目的:探究高频彩超在甲状腺癌颈部淋巴结转移的临床诊断中的价值,为临床准确的诊断治疗提供参考。方法:选取我院2012年1月到2016年1月就诊的可疑甲状腺癌颈部淋巴结转移的患者56例作为研究对象,对所有患者均进行高频彩超方面的检查。观察患者高频彩超的淋巴门部回声不均匀情况、边缘是否有缺损、钙化以及检测血流收缩期峰值速度(Vmax)、阻力指数(RI),另外测量患者颈部淋巴结的纵径(Dv)和横径(Dt)且以手术后的病理结果作为标准进行研究分析。结果:通过对56例疑为甲状腺癌颈部淋巴结转移的检测,高频彩超检查对甲状腺癌颈部淋巴结转移疾病的阳性诊断率为83.78%,淋巴结非转移性阴性率为76.19%,诊断的正确率为81.03%。其他Vmax、RI等指标淋巴结转移的患者明显高于淋巴结非转移的患者,另外淋巴结的转移主要分布在颈部的Ⅱ、Ⅲ和Ⅳ区域。结论:高频彩超是诊断甲状腺癌颈部淋巴结转移的简便、有效的方式之一,诊断准确性较高,对临床疾病的诊断和治疗具有有重要的指导意义,值得在临床推广。
Objective: To investigate the value of high frequency ultrasound in the diagnosis of cervical lymph node metastasis of thyroid cancer and provide a reference for clinical diagnosis. Methods: Fifty-six patients with suspected cervical lymph node metastasis from January 2012 to January 2016 in our hospital were enrolled in this study. All patients underwent high-frequency ultrasound examination. To observe the uneven echogenicity of lymphatic glands, the presence or absence of defects on the margins, the calcification, the peak velocity of systolic velocity (Vmax) and the resistance index (RI) in patients undergoing high-frequency ultrasound, and to measure the longitudinal dimension (Dv) And diameter (Dt) and the postoperative pathological results as a standard for research and analysis. Results: According to the detection of cervical lymph node metastasis in 56 cases of suspected thyroid cancer, the positive diagnosis rate of cervical lymph node metastasis of thyroid cancer by high frequency color Doppler ultrasound was 83.78% and the negative rate of non-metastatic lymph nodes was 76.19%. The diagnosis was correct The rate was 81.03%. Other Vmax, RI and other indicators of lymph node metastasis were significantly higher in patients with non-lymph node metastasis, the other lymph node metastasis mainly in the neck Ⅱ, Ⅲ and Ⅳ area. Conclusion: High-frequency ultrasound is one of the simple and effective methods to diagnose cervical lymph node metastasis of thyroid cancer. The diagnostic accuracy is high, which has important guiding significance for the diagnosis and treatment of clinical diseases, which is worthy of clinical promotion.
