[Method and initial results of percutaneous ultrasound-controlled sclerotherapy of parathyroid adenoma in secondary or tertiary hyperparathyroidism]. / Methodik und erste Ergebnisse der perkutanen ultraschallgezielten Verödung von Nebenschilddrüsenadenomen bei sekundärem oder tertiärem Hyperparathyreoidismus.

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.
