[Method and initial results of percutaneous ultrasound-controlled sclerotherapy of parathyroid adenoma in secondary or tertiary hyperparathyroidism].

In 16 of 96 patients with clinical, roentgenological and biochemical signs of hyperparathyroidism due to chronic renal failure the parathyroid adenomas were detected ultrasonographically. Verification of the adenoma was done using fine-needle biopsy and cytological evaluation. In 8 patients an ultrasonographic-guided sclerotherapy using absolute ethanole was performed. The efficacy of this method was evaluated by control of the biochemical parameters. In all cases a reduction of the serum calcium level and of the parathormone was observed. This method may represent an adjuvant therapy in the treatment of renal hyperparathyroidism.
