The authors report an adult individual found to have very unusual origins of additional left and right pericallosal arteries that are normally only branches of the anterior cerebral artery. These vessels both arose from the vertebrobasilar system. The right accessory pericallosal artery was found to originate from the ipsilateral posterior inferior cerebellar artery and the left accessory pericallosal artery was found to originate from the ipsilateral posterior cerebral artery. To our knowledge, this variation has not been previously reported. The embryological and surgical implications of this finding are discussed.
作者报告了一名成年个体，发现其左右胼周动脉的起源非常异常，这些动脉通常只是大脑前动脉的分支。而这些血管均起源于椎基底系统。发现右侧副胼周动脉起源于同侧小脑后下动脉，左侧副胼周动脉起源于同侧大脑后动脉。据我们所知，这种变异此前尚未有过报道。本文讨论了这一发现的胚胎学和手术学意义。
