PTA No Surgery 101: Radiofrequency Ablation RFA for Parathyroid Adenoma PTA.
Inferior parathyroid adenoma is the most common location and is the best for RF ablation using Dextrose microdissection before the ablation.
- A simple injection of dextrose not saline as mentioned in this article inferomedial to the parathyroid, is a safe technique that prevents burn injury to the nerve.
- This is called microdissection and is done prior to the ablation and moves the parathyroid laterally away from the recurrent nerve.
- The amount of heat needed to ablate a PTA is very low. Example is 200 watts for liver,20-50 watts for a thyroid nodule and 5-10 watts for a PTA.
- This is the future and will decrease the number surgery for PTAs.
- Call me for details as I do this is my office ultrasound room not in the hospital.
- My charges are less than RF done in the hospital by radiologists.

Radiofrequency ablation of parathyroid adenoma in primary hyperparathyroidism
We present a case of a 32-year-old woman with hyperparathyroidism, treated with ultrasound-guided percutaneous radiofrequency ablation (RFA). RFA, assisted by saline injection inferomedial to the parathyroid, is a safe technique that prevents burn injury to the nerve. The saline injection technique shifted the parathyroid gland laterally, so that the distance between the nerve and the parathyroid gland was sufficient to prevent burn injury. The completeness of tissue ablation was evaluated based on Doppler ultrasound imaging and serum intact parathyroid hormone (iPTH) level immediately after RFA. There were no complications associated with RFA. Serum iPTH levels normalized during follow-up for 20 months. It was possible to perform RFA for primary parathyroid adenoma safely using a saline injection technique.
