Summary
Reoperative radioguided parathyroidectomy successfully treated persistent primary hyperparathyroidism. This approach, using Tc-99m sestamibi and a gamma probe, enabled precise localization and removal of a difficult-to-find parathyroid adenoma.
Area of Science:
- Endocrinology
- Surgical Oncology
- Nuclear Medicine
Background:
- Primary hyperparathyroidism can necessitate reoperative surgery when initial parathyroid explorations fail.
- Persistent hypercalcemia and symptoms underscore the need for effective re-exploration strategies.
Observation:
- A 58-year-old male patient presented with persistent hypercalcemia post-two prior parathyroid surgeries.
- Preoperative Tc-99m sestamibi scan identified a right inferior parathyroid adenoma, but localization remained challenging.
Findings:
- Reoperative radioguided parathyroidectomy utilized a hand-held gamma probe for intraoperative localization.
- Successful resection of an enlarged parathyroid gland located retroesophageally was achieved.
- Intraoperative parathyroid hormone testing confirmed a surgical cure, with the patient remaining disease-free.
Implications:
- Radioguided surgery combined with intraoperative parathyroid hormone testing is crucial for complex reoperative parathyroidectomy.
- This technique enhances the success rate for locating and removing aberrant or previously missed parathyroid adenomas.
- Offers a viable solution for patients with persistent primary hyperparathyroidism after multiple failed explorations.
