Occurrence of cerebral ischemia in the posterior circulation as a result of severe internal carotid artery disease and persistent trigeminal artery is rare. An 81-year-old man with medical history of hypertension and ischemic stroke presented with dizziness, nausea, and mild dysarthria. Magnetic resonance imaging of the brain revealed acute infarcts in the left internal carotid artery territory. CT angiogram revealed a persistent trigeminal artery (PTA) and severe atherosclerosis. The patient developed new neurological symptoms and repeat imaging revealed new acute infarcts in the PTA distribution. After undergoing a left carotid endarterectomy with no complications, the patient was discharged to a skilled nursing facility with no recurrence of ischemic stroke. This case adds a rare complication of an infrequent vascular anomaly to the limited body of the literature.
严重颈内动脉疾病和永存三叉动脉导致后循环脑缺血的情况罕见。一名有高血压和缺血性中风病史的81岁男性出现头晕、恶心和轻度构音障碍。脑部磁共振成像显示左侧颈内动脉供血区急性梗死。CT血管造影显示永存三叉动脉（PTA）和严重动脉粥样硬化。患者出现新的神经症状，重复成像显示PTA分布区有新的急性梗死。在接受左侧颈动脉内膜剥脱术且无并发症后，患者出院至专业护理机构，缺血性中风未复发。该病例为有限的文献资料增添了一种罕见血管异常的罕见并发症。
