烟雾病是脑底大动脉的闭塞性血管病变。在美国,该病多见于30～40岁的女性,常引发缺血性卒中。其自然病史目前尚未明确,但根据对颈动脉粥样硬化性闭塞疾病的研究,有专家认为,血流动力学因素在烟雾病卒中的发生中起着显著作用,并预测,闭塞血管以远的大脑半球的氧摄取增加,意味着烟雾病患者在接受药物治疗的同时,仍有发生同侧卒中的风险。 Moyamoya disease is an occlusive vascular disease of the cerebral artery. In the United States, the disease is more common in women aged 30 to 40, often leading to ischemic stroke. The natural history is not yet clear, but according to the carotid atherosclerotic occlusive disease research, some experts believe that the hemodynamic factors play a significant role in the occurrence of smog stroke and predict the occlusion of blood vessels far Increased oxygen intake in the hemispheres of the brain means that patients with moyamoya disease are still at risk of developing the same side of the stroke while receiving medication.
