorta and is connected to the left pulmonary artery via the ligamentum arteriosum. Subclavian steal syndrome accompanies this anomaly in a minority of patients. We report 2 cases of adults with subclavian artery isolation, one of whom was symptomatic, and we discuss the importance of recognizing its presence.
左侧锁骨下动脉孤立的先天性异常与右位主动脉弓相关。锁骨下动脉与主动脉失去连接，并通过动脉导管与左肺动脉相连。少数患者会伴有锁骨下动脉盗血综合征。我们报告2例成人锁骨下动脉孤立病例，其中1例有症状，并讨论了认识其存在的重要性。
