Two cases of persistent anastomoses between the carotid and vertebrobasilar systems which have only once been previously reported are described. These are a proatlantal intersegmental artery which arises from the external carotid artery and a primitive trigeminal artery with direct anastomosis to the superior cerebellar artery. Angiographic criteria for differentiation of the proatlantal and more common hypoglossal arteries, as well as the rare persistent cervical intersegmental artery are also presented.
本文描述了两例颈动脉与椎基底动脉系统之间持续存在吻合的病例，此前仅有一次相关报道。这两例分别是起源于颈外动脉的寰椎前节段间动脉和与小脑上动脉直接吻合的原始三叉动脉。文中还介绍了寰椎前动脉与更常见的舌下动脉以及罕见的持续存在的颈节段间动脉的血管造影鉴别标准。
