    Abstract:
    HYPOTHESIS: Hypercalcemic crisis is a rare complication of severe calcium intoxication usually caused by sporadic primary hyperparathyroidism that requires prompt diagnosis and definitive surgical treatment. Parathyroidectomy is essential for long-term successful treatment of hypercalcemic crisis. DESIGN: Retrospective case series. SETTING: Tertiary referral center. PATIENTS: Forty-three patients treated for hypercalcemic crisis during a 35-year period who had signs and symptoms of acute calcium intoxication and serum calcium levels of 15 mg/dL (3.75 mmol/L) or greater. MAIN OUTCOME MEASURES: Operative success, operative failure, and disease recurrence after surgery. Kaplan-Meier analysis was used to estimate long-term survival after parathyroidectomy. RESULTS: Forty-two (98%) of 43 patients were eucalcemic after initial parathyroidectomy. There was 1 postoperative death. Of 27 patients with postoperative calcium data available for 6 months or longer, operative success was achieved in 26 (96%). There was 1 operative failure in a patient with multiglandular disease requiring reoperation. There were 3 recurrences (7%) at 7, 58, and 265 months. Overall median survival after parathyroidectomy was 11.7 years (95% confidence interval, 9.2-NE [not estimable]). The mean +/- SD serum calcium level of this group at a median follow-up of 4 years after surgery was 9.1 +/- 0.9 mg/dL (2.28 +/- 0.23 mmol/L). CONCLUSION: Hypercalcemic crisis can be successfully treated by parathyroidectomy with continued normal parathyroid function and excellent long-term survival.
