摘要
目的:研究高频彩色多普勒超声对乳腺癌腋窝良性淋巴结与腋窝转移性淋巴结的鉴别价值。方法:选择2015年2月~2016年6月在我院进行诊治的乳腺癌患者150例,应用高频二维超声结合彩色多普勒血流显像技术,观察腋窝肿大淋巴结的声像图及血流情况。结果:经二维超声发现,乳腺癌腋窝良性淋巴结的皮质多向心增厚(68.93%)、长短径比L/S多>2.0(70.58%)、多不融合(93.14%)、多无钙化斑(97.06%);腋窝转移性淋巴结的皮质多偏心增厚(68.48%)、长短径比L/S多<2.0(69.57%)、多融合(68.48%)、多有钙化斑(77.17%);两者相比有明显差异(P<0.05);经彩色多普勒血流显像技术发现,乳腺癌腋窝良性淋巴结的血流信号分布多呈门型(63.17%),血流丰富程度多为Ⅱ级(54.35%);腋窝转移性淋巴结的血流信号分布多呈周边型(68.93%),血流丰富程度多为Ⅲ级(72.83%);两者相比有明显差异(P<0.05)。结论:乳腺癌腋窝良性淋巴结与腋窝转移性淋巴结在内部回声、形态、血流分布特点等方面有显著的差异,高频彩色多普勒超声对乳腺癌腋窝良性淋巴结与腋窝转移性淋巴结具有较高的鉴别价值。
Objective：To study the clinical value of high-frequency color Doppler ultrasonography in identifying axillary benignant lymph nodes and metastatic lymph nodes of breast cancer.Methods：150 cases of patients with breast cancer who were treated in our hospital from February 2015 to June 2015were selected.The sonograms and characteristics of blood flow were analyzed by high-frequency two-dimensional ultrasonography combined with color Doppler flow imaging.Results：The two-dimensional ultrasound found that the cortex of axillary benignant lymph nodes mostly were centripetal thickening （68.93 %）,L/s 〉2.0 （70.58 %）,fusion （93.14 %）,multiple calcified plaque （97.06 %）;the cortex of metastatic lymph nodes mostly were eccentric thickening （68.48 %）,L/s〈2.0 （69.57 %）,fusion （68.48 %）,calcification （77.17 %）;they had significant difference （P〈0.05）;by color Doppler flow imaging found that blood flow signals distribution of axillary benignant lymph nodes mostly were door type （63.17 %）,abundant blood flow levels mostly were grade Ⅱ （54.35 %）;the blood flow signals distribution of metastatic lymph nodes mostly were peripheral （68.93 %）,the abundant blood flow levels mostly were grade Ⅲ （72.83 %）;they had significant difference （P〈0.05）.Conclusions：Axillary benignant and metastatic lymph nodes have significant different intemal echo,morphology and blood flow distribution characteristics,and the high-frequency color Doppler ultrasonography has high diagnostic value for axillary benignant and metastatic lymph nodes.
