报告1例成人原发三叉动脉（PTA）永存尸检。在颈内动脉海绵窦部分PTA的起点处，PTA分支成脑膜垂体干和下海绵窦动脉。这可能表明这些动脉在同一胚胎阶段形成。在后颅窝的PTA池部分，它也分支到三叉神经根和脑桥通往基底动脉。即使在成人的情况下，PTA也可能具有正常结构的功能。PTA穿过Meckel's腔内侧的硬膜孔，与基底动脉相连。PTA的直径在孔处明显减小。硬膜孔可能是胚胎期PTA消退的部位。
An adult autopsy case of the persistent primitive trigeminal artery (PTA) is reported. At the origin of the PTA in the cavernous portion of the internal carotid artery, the PTA branched into the meningohypophyseal trunk and the artery of the inferior cavernous sinus. This might indicate that these arteries were formed at the same embryonic stage. At the cisternal portion of the PTA in the posterior fossa, it also branched into the trigeminal nerve root and pons on the way to the basilar artery. The PTA might have functions for the normal structures even in the case of adults. The PTA passed through the dural foramen, which was located medial to Meckel's cave, and connected with the basilar artery. The diameter of the PTA decreased markedly at the foramen. The dural foramen might be the site of regression of the PTA during the embryonic stage.
