The persistent primitive trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Patients are usually asymptomatic and the persistent primitive trigeminal artery is commonly found incidentally on imaging. Rarely, they may present with symptoms of neurovascular conflict or cranial nerve compression syndromes as the artery may be intimately related to the cranial nerves. The basilar artery is often hypoplastic in this condition and blood supply to the posterior circulation is predominantly via the persistent primitive trigeminal artery. Recognizing the persistent primitive trigeminal artery is imperative as disease of the artery may result in ischemia of the posterior circulation. To date, there is no clear association between this artery and cerebral aneurysms. We present a rare case of a patient with a persistent primitive trigeminal artery and a concomitant cavernous carotid aneurysm together with a literature review.
持续性原始三叉动脉是最常见的持续性颈动脉 - 椎基底动脉吻合。患者通常无症状，持续性原始三叉动脉常在影像学检查时偶然发现。极少数情况下，患者可能出现神经血管冲突症状或颅神经压迫综合征，因为该动脉可能与颅神经关系密切。在此情况下，基底动脉常发育不全，后循环的血液供应主要通过持续性原始三叉动脉。认识持续性原始三叉动脉至关重要，因为该动脉疾病可能导致后循环缺血。迄今为止，此动脉与脑动脉瘤之间尚无明确关联。我们报告一例罕见病例，患者患有持续性原始三叉动脉并伴有海绵窦段颈内动脉瘤，同时进行文献复习。
