目的探讨乳腺癌腋窝淋巴结转移的彩色多普勒超声(CDFI)特点。方法采用二维及CDFI超声对66例乳腺癌伴同侧腋窝淋巴结肿大患者的声像图进行分析,分析淋巴结的数目、形态、大小、纵/横比值、淋巴门、血流信号分布及血流参数。结果转移组淋巴结多为多发性,可融合成团,淋巴门偏心或消失,血流信号丰富、紊乱,周边型多见。结论二维及CDFI超声检查有助于良、恶性淋巴结的鉴别,是检查乳腺癌腋窝淋巴结转移最简便的方法之一。
Objective To investigate the characteristics of color Doppler ultrasonography (CDFI) in axillary lymph node metastases of breast cancer. Methods Two-dimensional and CDFI ultrasonography were used to analyze the sonograms of 66 cases of breast cancer with ipsilateral axillary lymphadenopathy. The number, shape, size, longitudinal and transverse ratios of lymph nodes, lymphatic vessels, blood flow signal distribution and blood flow were analyzed. parameter. Results The lymph nodes in the metastatic group were mostly multiple, they could fuse into groups, and the lymph nodes were eccentric or disappeared. The blood flow signals were abundant and disordered, and peripheral types were more common. Conclusion Two-dimensional and CDFI ultrasonography is helpful for the identification of benign and malignant lymph nodes. It is one of the easiest methods to detect axillary lymph node metastasis in breast cancer.
