Complications Following Radiofrequency Ablation of Benign Thyroid Nodules: A Systematic Review

Objective: This systematic review examined whether radiofrequency ablation (RFA) is a safe treatment modality for benign thyroid nodules (BTNs). Data Sources: PubMed, Embase, and the Cochrane Library database were searched for articles that (a) targeted human beings and (b) had a study population with BTNs that were confirmed by fine?needle aspiration cytology and/or core needle biopsy. Study Selection: Thirty?two studies relating to 3409 patients were included in this systematic review. Results: Based on literatures, no deaths were associated with the procedure, serious complications were rare, and RFA appears to be a safe and well?tolerated treatment modality. However, a broad spectrum of complications offers insights into some undesirable complications, such as track needle seeding and Horner syndrome. Conclusions: RFA appears to be a safe and well?tolerated treatment modality for BTNs. More research is needed to characterize the complications of RFA for thyroid nodules.
