This report describes imaging in a patient with a unique unnamed carotid-basilar anastomosis, where the entry into the skull was via the jugular foramen. There were associated findings of absent right and hypoplastic left vertebral arteries and an aberrant right subclavian artery. We speculate that the persistent anastomosis is developmentally related to the jugular branch of the ascending pharyngeal artery. Clinical implications of the course via the jugular foramen are also discussed.
本报告描述了一名患有独特的无名颈动脉-基底动脉吻合的患者的影像学表现,其进入颅骨的途径是通过颈静脉孔。同时存在右侧椎动脉缺如和左侧椎动脉发育不全以及右侧锁骨下动脉异常的相关表现。我们推测这种持续存在的吻合在发育上与咽升动脉的颈静脉支有关。还讨论了经颈静脉孔走行的临床意义。
