Abstract


Objective:To study the ultrasonography thyroid papillary carcinoma cervical lymph node metastases diagnostic value.Methods:a retrospective analysis by 2010 year 2009 at our hospital diagnosed with thyroid papillary carcinoma patients with cervical lymph node enlargement of 154 cases of application SPSS 17.0 statistics software analysis: ultrasonology thyroid papillary carcinoma metastatic lymph nodes in the morphological characteristics, boundary and internal echographic features and nodal internal blood supply characteristics of counting chi-square test data. Results:154 patients with thyroid papillary carcinoma patients were agent and ultrasonic cervical lymph nodes 326 medal. By operation or puncture after pathological diagnosis thyroid papillary carcinoma lymph node metastasis of 126 patients, metastatic lymph nodes for 267 pieces, the lymph node metastasis 28 cases, for non-metastatic lymph node for 59 medal. Ultrasound diagnosis lymph node metastasis accuracy 81.8%, thyroid papillary carcinoma metastatic lymph node aspect ratios (length-diameter/short diameter)<2(85.0%), lymph node is the echo of the internal non-uniform (75.3%), lymph node boundary owe rules (74.2%), lymph nodes can be seen in tiny calcification (53.6%). Thyroid papillary carcinoma metastatic lymph node group and neck non-metastatic lymph node group differences between the ultrasonic index was statistically significant (P<0.05). Thyroid papillary carcinoma cervical lymph node metastases of blood flow distribution is more abundant, higher than non-metastatic lymph node group (P<0.05).Conclusion:thyroid papillary carcinoma cervical lymph node metastases of a round or class round, aspect ratios (length-diameter/short diameter)< 2, and fusion of lymph node is diagnostic thyroid papillary carcinoma or cervical lymph node metastasis, one of the important characteristics of cervical lymph node within see tiny calcification highly suggestive of thyroid papillary carcinoma cervical lymph node metastases. Ultrasound is the thyroid papillary carcinoma cervical lymph node metastases a simple and effective method, the results of the study on clinical guidelines for accurate ultrasound diagnosis and improve diagnosis level to have the important meaning.
