- 25 patients who were treated with RFA for pHPT in this report.
- 21/25 had normal PTH at 6 months.
- Minor complications of neck pain and one case of transient voice change.
- The used hydrodissection to set a 5 mm barrier between the PTA and vital structures. They injected 10-30 ml normal saline in order to avoid thermal injury of critical structures by forming a liquid isolation zone greater than 5 mm between the parathyroid
and adjacent structures.
- I do not use saline as it is an conductor of electricity. I use dextrose instead.
- RFA was performed using the moving-shot technique and trans-
- The RFA power was 3-7 Watts.
- If a transient hyperechoic zone did not form at
the electrode tip within 5–10 s, the radiofrequency power was gradually increased.
- Failed response occurred with a larger size adenoma and if multiple glands were involved.
- Ideal size for RF ablation is around 1 cm.
- Very small PTAs <0.6 cm are also more difficult to ablate.
- The procedure takes about 5 minutes.
