Parathyroid autotransplantation.

7 patients with diffuse parathyroid hyperplasia underwent total parathyroidectomy and microsurgical autotransplantation for diffuse parathyroid hyperplasia. 5 of 7 patients showed good function of the grafted parathyroid tissue, as checked by the separate PTH assay from the grafted versus not grafted forearm. In 1 patient parathyroid stimulation test with EDTA infusion and suppression test with calcium infusion were also performed.
