Resumo

JUSTIFICATIVA E OBJETIVOS: A gonadotrofina coriônica humana (HCG) e o hormônio tireotrófico (TSH) apresentam analogia entre suas estruturas, assim como seus receptores. Os altos níveis de HCG encontrados nas doenças trofoblásticas gestacionais podem induzir um quadro de hipertireoidismo secundário. O objetivo deste relato é apresentar um caso em que a administração de contraste iodado precipitou um quadro de crise tireotóxica. RELATO DO CASO: Paciente com mola hidatiforme completa foi admitida no centro cirúrgico com sangramento vaginal intenso após realização de tomografia com contraste iodado. Durante indução anestésica, paciente apresentou quadro compatível com crise tireotóxica. CONCLUSÕES: A incidência de quadros graves associados à doença trofoblástica gestacional tende a diminuir com seu diagnóstico precoce. Ainda que isso aconteça, o anestesiologista deve estar atento à possibilidade de crise tireotóxica nesses pacientes.

Abstract

BACKGROUND AND OBJECTIVES: Human chorionic gonadotropin (HCG) and thyrotrophic hormone (TSH) have analogies in their structures, as well as in their receptors. The high levels of HCG seen in gestational trophoblastic diseases may induce secondary hyperthyroidism. The objective of this report was to present a case in which the administration of iodinated contrast triggered a thyrotoxic crisis. CASE REPORT: Patient with complete hydatidiform mole who was admitted to the operating room with severe vaginal bleeding after a tomographic exam with iodinated contrast. During anesthetic induction, the patient presented symptoms compatible with thyrotoxic crisis. CONCLUSIONS: The incidence of severe presentations associated with gestational trophoblastic disease tends to decrease with early diagnosis. Still, the anesthesiologist should be aware of the possibility of those patients developing thyrotoxic crisis.
