Radio Frequency Ablation

Radiofrequency ablation (RFA) is a minimally invasive medical procedure that uses heat generated by high-frequency electrical currents to treat certain conditions, including thyroid nodules that cause discomfort, compression of nearby structures, or produce excessive thyroid hormone. It is generally recommended when nodules are symptomatic, causing swallowing or breathing difficulties, or when traditional treatment approaches (such as medication) have not been effective.

Numerous studies have demonstrated the effectiveness and safety of radiofrequency ablation for shrinking thyroid nodules. Research has shown that RFA can significantly reduce the size of nodules, alleviate symptoms, and improve patients' quality of life. However, like any medical procedure, individual results may vary.

RFA has been found to:

• Be minimally invasive, as it is performed through the skin, avoiding the need for open surgery and related risks,
• Have a short recovery time as patients usually resume normal activities within a few days,
• Reduce symptoms, alleviating discomfort, improve breathing, and swallowing,
• Have a high success rate with nodule size reduction and symptom improvement commonly achieved.
• Compared to surgical thyroidectomy (removal of the thyroid gland), RFA is a non-surgical, and less invasive option, performed through the skin without the need for large incisions, and minimal scarring.

Risks include:

• Pain at the treatment site which is usually temporary,
• Voice changes in rare cases, as RFA may affect the vocal cords,
• Nodule regrowth,
• Skin burns in rare cases.

Should your VM Med Thyroid Specialist or your referring doctor recommend RFA, you can expect the following:

Before your RFA – Your doctor will

• Review your medical history and perform necessary tests to determine if RFA is suitable for you. This includes thyroid function test, thyroid ultrasound, thyroid biopsies proving the nodule is benign (according to the guidelines, for most nodules: 2 regular FNA or one AFIRMA is needed).
• Provide pre-procedure instructions, such as you might be advised to avoid certain medications, fasting, or other preparations before the procedure.

During your RFA – Your doctor will

• Administer local anesthesia to the treatment area to minimize discomfort.
• Insert a needle insertion into the nodule using ultrasound imaging.
• Use the needle to emit Radiofrequency energy (controlled heat) to destroy the nodule's tissue.
• Monitor the procedure in real-time using ultrasound.

After your RFA

• You may experience some discomfort or pain, which could be managed with pain medication as directed by your doctor
• Most patients can resume normal activities within a few days, and regular follow-up appointments and imaging may be recommended to monitor your progress and ensure the nodule's response to treatment.

You can expect your VM Med Thyroid Specialist to discuss your specific case and any concerns you may have with you prior to deciding on a specific course of action. Our team will provide personalized guidance and help you make an informed decision about whether RFA is the right option for you.
