Abstract

The carotid duct (CD) is a transient embryological structure connecting the 3rd and 4th aortic arches. We found a persisting CD in an adult female case, by studying the computed tomography angiogram. On the left side, the proximal external carotid artery (ECA) agenesis was noted. The CD was inserted into the left subclavian artery and continued upwards to reach the level of the atlas, and then it descended to connect to a normally configured segment of that ECA. It could be speculated that the CD-to-ECA connection was possible via unregressed 1st and/or 2nd aortic arches. The segmental ECA agenesis is extremely rare, while its supply via a persisting patent CD was not reported previously to the authors' knowledge. The variants are extremely important during neck surgery because damaging the CD could determine hemorrhage, as well as ischemia in the ECA territory.

成人颈动脉导管和颈外动脉近端发育不全。
颈动脉导管(CD)是连接第 3 和第 4 主动脉弓的短暂胚胎结构。通过研究计算机断层扫描血管造影,我们在一名成年女性病例中发现了持续存在的 CD。左侧颈外动脉(ECA)近端发育不良。CD 插入左锁骨下动脉,继续向上到达寰椎水平,然后下降连接到该 ECA 的正常配置段。可以推测,CD到ECA的连接是通过未后退的第一和/或第二主动脉弓实现的。据作者所知,节段性 ECA 先天性缺损极为罕见,而通过持续通畅的 CD 供血的情况以前从未报道过。这些变异在颈部手术中极为重要,因为损伤 CD 可能会导致大出血以及 ECA 区域缺血。
