Atheromatous plaques are dynamic structures undergoing continuous remodeling. Duplex ultrasound is now an accepted technique to classify the severity of arterial stenoses. It gives information about the ultrasonic echogenicity of tissue, the plaque surface and the velocity of blood flowing through vessels with the latest equipment. We report the case of a 59-year-old male patient with left hemispheric stroke and a 50% left carotid artery stenosis whose remodeling and reabsorption developed throughout three months from the onset of symptoms. Plaque surface and structural echomorphology assessment and standardization, along with the degree of carotid stenosis, might be helpful in identifying patients most likely to benefit from carotid endarterectomy.
动脉粥样硬化斑块是不断进行重塑的动态结构。双功超声现已成为一种公认的用于对动脉狭窄严重程度进行分类的技术。借助最新设备，它能提供有关组织的超声回声性、斑块表面以及流经血管的血流速度的信息。我们报告了一例59岁男性患者，该患者患有左半球卒中且左颈动脉狭窄50%，从症状发作起的三个月内其斑块发生了重塑和再吸收。斑块表面和结构回声形态学评估及标准化，连同颈动脉狭窄程度，可能有助于识别最有可能从颈动脉内膜切除术中获益的患者。
