Summary
Radioguided parathyroidectomy effectively treated renal hyperparathyroidism in a case study. This technique, using a gamma probe, helped locate and remove all parathyroid glands, preventing recurrence.
Area of Science:
- Endocrinology
- Surgical Oncology
- Nuclear Medicine
Background:
- Renal hyperparathyroidism management remains challenging.
- Radioguided parathyroidectomy (RG P) shows promise for primary hyperparathyroidism.
- Its utility in renal hyperparathyroidism is not well-established.
Observation:
- A 55-year-old woman on hemodialysis with renal hyperparathyroidism underwent RG P.
- Preoperative ultrasonography identified three enlarged parathyroid glands.
- 99mTc-sestamibi injection guided the resection of two glands.
Findings:
- An intraoperative gamma probe detected residual radioactivity in the upper mediastinum.
- An ectopic parathyroid gland was located and removed from the anterosuperior mediastinum.
- Pathology confirmed parathyroid hyperplasia; no complications occurred.
Implications:
- RG P, aided by intraoperative gamma probe, can locate ectopic and supernumerary parathyroid glands.
- This technique may reduce persistent and recurrent hyperparathyroidism in renal cases.
- Successful 30-month follow-up suggests long-term efficacy.
