Abstract：
Patients with a persistent primitive trigeminal artery frequently have a poorly developed vertebrobasilar arterial system. However, they are not at higher risk of stroke and most are asymptomatic. Left cerebral watershed infarction was identified in a 75-year-old man who presented with aphasia and disorientation on magnetic resonance image (MRI). Additional imaging studies also demonstrated a right persistent primitive trigeminal artery, aplastic basilar artery, and 47% left internal carotid artery stenosis. Antiplatelet medication was administered and he was discharged 2 weeks after admission on aspirin. At the 4-month follow-up, cerebral blood flow in the left watershed territory was still decreased; however, no recurrent stroke had occurred. Although the indication for surgical or endovascular intervention for internal carotid artery stenosis is primarily determined by the degree of stenosis, cerebral blood flow evaluation is recommended in patients with internal carotid artery stenosis and a persistent primitive trigeminal artery.
摘要：
患有持续性原始三叉神经动脉的患者通常具有发育不良的椎基底动脉系统。然而,他们没有更高的中风风险，大多数是无症状的。在一名75岁的男性中发现了左脑分水岭梗塞，该男性在磁共振图像（MRI）上表现出失语症和迷失方向。其他影像学研究还显示了右持续性原始三叉神经动脉，再生基底动脉,和47%的左颈内动脉狭窄。服用抗血小板药物，入院后2周服用阿司匹林出院。在4个月的随访中，左分水岭地区的脑血流量仍然减少；然而，无复发性卒中发生.尽管颈内动脉狭窄的手术或血管内介入治疗的适应症主要取决于狭窄程度，对于颈内动脉狭窄和持续性原始三叉神经动脉的患者，建议进行脑血流评估。
