The Two-Year Results of Using Radiofrequency Ablation as a Novel Treatment for Persistent or Relapsed Graves’ Disease: A Prospective Study

Graves' disease (GD) is the most common cause of hyperthyroidism. Antithyroid drugs (ATDs) are the first-line treatment, but when discontinued, >50% of patients experience relapses. Conventional definitive treatment options include surgery and radioiodine therapy (RAI), each with its own disadvantages. Radiofrequency ablation (RFA) achieved promising short-term remission rates in a previous pilot study. The current study reports our experience of using RFA to treat relapsed GD in the largest cohort of patients with a longer follow-up period.
