RFA Radiofrequency Thyroid Ablation 101: The Thyroid RF Mini Electrode and The Technique
The short length 7 cm and 18 gauge modified straight internally cooled electrode is ideal for thyroid nodule ablation. 3,5,7, and 10 mm active tips allow use on smaller targets such as cancer lymph nodes.
The method is inserting the electrode medial the isthmus to
the lateral target nodule. A transverse ultrasound view is used during the RF ablation.
Why this approach?
- Entire length of the electrode is visible on transverse US imaging.
- Minimal exposure to recurrent nerve and esophagus in the danger triangle shown by the yellow dot.
- The electrode passes through sufficient amount of thyroid tissue which prevents a change of position of the electrode tip during swallowing or talking as well as preventing leakage of hot ablated fluid.
- This technique is taught during my introduction to RFA in my Master’s class which includes ethanol ablation. Call Matt at 31-393-8860 if you are an endocrinologists doing your own USGFNA, or if you are a patient interested in RFA evaluation to travel to Italy or Korea now for treatment instead of surgery.
