The primitive hypoglossal artery is one of four embryonic anastomoses between the carotid and basilar arterial systems. The so-called persistent hypoglossal artery is most likely a complex vessel comprised proximally of a persistent hypoglossal artery and distally of components of the primitive lateral basilar-vertebral anastomotic network. This is the sixth reported case of an aneurysm of the persistent hypoglossal artery, and it is unique in its association with two supratentorial aneuryms, one of which had ruptured. All three aneurysms were treated by a direct surgical approach (two operations). Review of the other published cases demonstrates that these aneurysms arise at the junction of the persistent hypoglossal with the basilar artery. Aneurysms of this vessel require direct surgical treatment, because the parent vessel is functionally the only artery supplying the brain stem and therefore may not be ligated. The aneurysms usually lie in the subarachnoid space, indenting the brain stem, and may be approached through a suboccipital craniectomy.
原始舌下动脉是颈动脉和基底动脉系统之间四个胚胎期吻合支之一。所谓的持续性舌下动脉很可能是一种复杂血管，其近端由持续性舌下动脉构成，远端由原始外侧基底-椎骨吻合网络的成分构成。这是第六例报道的持续性舌下动脉动脉瘤病例，其独特之处在于与两个幕上动脉瘤相关，其中一个已经破裂。所有三个动脉瘤均通过直接手术方法（两次手术）进行了治疗。对其他已发表病例的回顾表明，这些动脉瘤发生在持续性舌下动脉与基底动脉的交界处。该血管的动脉瘤需要直接手术治疗，因为供血血管在功能上是供应脑干的唯一动脉，因此不能结扎。动脉瘤通常位于蛛网膜下腔，压迫脑干，可通过枕下颅骨切除术进行处理。
