Here, we describe a case of a 67-year-old man who was transferred to our hospital with complaints of sudden upper right limb weakness and ataxia. Scattered acute cerebral infarction was found in the watershed zone between the left anterior cerebral artery and the middle cerebral artery territories. A shelf-like structure at the origin of the left carotid artery and a vulnerable plaque distal to the lesion was found. Symptomatic atherosclerotic plaque with concomitant carotid web was diagnosed. Carotid endarterectomy resulted in good revascularization. Hemodynamic changes associated with vascular stenosis are involved in atherosclerosis. The current case is valuable and shows that carotid web can cause not only embolic infarction but also cerebral thrombosis due to atheroma formation in the carotid artery.
这里，我们描述了一例 67 岁男性患者，他因突发右上肢体无力和共济失调转入我院。在左侧大脑前动脉和大脑中动脉区域之间的分水岭区发现散在的急性脑梗死。在左侧颈总动脉的起源处发现了一个架子状结构和病变远端的易损斑块。诊断为伴有颈动脉网的症状性动脉粥样硬化斑块。颈动脉内膜切除术实现了良好的再血管化。与血管狭窄相关的血流动力学变化与动脉粥样硬化有关。本例很有价值，表明颈动脉网不仅可以引起栓塞性梗死，还可以由于颈动脉粥样硬化形成导致血栓形成。
