[Ultrasound guided percutaneous microwave ablation in the treatment of recurrent thyroid nodules]
Objective:
To explore the clinical effect of ultrasound guided microwave ablation in the treatment 01 recurrent thyroid nodules.
Method:
Seventy-five cases of recurrent thyroid nodules were treated with ultrasound guided microwave ablation(MWA) under local anesthesia. All the patients underwent biopsy puncture, then the microwave ablation needle puncted in the center site of nodule with energy of 25-35 W, and the center tempera- ture could reach to 70-95 °C.
Result:
MWA were successfully performed in all the patients without significant com- plications. Temporary hoarseness occurred in 5 cases and dispeared after 1-3 weeks, choking water occurred in 2 patients and recovered 3-5 days later. Ultrasound examination showed that the bloodstream of thyroid nodules disappeared in all the patients, and the nodules diminuted with varying degrees at 3-month and at 6-month follow- up Serum FT4 and TSH did not change significantly.
Conclusion:
Ultrasound guided MWA could be effective in the treatment of recurrent thyroid nodule with minimal invasive technology.
