Summary

Ultrasonography-guided ethanol or calcitriol injections can reduce enlarged parathyroid glands in secondary hyperparathyroidism. While effective, parathyroidectomy remains the optimal treatment for renal hyperparathyroidism.

Area of Science:

  • Nephrology
  • Endocrinology
  • Interventional Radiology

Background:

  • Advanced secondary hyperparathyroidism is a common complication in uremic patients.
  • Enlarged parathyroid glands contribute to the pathophysiology of this condition.
  • Current treatment options have limitations.

Purpose of the Study:

  • To evaluate percutaneous direct injection of ethanol, calcitriol, and analogues into parathyroid glands as a therapeutic option.
  • To assess the efficacy of these minimally invasive procedures for mass reduction of hyperplastic parathyroid glands.
  • To investigate the potential of maxacalcitriol injection to induce parathyroid cell apoptosis.

Main Methods:

  • Percutaneous direct injection of ethanol, calcitriol, and analogues.
  • Guidance by ultrasonography for precise parathyroid gland targeting.
  • Assessment of indications and limitations of the injection therapies.

Main Results:

  • Successful mass reduction of enlarged parathyroid glands was achieved through direct injection.
  • Maxacalcitriol injection demonstrated potential in inducing apoptosis of parathyroid cells.
  • The indications and limitations of these interventional therapies were established.

Conclusions:

  • Percutaneous direct injection therapies offer a viable option for managing enlarged parathyroid glands in secondary hyperparathyroidism.
  • While these minimally invasive techniques show promise, parathyroidectomy remains the most successful treatment for severe renal hyperparathyroidism.
