目的:探讨彩色多普勒超声在颈动脉体瘤诊断及鉴别诊断中的临床应用价值。材料与方法:回顾性分析了10例经确诊的颈动脉体瘤的彩色多普勒超声特征。结果:颈动脉体瘤肿块位于颈总动脉分叉处,颈内及颈外动脉间距增宽,瘤体常呈实质低回声,边界清晰,较大瘤体常围绕血管生长;彩色多普勒超声显示肿瘤内丰富彩色血流信号,动脉血流为主,能显示瘤体与颈动脉的关系。结论:彩色多普勒超声不仅能对颈动脉体瘤作出明确诊断,而且能显示瘤体与颈动脉的关系。
Objective: To investigate the clinical value of color Doppler ultrasound in the diagnosis and differential diagnosis of carotid body tumor. Materials and Methods: The color Doppler ultrasound features of 10 confirmed carotid body tumors were retrospectively analyzed. Results: The carotid body tumor was located at the bifurcation of the common carotid artery. The distance between the internal carotid artery and the external carotid artery was broadened. The tumor was usually hypoechoic with clear boundary and the larger tumor often grew around the blood vessel. Color Doppler ultrasound The tumor showed abundant color flow signals, arterial blood flow, can show the relationship between the tumor and the carotid artery. Conclusion: Color Doppler ultrasound can not only make a clear diagnosis of carotid body tumor, but also show the relationship between tumor and carotid artery.
