    Reoperation for persistent hyperparathyroidism can be successful with advanced imaging. Aggressive localization techniques improve surgical planning and outcomes, though postoperative hypocalcemia requires management strategies like parathyroid autotransplantation.

    Area of Science:

    • Endocrinology
    • Surgical Oncology
    • Radiology

    Background:

    • Persistent hyperparathyroidism presents a significant surgical challenge, often requiring reoperation after multiple prior unsuccessful procedures.
    • Effective preoperative localization is crucial for successful surgical management of recurrent or persistent hyperparathyroidism.

    Purpose of the Study:

    • To evaluate the utility of various preoperative imaging modalities in localizing persistent hyperparathyroidism prior to reoperation.
    • To assess the success rate of reoperation in patients with persistent hyperparathyroidism.
    • To explore management strategies for postoperative hypocalcemia.

    Main Methods:

    • Retrospective analysis of 30 patients undergoing reoperation for persistent hyperparathyroidism.
    • Evaluation of preoperative arteriography, selective venous catheterization, and computerized axial tomography (CAT) for localization.

  • Assessment of surgical success based on postoperative calcium levels and management of hypocalcemia.

    • Main Results:

    • Preoperative arteriography aided surgical planning in 56% of cases and was retrospectively correct in 63%.
    • Selective venous catheterization provided localizing information in 83% of patients, correctly identifying the site or side in 60%.
    • Reoperation successfully rendered 83% of patients hypocalcemic or normocalcemic; 37% experienced profound hypocalcemia, managed with autografts or support.

    Conclusions:

    • Aggressive preoperative localization attempts are warranted for persistent hyperparathyroidism.
    • Advanced imaging techniques like arteriography and venous catheterization are valuable tools for surgical planning in reoperative hyperparathyroidism.
    • Cryopreserved parathyroid autotransplantation may be beneficial for managing long-term hypocalcemia following reoperation.
