Abstract：
Congenital absence of an internal carotid artery (ICA) is a rare vascular anomaly and occurs in less than 0.01% of the population. We report a case of aplastic internal carotid artery in a 34-year-old female. The patient presented to the emergency department with complaints of new-onset involuntary swaying-like movement of her right arm. Brain magnetic resonance imaging showed multifocal tiny areas of acute infarcts in the bilateral frontal, parietal, and left occipital lobes in the watershed distribution. There was no visualization of the flow of the intracranial left internal carotid artery. Follow-up CTA of the head and neck showed a congenital absence of the left internal carotid artery with no evidence of arterial dissection, occlusion, or aneurysm. Obstruction of the internal carotid artery has significant consequences for patients. This effect is amplified if the disruption occurs in the sole anterior blood supply to the parenchyma of the brain, as in this case. In our patient care, imaging was vital to the detection and subsequent treatment with anticoagulation to avoid further cerebral complications, and the patient will now have a better understanding of the increased lifetime risk of further events.
摘要：
先天性颈内动脉（ICA）缺失是一种罕见的血管异常，发生在不到0.01％的人群中。我们报告了一例34岁女性的颈内动脉再生障碍性疾病。患者向急诊科就诊，抱怨她的右臂出现了新的非自愿摇摆式运动。脑磁共振成像显示双侧额叶急性梗死的多灶性微小区域，顶叶,左枕叶在分水岭分布。没有显示颅内左颈内动脉的流量。头颈部CTA随访显示左侧颈内动脉先天性缺如，无动脉夹层，遮挡,或者动脉瘤.颈内动脉阻塞对患者具有显著的后果。如果中断发生在大脑实质的唯一前部血液供应中，这种作用会放大，在这种情况下。在我们的病人护理中，影像学检查对于检测和随后的抗凝治疗至关重要，以避免进一步的脑部并发症，患者现在将对进一步事件的终生风险增加有更好的了解。
