[Radiofrequency ablation of benign thyroid nodules].

The aim of this article was to report our first results of radiofrequency ablation (RFA) of benign thyroid nodules. The first radiofrequency ablation was performed in Sweden on 15 March 2024. Until February 2025 15 RFA treatments were completed. Inclusion criteria were the following: ≥18 years of age, compression symptoms, nodule >2.0 cm, solid component >30%, and benign cytology (Bethesda II) in two separate cytological assessments. RFA was performed using the »moving shot« technique and transisthmic approach. Nodule volume and symptoms were evaluated before treatment and during follow-up at 3 months, 6 months, and 12 months. The volume reduction rate was 40-71% (mean 63%) at 3-month control, 54%-85% (mean 71%) at 6-month control and 57-94% (mean 77%) 12-month control. There was no major complication. Minor complications (pain during intervention) were observed. RFA is an effective non-surgical treatment for patients with benign thyroid nodules.
