目的 :探讨彩色多普勒血流显像技术在颈总动脉粥样硬化与颈总动脉炎鉴别诊断中的价值。方法 :应用彩色多普勒声像图对 4 0例颈总动脉粥样硬化及 36例颈总动脉炎患者的二维声像图、彩色血流分布特征及频谱多普勒血流动力学参数进行比较。结果 :颈动脉粥样硬化患者血管内膜呈“小丘样”隆起 ,并伴有彩色血流束的充盈缺损。而颈动脉炎患者病变颈动脉血管以血管壁增厚为主 ,彩色血流束可有管状、喇叭口样狭窄。多普勒血流频谱显示颈动脉硬化患者的Vmax、RI、ACC及TA均显著低于颈动脉炎患者。结论 :彩色多普勒声像图可以作为鉴别两种颈动脉闭塞性病变的有效诊断方法。
Objective: To investigate the value of color Doppler flow imaging in the differential diagnosis of common carotid atherosclerosis and common carotid artery. Methods: The color Doppler echocardiography was performed on 40 patients with common carotid atherosclerosis and 36 patients with common carotid artery arteriosteitis. Color Doppler flow characteristics and spectral Doppler hemodynamic parameters Compare. Results: The intima of the carotid atherosclerosis showed “hill-like” bulging, accompanied with the filling defect of the color blood flow. Carotid arteritis in patients with lesions of the carotid artery thickening of the main vascular wall, color blood flow may have tubular, bell mouth-like stenosis. Doppler flow spectrum showed that Vmax, RI, ACC and TA in carotid atherosclerosis were significantly lower than those in carotid artery. Conclusion: Color Doppler echocardiography can be used as an effective method to diagnose two carotid occlusive diseases.
