Pseudogout associated with primary hyperparathyroidism: management in the immediate postoperative period for...

Three cases of pseudogout associated with primary hyperparathyroidism are reported. Preoperative radiological studies revealed association of pseudogout. Considering the frequent development of acute pseudogout attack following parathyroidectomy, prevention of a sudden decrease in the serum calcium concentration was attempted using calcium supplement therapy starting on the first postoperative day in all three cases. Serum calcium slowly decreased to the normal range, and the postoperative courses were uneventful. From these experiences, we advocate that calcium supplement therapy is worth trying for the prevention of acute pseudogout attack following parathyroidectomy.
