This paper presents a case of a de novo unruptured anterior communicating aneurysm associated with a persistent primitive trigeminal artery. The patient was a 65-year-old female with tinitis, for whom computed tomography with contrast medium indicated right dural enhancement. Dural arteriovernous malformation was suspected and angiography was thus conducted. A right persistent primitive trigeminal artery was demonstrated but no aneurysm could be found. Six years later, magnetic resonance angiography indicated an aneurysm on the anterior communicating artery. It was subsequently removed by surgery. A persistent primitive artery is frequently found to accompany aneurysm but de novo aneurysm associated with such an artery does not appear in the literature to date. The authors emphasize the importance of follow-up angiography in cases of persistent primitive artery not accompanied by an aneurysm.
本文介绍了一例与持续性原始三叉动脉相关的新发未破裂前交通动脉瘤病例。患者为一名65岁患有耳鸣的女性，增强计算机断层扫描显示右侧硬脑膜强化。怀疑为硬脑膜动静脉畸形，因此进行了血管造影。结果显示右侧存在持续性原始三叉动脉，但未发现动脉瘤。六年后，磁共振血管造影显示前交通动脉有一个动脉瘤。随后通过手术将其切除。持续性原始动脉常伴有动脉瘤，但迄今为止文献中尚未出现与这种动脉相关的新发动脉瘤。作者强调了在未伴有动脉瘤的持续性原始动脉病例中进行随访血管造影的重要性。
