Parathyroid autotransplantation in primary parathyroid hyperplasia.
Four patients with primary parathyroid hyperplasia were treated by total parathyroidectomy and autotransplantation of parathyroid tissue into the forearm muscle. All patients remained normocalcemic after vitamin D and oral calcium replacement therapy were stopped at 1 1/2, four, nine and 13 months, respectively. Graft function was documented further by detection of a higher concentration of parathyroid hormone in plasma from the basilic vein draining the graft bed than from the basilic vein in the contralateral arm. Intravenous calcium infusion suppressed parathyroid hormone secretion from the graft whereas hypocalcemia induced by ethylenediaminetetra-acetic acid markedly stimulated hormone release. In two patients histologic examination of a grafted fragment revealed hyperplastic parathyroid tissue. This method of treatment offers a suitable alternative to radical subtotal parathyroidectomy in selected patients with hyperparathyroidism.
