Efficacy and Safety of Radiofrequency Ablation for Benign Thyroid Nodules: A Prospective Multicenter Study.
How is the Thyroid RFA procedure done?
- Outpatient procedure.
- Under ultrasound guidance.
- RF cool tip systems used.
- 18 gauge electrode.
- Active tips vary by the size of the nodule. 7 mm for < 3 cm nodule,10 mm for <4 cm, 15 mm for >4 cm.
- Moving shot method used through the isthmus area of entry.
- Local injection of the thyroid capsule with 1-2 % Lidocaine.
- Ablation follows a system of moving the electrode through different parts of the nodule in a pre-maped out plan.
- Ablation power was 15-80 W. ( low compared to other uses of RF such as liver).
- If the patient can not tolerate the pain the power is turn lower or off and the capsule injected again with Lidocaine.
- The procedure is terminated when the nodule is ablated.
Comments: Present state is Thyroid RF is not FDA approved in the USA, and patients need to travel to Italy or Korea. This is arranged by referral after my evaluation. The patient will only have to stay 2 days just for the treatment.
