Abstract
Percutaneous ultrasound-guided Radiofrequencyablation (RFA) is a minimally invasive treatment that has been widely used as an alternative to surgery in the care of patients with malignant tumors of the liver, renal cell carcinoma, and other tumors. Recently, RFA is an alternative treatment modality for benign thyroid nodules instead of surgery, mainly for the cosmetic reasons, and limited cases of local recurrences or focal distant metastases of differentiated thyroid cancer in the high-risk reoperative condition or for the palliative purpose. However, RFA for the initial treatment of the DTC is rare. We report a case of RFA for the papillary thyroid microcarcinomain the high-risk surgical patient. A 49-years-old woman with congestive heart failure due to severe mitral valve regurgitation, chronic kidney disease, and type 2 diabetes was incidentally diagnosed with papillary microcarcinoma without metastasis. She underwent RFA. During 5-year follow-up, there is no recurrence of the findings.
Highlights
Radiofrequency (RF) ablation is an alternative treatment modality for benign thyroid nodules instead of surgery [1,2,3]
Ito et al reported they just observed in papillary thyroid microcarcinoma (PTMC) patients who did not show unfavorable features without surgery and suggested PTMCs that are not associated with unfavorable features can be a candidates for observation without surgery [8]
The procedurerelated complications is neck discomfort, skin burn, and changes in voice. Serious complications, such as injury to the esophagus, trachea, or other nerves have not been reported following the treatment of recurrent thyroid cancers, which can be located near these structures [4,5,6,11,12]
Summary
Radiofrequency (RF) ablation is an alternative treatment modality for benign thyroid nodules instead of surgery [1,2,3]. Most of patients with PTC can be effectively treated with thyroidectomy, surgery is impossible in patients who refuse surgery or have too high risk to undergo a surgical procedure. We present a case of PTMC patient who was treated by a non-surgical ultrasound (US)-guided RF ablation due to being under high surgical risk.
