Young et al: Surgical description and outcome of ultrasound‐guided minimally invasive parathyroidectomy in 50 dogs with primary hyperparathyroidism
Veterinary Surgery 1, 2023

🔍 Key Findings

  • Short-term resolution of hypercalcemia occurred in 97.8% (44/45) of dogs.
  • Long-term cure rate was 93.3%, comparable to traditional bilateral neck exploration.
  • Postoperative hypocalcemia was observed in only 15.6%, which is lower than traditional approaches (36–63.8%).
  • Permanent hypocalcemia occurred in 4.4%, requiring lifelong calcitriol supplementation.
  • Minimally invasive approach had median surgical times of 26 min (unilateral) and 45.5 min (bilateral).
  • Most lesions were adenomas (54.8%), followed by hyperplasia (27.4%) and carcinomas (3.2%).
  • Ultrasound identified 98.4% (61/62) of abnormal glands, supporting it as the preferred imaging modality.
  • One death due to non-compliance with calcitriol, emphasizing importance of postoperative management.
