卒中是老年人致死致残的主要原因之一,给患者个人、家庭和社会带来沉重负担。约20%的缺血性卒中由大血管动脉粥样硬化引发,约7%脑血管事件与明显的颈动脉狭窄有关。越来越多的证据证明,脑血管危险分层除了与狭窄程度有关,也与颈动脉粥样硬化斑块的形态特征有关。其中斑块易损性(如表面完整性、组织性特征等)极大地增加了卒中风险。颈动脉斑块回声与同侧脑缺血性卒中风险相关。对于 Stroke is one of the major causes of death and disability of the elderly, posing a heavy burden to the individual patient, family and society. Approximately 20% of ischemic stroke is caused by macrovascular atherosclerosis and about 7% of cerebrovascular events are associated with significant carotid stenosis. More and more evidences that cerebrovascular risk stratification in addition to the degree of stenosis, but also with the carotid atherosclerotic plaque morphological characteristics. In which plaque vulnerability (such as surface integrity, histological features, etc.) greatly increased the risk of stroke. Carotid plaque echo is associated with the risk of ipsilateral ischemic stroke. for
