What is Radiofrequency Thyroid Ablation RFA?

  1. RFA is a minimally invasive alternative to thyroid surgery.
  2. It can destroy large symptomatic or cosmetic nodules with heat.
  3. Heat at 60-100 C for 4-6 minutes causes irreversible damage to thyroid cells.
  4. Advantages include less cost,reduced pain and suffering, outpatient procedure,and treating poor surgical candidates.
  5. Ultrasound guided probe with cooling system is used. Special short probe with smaller gauge probe is ideal for thyroid work. Star Med Korea #18 cool tip.

  7. Roberto Valcavi,Interventional thyroidologist in Italy is seen here at the head of the patient ablating a large thyroid nodule. DR Valcavi is a pioneer in ablation methods including laser and ethanol.

  10. The probe is moved within the nodule to destroy 10 mm sections at a time. This is called moving shoot method.

  12. The left shows post RFA residul nodule, and a contrast US on right shows the ablated area in central black.
  13. The patient is off to lunch right after, and returns in 24 hours for the contrast study on the right.
  14. They are free to leave the country 24 hours after the RFA.
  15. My patients from the USA are followed by me at 2,6,12,24 months.
  16. I have had one RFA failure on a patient with a 100+ml nodule that crossed the midline making the ablation very difficult and I referred  that patient for thyroidectomy.

  18. Image shows massive goiter nodule crossing the midline where the probe needs to be inserted.
  19. The best nodules for RFA are spongiform types whereas compact nodule are more likely to have a decreased volume reduction.

  22. The effect of RFA lasts for years with usual continued decrease volume up to 4 years.

  26. This type usually has less volume reduction but still result in symptom relief and less cosmetic effect.

  30. We have come a long way from this 14 th century surgery, but we still have too many low volume surgeons causing more complications that would be avoided by a high volume surgeon. RFA is a great way to avoid any major complications of surgery.
