[Primary hyperparathyroidism and pregnancy. Aspects of neonatal morbidity]

Primary hyperparathyroidism has to be accused to cause serious morbidity during pregnancy not only on the maternal, but also on the fetal side: the fetus is threatened by prematurity, dystrophy and an increased risk of stillbirth. Postpartually hypocalcaemia and tetany may be observed as the result of neonatal hypoparathyroidism caused by maternal and thus also fetal hypercalcaemia. We report the case of a 32-year-old pregnant woman suffering from a severe form of primary hyperparathyroidism caused by an adenoma of the parathyroidea. The tumor was removed in the 34. week of pregnancy. Six weeks later the patient delivered a healthy boy (birth weight 3450 g). A survey is given of the therapeutical procedures that should be arranged individually by interdisciplinary consulting depending on the degree of maternal disease and on the gestational age.
