Abstract

An abnormal origin of the vertebral artery from the common carotid artery (VA-CC) may occur on the right or left side with different embryonic mechanisms. We describe a patient with a double developmental anomaly, a right VA-CC and a right aortic arch. The rotation of the aortic arch caused a "twist" of the embryonic mechanisms of VA-CC and misdirected the differential diagnosis of the embryonic mechanisms at first glance. We discuss the pivotal points in differentiating the embryonic mechanisms of VA-CC.

摘要

椎动脉起源于颈总动脉(VA-CC)异常可发生在右侧或左侧,其胚胎机制各异。我们描述了一名患有双重发育异常的患者,即右侧VA-CC和右侧主动脉弓。主动脉弓的旋转导致了VA-CC胚胎机制的“扭曲”,乍一看误导了对胚胎机制的鉴别诊断。我们讨论了区分VA-CC胚胎机制的关键点。
