Aberrant origin of the right subclavian artery occurs in up to 1% of the population and can result in a wide range of symptoms. In this report, two cases of this anomaly are presented. In the first case, a patient developed fatal group A streptococcal aortitis. In the second case, the patient complained of chronic cough and intermittent dyspnea. The embryologic genesis of this abnormality is discussed and the current literature is summarized. Although relatively uncommon, it is important to consider this vascular anomaly in the differential diagnosis of patients with dysphagia, dyspnea, chest pain, fever, or mediastinal widening evidenced on chest roentgenography.
右锁骨下动脉异常起源在高达1%的人群中出现，可导致多种症状。在本报告中，介绍了两例这种异常情况。第一例中，一名患者发生了致命的A组链球菌性主动脉炎。第二例中，患者主诉慢性咳嗽和间歇性呼吸困难。讨论了这种异常的胚胎发生学并总结了当前文献。尽管相对不常见，但在对吞咽困难、呼吸困难、胸痛、发热或胸部X线检查显示纵隔增宽的患者进行鉴别诊断时，考虑这种血管异常很重要。
