彩色多普勒超声诊断乳头状甲状腺癌术后复发的临床价值

Clinical Value of Color Doppler Ultrasound in the Diagnosis of Postoperative Recurrence of Papillary Thyroid Carcinoma

目的总结分析彩色多普勒超声诊断乳头状甲状腺癌术后复发的临床价值。方法选择2012年6月~2014年11月期间我院收治的40例经手术和病理检查确诊为乳头状甲状腺癌术后复发患者为研究对象,分析其术后复发时间、复发位置以及复发肿瘤的彩色多普勒超声图像特点。结果彩色超声诊断复发肿瘤病灶准确率为92.50%;术后复发时间（2.1±0.5）年。35例颈部淋巴结转移、2例患侧甲状腺床复发、2例对侧甲状腺复发、1例肺及纵膈转移。复发病灶直径平均（1.2±0.6）cm;外形为类圆形或呈不规则形状。血流特征显示情况为：28个为混合型、15个为周围型、12个无血流。结论乳头状甲状腺癌术后6个月~3年是复发高峰期,多为颈部淋巴结转移,彩色多普勒超声可对复发肿瘤进行定性和定位,是乳头状甲状腺癌术后复发的首选诊断手段。

Objective To summarize the clinical value of color Doppler ultrasound in the diagnosis of postoperative recurrence of papillary thyroid carcinoma.Methods 40 patients with papillary thyroid carcinoma who were treated in our hospital from June 2012 to November 2014 were studied.The patients were diagnosed as papillary thyroid carcinoma.The characteristics of color Doppler ultrasound were analyzed.Results The accuracy rate of color ultrasound in the diagnosis of recurrent tumor was 92.50%,and the time of recurrence was（2.1±0.5） year.35 cases of cervical lymph node metastasis,2 cases of recurrent thyroid bed,2 cases of contralateral Thyroid Recurrence,1 cases of pulmonary and mediastinal metastasis.The average diameter of the lesions was（1.2±0.6） cm,the shape was round or irregular.Blood flow characteristics were as follows：28 were mixed type,15 were peripheral type,12 had no blood flow.Conclusion 6 months after the operation of papillary thyroid carcinoma,3 years is the peak of recurrence,and more for the cervical lymph node metastasis,color Doppler ultrasound can be used for the diagnosis of recurrent tumor,is the first choice for the diagnosis of recurrent papillary thyroid cancer.
