1. While RF is the first line alternative treatment for PTA, some patients have contraindication to RF. The presence of metal in the patient’s body can be a reason to avoid RF.
2. Use of PEI is then the next alternative to parathyroid surgery.
3.The article below uses RF to treat PTA.
4. Specific techniques have boosted the development of nonsurgical, minimally invasive procedures, such as percutaneous radiofrequency ablation (RFA) and ethanol ablation under ultrasonographic guidance, which are gaining popularity as a methods of treatment.
Percutaneous sonography-guided radiofrequency ablation in the management of parathyroid adenoma
Shuang-ying Xu et al
Case 1 the patient underwent RFA for the purpose of decreasing his serum calcium and PTH levels, as well as to reduce the signs and symptoms associated with hyperparathyroidism. Subsequently, a radiofrequency generator (Celonlab ENT system, Celon AG, Germany) with an internal needle electrode was used for ablation of the adenomatous tissue. The radiofrequency needle was inserted into the centre of the parathyroid adenomatous tissue, and an ablation power of 5 W was applied for 12 min.Although there was transient hoarseness after the procedure, the patient spontaneously improved two days post procedure. Pathologic findings confirmed the diagnosis of parathyroid adenoma. 99mTc-sestamibi scintigraphy performed after ablation revealed no abnormal uptake.
Fig. 2 shows the difference in uptake pre- and post procedure. Four days after the procedure, the patient presented with hypocalcaemia (1.84 mmol/L), which was resolved (2.68 mmol/L) within two weeks with the use of calcium replacement therapy. Two months after the procedure, the patient’s serum levels of PTH, calcium and phosphate had normalised, and there was a reduction in his gastrointestinal and bone disease symptoms.
Case 2A 54-year-old man with a ten-year history of type 2 diabetes mellitus and a two-week history of general fatigue and bone pain was admitted to our hospital. He had a markedly elevated PTH level (> 1,900 ng/L) and hypercalcaemia (3.79–4.57 mmol/L). Symptoms at presentation included osteoporosis and nephrolithiasis. Colour Doppler ultrasonography of the neck detected a large hypoechoic mass dorsal to the left inferior pole of the thyroid gland, possibly originating from the parathyroid gland. Subsequent computed tomography (CT) of the neck revealed a large oval mass, measuring 26.78 mm × 22.40 mm × 4.90 mm, in the left parathyroid gland (Fig. 3).The parathyroid adenoma was treated successfully using RFA under ultrasonographic guidance. The ablation power and time were 5 W and 30 min, respectively. The RFA procedure was well tolerated by the patient.At two months after the procedure, the patient’s serum calcium level remained normal while his serum PTH level continued to decrease, as evidenced by the reduction of symptoms experienced by the patient.
