目的:颈动脉粥样硬化是引起缺血性脑卒中的重要原因。粥样硬化斑块形成是动脉粥样硬化的明显特征。它反映动脉粥样硬化的程度。我们采用彩色超声对100例经CT确诊为脑梗塞患者进行颈动脉粥样硬化斑块与脑梗塞发生关系的探讨。对颈动脉粥样硬化斑块好发部位,斑块大小、形态、性质,回声强度进行观测。测量颈部动脉内膜中层厚度(IMT),管腔宽度,是否狭窄及其程度,运用彩色多普勒观察整个管腔的血流动力学情况。 Objective: Carotid atherosclerosis is an important cause of ischemic stroke. Atherosclerotic plaque formation is a prominent feature of atherosclerosis. It reflects the degree of atherosclerosis. We used color ultrasound in 100 cases of CT-diagnosed cerebral infarction in patients with carotid atherosclerosis plaque and cerebral infarction relationship. Carotid atherosclerotic plaque spot, plaque size, shape, nature, echo intensity were observed. The carotid intima-media thickness (IMT), lumen width, stenosis and the extent of stenosis were measured. The hemodynamics of the entire lumen were observed by color Doppler.
