Summary
A rare case of acute hyperparathyroidism occurred post-cardiac surgery. Surgical removal of a parathyroid adenoma resolved hypercalcemia and prolonged QT interval.
Area of Science:
- Cardiology
- Endocrinology
- Surgical Oncology
Background:
- Coronary artery bypass grafting (CABG) is a common cardiac surgery.
- Postoperative complications can include electrolyte imbalances and cardiac rhythm disturbances.
- Hyperparathyroidism is a condition characterized by excessive parathyroid hormone production.
Observation:
- A 64-year-old woman developed acute hyperparathyroidism within a week of CABG.
- She presented with hypercalcemia and a prolonged QT interval on electrocardiogram.
- Neck exploration identified a parathyroid adenoma in the lower right gland.
Findings:
- The parathyroid adenoma was surgically removed (parathyroidectomy).
- Post-surgery, the patient experienced rapid clinical improvement.
- Laboratory values, including calcium levels, returned to normal.
Implications:
- This case highlights a rare but significant complication of cardiac surgery.
- Early diagnosis and surgical intervention are crucial for managing acute hyperparathyroidism.
- Parathyroidectomy can effectively resolve hypercalcemia and associated cardiac issues.
