Radiofrequency Ablation (RFA) of Benign Thyroid Nodules in Patients with Incompletely Resolved Clinical Problems after Ethanol Ablation (EA)

Background Although ethanol ablation (EA) is effective, refractory cases have been reported in 5–25% of patients, with a marked decline in efficacy on subsequent reattempt. The aim of this study was to evaluate the role of radiofrequency ablation (RFA) after EA of benign thyroid nodules in patients with incompletely resolved initial clinical problems.
