The treatment of primary hyperparathyroidism during pregnancy.

Data on the management of primary hyperparathyroidism during pregnancy are sparse and relatively few parathyroidectomies have been performed during pregnancy. Provided the diagnosis can be established with reasonable certainty, removal of a parathyroid adenoma should be undertaken during the second or at the beginning of the third trimester. Parathyroidectomy in the hands of a surgeon familiar with this operation carries few risks. The complication rate of untreated cases may reach 80 per cent and include spontaneous abortion, fetal death and neonatal tetany. We present two cases of pregnant women who underwent successful parathyroidectomy during the course of gestation.
