An aortic arch extending into the neck is a rare congenital anaomaly. Left-sided cervical aortic arch was thought to be much less common than right-sided, but they are now almost equal in incidence in the published reports. This paper describes a case of left-sided cervical aortic arch in an adult, with a previously undescribed association, aneurysm of the descending thoracic aorta. Cervical aortic arch must be considered in the differential diagnosis of pulsatile cervical swellings. The embryological development of the aortic arch is discussed. This is still controversial and it is not possible to be sure of the embryological explanation of this congenital anomaly of the aortic arch from a study of the adult anatomy.
延伸至颈部的主动脉弓是一种罕见的先天性异常。左侧颈主动脉弓曾被认为比右侧少见得多，但在已发表的报告中，它们现在的发病率几乎相等。本文描述了一例成年患者的左侧颈主动脉弓病例，并伴有一种此前未描述过的关联情况，即胸降主动脉瘤。在搏动性颈部肿块的鉴别诊断中必须考虑颈主动脉弓。文中讨论了主动脉弓的胚胎发育。这仍然存在争议，仅通过对成人解剖结构的研究无法确定对这种主动脉弓先天性异常的胚胎学解释。
