Acute hyperthyroidism during pregnancy: a case report and critical analysis.

A rare case of acute hyperthyroidism during pregnancy is described and the management is discussed. Prompt subtotal thyroidectomy may be superior to the use of antithyroid drugs in particular circumstances. Fetal outcome of hyperthyroid mothers is discussed in the light of recent long-term follow-up studies and immunogenetic data. Women considered to be hyperthyroid are at high-risk for obstetrical and neonatal problems: early diagnosis of this condition is of paramount importance.
