Under Ultrasound Guidance,through The Way Of Percutaneous Radiofrequency Ablation To Treat Cervical Lymph Node Metastasis Which Caused After The Operation For The Thyroid Cancer

Purpose: To investigate the efficacy of treatment for Cervical lymph nodemetastasis which caused after the operation for the thyroid cancer through the way ofpercutaneous radiofrequency ablation.Methods: By using Fine needle aspiration cytology pathology,seventhyroid cancer patients be confirmed18Cervical lymph node metastasis,under ultrasound guidance，through the way of percutaneous radiofrequency ablationto treat Cervical lymph node metastasis.Results:18Cervical lymph node metastasis were once ablated, successfully, nowthe patients are survival. With a mean follow-up10.5months, through the ultrasoundreview we found that seven Cervical lymph node metastasis disappeared, absorbed morethan80%in five,50%-80%in four, less than50%in two. We found no recurrence ofCervical lymph node metastasis.Conclusion: under ultrasound guidance， through the way of percutaneousradiofrequency ablation to treat Cervical lymph node metastasis is a new method fortreating the recurrent thyroid cancer. Radiofrequency ablation is feasible and safe,littletrauma,high repetitiveness and have broad applications.
