颈部动脉粥样硬化及斑块所致的血管狭窄是脑缺血发作的危险因素之一[1],早期发现并了解其狭窄程度和病变性质是决定治疗方案的重要参考指标。彩色多普勒超声是最常用而可靠的诊断手段。随着高频彩色多普勒超声诊断技术的不断进展,颈动脉、椎动脉颅外段病变的显示率不断提高。本
Cervical atherosclerosis and plaque-induced vascular stenosis is one of the risk factors for ischemic stroke [1]. Early detection and understanding of the degree of stenosis and the nature of the lesion are important prognostic indicators for treatment regimens. Color Doppler ultrasound is the most commonly used and reliable diagnostic tool. With the continuous development of high-frequency color Doppler ultrasound technology, carotid and vertebral arteries show an increasing rate of extracranial lesions. this
