Selective percutaneous ethanol injection therapy (PEIT) of the parathyroid glands has been shown to be effective in chronic dialysis patients with severe secondary hyperparathyroidism. In this study, we examined whether it was possible to maintain parathyroid function within target range (intact parathyroid hormone [iPTH], 160 to 360 pg/mL) in the long term after successful destruction of hyperplastic tissue. PEIT was performed in 46 patients resistant to calcitriol pulse therapy, and all glands larger than 5 mm in diameter were destroyed by ethanol, guided by power Doppler flow mapping. Serum iPTH levels decreased from 633.3 +/- 359.9 to 226.3 +/- 204.7 pg/mL at 3 weeks and were maintained at 289.9 +/- 222.4 pg/mL at 1 year after PEIT. Total alkaline phosphatase activity decreased from 384.9 +/- 160.1 to 234.0 +/- 110.5 IU/L at 1 year after PEIT. In 19 patients, iPTH levels decreased into relative hypoparathyroidism (iPTH < 160 pg/mL) at 3 weeks after PEIT; however, they recovered at 1 year after PEIT (191.1 +/- 29.6 pg/mL). Parathyroid function was maintained within target range in 80.4% of the patients at 1 year after PEIT with appropriate medical therapy. Surgical parathyroidectomy was not required in any patient. Conversely, in eight other patients with recurrent hyperparathyroidism after subtotal parathyroidectomy, iPTH levels recovered in only 50% of the patients at 1 year after PEIT. Thus, destruction of hyperplastic tissue should be optimized in such patients. Recurrent nerve palsy was observed in only one patient, but was reversible. In conclusion, selective PEIT guided by color Doppler flow mapping is an effective and safe adjunct to medical therapy with a low risk for hypoparathyroidism.
