To reduce parathyroid hormone concentrations in uraemic patients refractory or hyporesponsive to calcium supplements and active metabolites of vitamin D, we developed in 1982 a new parathyroid ablative technique consisting of percutaneous fineneedle ethanol injection (PFNEI) into enlarged parathyroid glands under ultrasonic guidance. Fifty uraemic patients have been treated. Decreases in carboxy terminal parathyroid hormone (PTH) were 50% or more in 13 of 50 patients followed up (26%) at 1 month, in 13 of 48 (27%) at 6 months, and in 9 of 25 (36%) at 12 months. Decreases of 30% or more in PTH were obtained in 21 of 50 (42%), in 25 of 48 (52%), and in 15 of 25 (60%). In responsive patients, serum total alkaline phosphatase was significantly reduced [from 579 ± 645 U/l to 360 ±354 U/l (P < 0.01) at 6 months, and to 273 ± 311 U/l (P < 0.01) at 12 months] and bone isoenzyme decreased similarly [from 482 ±608 U/l to 256 ±344 U/l (P< 0.005), and to 225±354 U/l (P<0.01)]. The best results were in seven patients who had relapsed after subtotal parathyroidectomy. Declines in PTH of 30% or more were observed in four of seven patients at 1 month, in six of the seven (85%) at 6 months, and in all four patients seen after 12 months. The treatment corrected hypercalcaemia, making it possible to start or to increase daily vitamin D treatment. Side-effects were mild, rare, and transient.
