Objective:To investigate the safety and efficacy of ultrasound-guided percutaneouslymicrowave ablation(MWA)on benign nonfunctioning thyroid nodules.
Methods: A total of 41patients with 41 benign thyroid nodules were treated by MWA in Jiangsu Province Academy of Traditional Chinese Medicinefrom January 2016to December2017. The changes of thyroid nodule volume, effective rate, thyroid function and the incidence of complications were observed respectively before treatment as well as at the postoperative 1, 6,12 months follow-up, respectively.
Results:The medianvolume decreased from5.88mlto0.65ml. The mean volume reductionrate after 12 months was82.76±12.68%,and the effective rate was eventually 100%. No serious complications were observed. Thyroid function and autoimmune antibodylevelswerenot affected by MWA, however, serum thyroglobulinlevel was decreased after MWA. Compared with baseline, the level of ACR TI-RADS of thyroid nodules increased from TR3 to TR4 at 6 months follow-up significantly (P < 0.001).
Conclusion:MWA has a good safety and efficacy in treating benign nonfunctioning thyroid nodules.
