目的 :探讨高频超声检查在乳腺癌术前检测腋下淋巴结的临床价值。方法 :对 5 2例乳腺癌患者术前行腋下部位高频超声检查 ,观察有无肿大淋巴结 ,淋巴结形态、大小、数目等二维声像图特征及彩色血流改变 ,术后与病理对照分析。结果 :5 2例腋下高频超声检查中 ,34例检出淋巴结 ,敏感性 6 5 %。病理证实淋巴结有转移的 11/ 34例 ,淋巴结无转移 2 3/ 34例。结论 :高频超声是检出乳腺癌腋窝淋巴结转移一种简便有效的方法 ,淋巴结短径 >5 mm,长 /短径比 <2 ,可作为诊断腋下淋巴结转移的参考指标 ,边缘形态 ,内部回声 ,彩色多普勒血流等可作为诊断淋巴结转移的参考声像图征象
Objective: To investigate the clinical value of high-frequency ultrasonography in the detection of underarm lymph nodes before breast cancer. Methods: 52 cases of breast cancer patients underwent high-frequency ultrasonography before surgery to observe the presence of enlarged lymph nodes, lymph node morphology, size, number and other two-dimensional sonographic features and color flow changes, postoperative and pathological Control analysis. Results: In 52 cases of axillary high frequency ultrasound examination, 34 cases detected lymph nodes, the sensitivity of 65%. Pathological confirmed lymph node metastasis in 11/34 cases, no lymph node metastasis 23/34 cases. Conclusion: High-frequency ultrasonography is a simple and effective method to detect axillary lymph node metastasis in breast cancer. The short diameter of lymph node> 5 mm and the ratio of length / short diameter <2 can be used as a reference index for diagnosis of axillary lymph node metastasis. Echo, color Doppler blood flow can be used as a diagnostic sonographic lymph node metastasis of the reference echocardiographic signs
