Isolation of the left common carotid or left innominate artery from the aortic arch is rare. A six week malformed infant with a right aortic arch had isolation of a left innominate artery and connection to the pulmonary artery by a left ductus arteriosus. A right ductus arteriosus had been ligated. Another infant with a right aortic arch and ostium primum atrial septal defect was shown to have an aberrant left subclavian artery arising from the lower descending aorta. The left common carotid artery filled retrogradely and drained into the pulmonary artery by a left ductus arteriosus. This abnormality has not been reported before.
左颈总动脉或左无名动脉自主动脉弓分离的情况较为罕见。一名六周大的畸形婴儿，有右位主动脉弓，其左无名动脉分离，并通过左动脉导管与肺动脉相连。右动脉导管已被结扎。另一名有右位主动脉弓和原发孔房间隔缺损的婴儿，显示有一根异常的左锁骨下动脉发自降主动脉下部。左颈总动脉逆行充盈，并通过左动脉导管引流至肺动脉。这种异常情况此前尚未见报道。
