Ten years' experience in subtotal parathyroidectomy of hemodialysis patients.

Abstract：

:Secondary hyperparathyroidism (SHP) is a frequent complication of long-term dialysis patients, and surgical parathyroidectomy remains necessary in patients resistant to medical therapy. The present paper reports single center results in subtotal parathyroidectomy, presenting diagnostic procedure, indications for parathyroidectomy, and postoperative course of metabolic and endocrine disorders. Forty-seven patients (25 males and 22 females), aged 25-60 years, regularly hemodialyzed between 3-23 years, have undergone parathyroidectomy at our Clinical Center during the last 10 years. The patients had plasma iPTH levels 8-45 times higher than the top normal limit, high values of alkaline phosphatase, calcemia on the upper normal level, and hyperphosphatemia. Radiographic changes characteristic for SHP were seen in all patients before parathyroidectomy, and the most common were subperiosteal resorptions (100%), bone cysts and periosteal neostosis (66%), and extraskeletal calcifications (98%). Enlarged parathyroid glands were seen by ultrasound in 62% of patients. All patients manifested pruritus and bone pain, 89% of them had myopathy, while other symptoms and signs were present in lower proportions. After parathyroidectomy, pruritus and myopathy reduced significantly, while pain in bones and joints remained. One patient had brown tumor at the maxillary bone that regressed gradually after parathyroidectomy. Significant decreases of phosphate and calcium levels were recorded in all but two patients on the very first postoperative day. Regular peroral and parenteral supplementations of calcium and vitamin D metabolites were used, but calcemia was not normalized until the end of the third week of the postoperative period. Serum alkaline phosphatase showed an increase after the surgery, thereupon a sudden and then slower decrease up to 1 year from the surgery. Plasma iPTH levels, checked on the 21st postoperative day, were close to the lower normal limit in all but two (4.3%) patients with persistent SHP, who required reoperation. In conclusion, subtotal parathyroidectomy was proved as a successful and safe treatment for patients with SHP resistant to medical therapy, and treatment was followed by improvement of clinical symptoms and metabolic disorders.
