1. Introduction
Thyroid nodules are incredibly common, with up to 50% of Americans developing at least one by the age of 60. While most thyroid nodules are benign, some may cause discomfort, affect surrounding structures, or simply become a cosmetic concern. At Aidendo, we specialize in advanced treatments for thyroid conditions, including Radiofrequency Ablation (RFA), a minimally invasive procedure offering an effective alternative to traditional surgery.
2. What is radiofrequency ablation?
Radiofrequency Ablation (RFA) is a cutting-edge procedure designed to treat thyroid nodules without the need for invasive surgery. During the procedure, a probe is inserted into the thyroid nodule, and heat is applied to shrink the nodule from the inside. Over the course of several months, the nodule collapses, reducing in volume by 50-80%. Unlike surgery, RFA preserves healthy thyroid tissue, allowing the thyroid to continue functioning normally.
Compared to traditional surgery, RFA has several advantages:
- Minimally invasive: No large incisions or general anesthesia are required.
- Preserves thyroid function: The rest of the thyroid remains intact, reducing the risk of hypothyroidism.
- Short recovery time: Patients can return to normal activities the same day.
3. Safety considerations in RFA
At Aidendo, patient safety is our top priority. We take numerous precautions to ensure the procedure is performed safely and effectively. From carefully screening patients to monitoring them during and after the procedure, our goal is to minimize risks and maximize outcomes.
Dr. Vandyke has extensive training and experience in performing RFA. Having completed her endocrinology fellowship in 2018, she has been practicing in the DFW metroplex and has made thyroidology a significant part of her practice. Her expertise ensures that each procedure is performed with precision and care.
4. Patient selection and preparation
Not every patient is a candidate for RFA, and careful patient selection is crucial for successful outcomes. At Aidendo, we consider the following criteria for RFA candidates:
- Benign thyroid nodule confirmed by two biopsies.
- “Hot” or “toxic” nodules with one benign biopsy.
- Patients who want to preserve thyroid function and avoid surgery.
- Patients who can comfortably lie with their neck extended during the procedure.
Patients who are not good candidates include those who are pregnant, have pacemakers, thyroid cancers, or blood clotting disorders. During pre-procedural counseling, we work with patients to set clear expectations and ensure they are fully informed about the procedure and recovery process.
5. The RFA procedure
The Radiofrequency Ablation procedure is performed using advanced ultrasound imaging for precise targeting of the nodule. Here’s a step-by-step overview of the process:
- Preparation: The patient is positioned on the table, and grounding pads are applied to the legs. Using ultrasound, we identify the thyroid nodule and numb the area with local anesthesia.
- Procedure: A small probe is inserted into the nodule, and heat is applied to “cook” the inside of the nodule from multiple angles. The entire process takes 1-2 hours, depending on the size and location of the nodule.
- Minimally invasive: Patients remain awake during the procedure, experiencing only mild pressure. No general anesthesia is required.
6. Post-procedure care and outcomes
After the procedure, patients are monitored closely and can go home the same day. Since only local anesthesia is used, most patients are able to resume normal activities immediately. Some may experience mild swelling or bruising, which typically resolves on its own within a few days. Overall, the complication rate for RFA is low—around 1-2%.
At Aidendo, we have seen excellent outcomes with RFA, with many patients experiencing significant relief from symptoms and lasting results. The reduction in nodule size typically occurs over 3-6 months, and many patients see a 50-80% decrease in volume. For those looking to avoid surgery and preserve their thyroid function, RFA is a highly effective and safe option.
7. Conclusion
Radiofrequency Ablation (RFA) offers a safe and effective treatment option for patients with symptomatic or large thyroid nodules. With minimal downtime and excellent outcomes, RFA is a great alternative to traditional surgery. If you’re experiencing discomfort or cosmetic concerns from thyroid nodules, consider RFA as your primary treatment option.
