Persistent trigeminal artery or persistent primitive trigeminal artery (PTA) is the most common carotid-basilar anastomosis in both cadaveric and live patient studies, followed by persistent hypoglossal and persistent otic arteries. Approximately 0.2% of all angiographies reported this finding.
We present the case of a 21-year-old male who arrived at the emergency department with tonic‒clonic seizures. After performing diagnostic contrast magnetic resonance imaging and digital subtraction angiography, the patient was diagnosed with a right occipital arteriovenous malformations (AVM) fed by the right calcarine artery associated with an ipsilateral PTA. After considering surgical and endovascular treatment options, the patient was selected for watchful waiting. We included a literature review of the PTA, the results of a PubMed search regarding the combined presence of these findings, and a brief discussion providing insight into the implications for treatment.
Although several studies have linked PTA to different vascular pathologies, such as cerebral aneurysms, the association between PTA and AVMs remains scarce. This case, along with the literature review, shows that further research is needed to characterize the relationship between these findings.
在尸体和活体患者研究中，永存三叉动脉或原始永存三叉动脉（PTA）是最常见的颈基底动脉吻合，其次是舌下动脉和耳动脉永存。约 0.2%的所有血管造影报告了这一发现。
我们报告了一例 21 岁男性的病例，他因强直阵挛性发作到达急诊科。在进行诊断性对比磁共振成像和数字减影血管造影后，患者被诊断为右侧枕叶动静脉畸形（AVM），由右侧距状动脉供血，并伴有同侧 PTA。在考虑手术和血管内治疗方案后，患者选择了观察等待。我们对 PTA 进行了文献回顾，对 PubMed 搜索结果中关于这些发现联合存在的结果进行了综述，并进行了简要讨论，以深入了解治疗的意义。
尽管几项研究已经将 PTA 与不同的血管病理学联系起来，例如脑动脉瘤，但 PTA 与 AVM 之间的关联仍然很少。本病例以及文献回顾表明，需要进一步研究以确定这些发现之间的关系。
