二维及彩色多普勒超声在颈动脉体瘤诊断中的应用

目的 探讨二维及彩色多普勒超声在颈动脉体瘤诊断中的应用价值。方法 回顾性分析了12例颈动脉体瘤患者的二维及彩色多普勒超声表现。所有病例均经手术病理证实。结果 颈动脉体瘤二维超声表现为颈动脉分叉处见实质性低回声肿块，边界清晰，边缘规则或呈分叶状。肿瘤较小时，多位于颈总动脉分叉处，使颈内、外动脉间距增大，形状多较规则；肿瘤较大时，常围绕血管生长。彩色多普勒超声表现为所有肿瘤内均可见较丰富的彩色血流信号，以动脉血流为主，能清晰地显示肿瘤与颈动脉的关系。结论 二维及彩色多普勒超声对诊断颈动脉体瘤具有无创、安全、特异性强等特点，有利于同颈部其他性质包块的鉴别诊断，是诊断颈动脉体瘤的首选方法。

Application of two-dimensional and color Doppler flow imaging in diagnosis of carotid body tumors

Objective To explore the value of two dimensional and color Doppler flow imaging(2D CDFI)for the diagnosis and differentiation of the carotid body tumor.Methods Retrospective analysis was made on 12 patients with carotid body tumor examined by 2D CDFI,and differentiations were conducted between several similar diseases.All the cases were confirmed by surgical pathology.Results The carotid body tumor in 2D CDFI was shown as follows: Low echoic substantial masses were found in the carotid branch with clearly boundary,and or partly outline.Most in small size were located at the branch of common carotid artery,so the interval between external and internal carotid arteries was enlarged.The masses in big size always grew around common cartid artery internal carotid artery and external carotid artery.More color flow signals were detected in the masses,and most were artery flow.The relationship between the mass and the carotid was shown clearly by 2D CDFI.Conclusions 2D CDFI is a valuable and practical method in diagnosis of carotid body tumors.
