Abstract：
An 85-year-old woman with a history of diabetes mellitus became aware of motor weakness of the left lower extremity. Magnetic resonance imaging showed multiple small cerebral infarctions in the right corona radiata. Angiography revealed persistent primitive trigeminal artery (PPTA) originating from the right internal carotid artery (ICA) and connecting to basilar artery, and the right ICA occluded distal to PPTA. Collateral blood circulation had developed, and sufficient collateral blood flow was expected. From these findings, the right ICA was considered to show stenosis due to atherosclerotic changes before occlusion. Conservative treatment was conducted with the transoral administration of rivaroxaban. It is important to correctly diagnose the anatomy and existence of an anomalous vessel in a stroke patient, not only when endovascular treatment is planned, but also for conservative medical treatment. Rapid and accurate radiological examinations facilitate safe and effective treatment.
摘要：
一名有糖尿病病史的85岁女性意识到左下肢运动无力。磁共振成像显示右电晕辐射区多发小脑梗死。血管造影显示持续的原始三叉神经动脉（PPTA）起源于右颈内动脉（ICA）并连接至基底动脉，右ICA闭塞在PPTA远端。侧支血液循环已经发育，和足够的侧支血流预期。从这些发现中,右ICA被认为显示在闭塞前动脉粥样硬化改变所致的狭窄.采用利伐沙班经口给药进行保守治疗。正确诊断中风患者异常血管的解剖结构和存在非常重要，不仅在计划进行血管内治疗时，也用于保守治疗。快速准确的放射学检查有助于安全有效的治疗。
