Parathyroid allotransplantation, in which the parathyroid glands from the donor are transplanted into the recipient to function, is used in patients with total parathyroidectomy or with permanent hypoparathyroidism after thyroid surgery to prevent possible severe hypocalcemia. There are two methods of parathyroid allograft transplantation: 1. the donor’s side of the thyroid and parathyroid glands, together with the arterial and venous vessels, are anastomosed to the recipient’s femoral triangle vessels and then transplanted intra-abdominally, with the need for postoperative application of immunosuppressive drugs. 2. The parathyroid glands removed from the donor are irradiated with cobalt-60 to reduce immunogenicity, and then transplanted into the recipient’s forearm muscle after in vitro culture. Serum calcium ions and parathyroid hormone levels need to be tested regularly after the transplantation procedure. The transplantation is successful and the patient has a significant increase in parathyroid hormone levels about one month after the operation. If you experience discomfort after parathyroid allograft transplantation, seek medical attention promptly to avoid delays.
