  • Title: Parathyroid autotransplantation in forty-four patients with primary hyperparathyroidism: the role of thallium scanning.
    Author: McCall AR, Calandra D, Lawrence AM, Henkin R, Paloyan E.
    Journal: Surgery; 1986 Oct; 100(4):614-20. PubMed ID: 3764687.
    Abstract:
    Forty-four patients with primary hyperparathyroidism were followed for 18 to 126 months after subtotal or total parathyroidectomy and parathyroid autotransplantation. Indications for autotransplantation included the devascularization of parathyroid glands during concomitant thyroid lobectomy or total thyroidectomy and the excision of the only remaining parathyroid tissue in patients with persistent hyperparathyroidism after previous unsuccessful parathyroidectomies. Before implantation, all parathyroid tissue was histologically evaluated by frozen-section light microscopy with hematoxylin and eosin stain. Fifteen patients had histologically normal implants; to date none of these patients have developed recurrent hyperparathyroidism. Twenty-nine patients had either adenomatous or hyperplastic parathyroid tissue used for implants; two of these patients developed graft-dependent recurrent hyperparathyroidism 4 and 7 years later. In both patients the grafts were preoperatively localized by thallium scanning and their resection restored eucalcemia. One hundred thirty-one patients from 11 series in the current literature had a cumulative incidence of 17.5% for presumed graft-dependent recurrence and a 9.2% incidence of graft excision followed by eucalcemia. In comparison, in the present series the incidence of graft-dependent recurrent hyperparathyroidism in patients with either adenomatous or hyperplastic implants stands at 6.9%. In contrast, in 15 patients with normal parathyroid tissue implants, the incidence was zero.
