[Thyroid dysfunctions and pregnancy].
OBJECTIVE
To study thyroid dysfunctions during pregnancy.


METHODS
Descriptive, transversal and retrospective study of 61 thyroid dysfunctions during pregnancy, from January 1982 to December 2002.


RESULTS
There were 44 hyperthyroidism (1 in 1,908 deliveries: 0.05%) and 17 hypothyroidism (1 in 4,939: 0.02%). Main findings in hyperthyroid patients were: 30-34 years and 2 gestations (34.11%), arterial hypertension (15.90%), abortions (9.09%), preterm delivery (9.09%), term delivery (56.82%), cesarean section (25%), medical treated (97.78%), fetal weighs 3,000-3,499 g (25.61%), 1 and 5 minutes Apgar 8-10 points (60.54 and 81.59%), perinatal mortality rate 0.07 per 1,000 and there was no maternal mortality. And in hypothyroid women: 25-29 years (64.72%), one gestation (29.44%), abortions (17.64%), premature rupture of membranes and oligoamnios (17.64%), term delivery (35.28%), medical treated (100%), fetal weighs 2,500-2,999 g (56.25%), 1 and 5 minutes Apgar 8-10 points (78.58% and 78.58%) and there was no preterm delivery and perinatal or maternal mortality.


CONCLUSIONS
Thyroid dysfunctions are infrequent in pregnancy and have little repercussions in perinatal morbidity and mortality.
