RESUMO
While admitted for management of hyperemesis gravidarum and preeclampsia, a 29-year-old gravida 1 para 0 patient with type 1 diabetes mellitus developed acute shortness of breath at 24 weeks gestation. Physical examination and chest X-ray findings were consistent with pulmonary edema, which in pregnancy is most often a severe complication of preeclampsia warranting delivery. The case is discussed with respect to diagnosis and management of pulmonary edema and acquired pulmonary hypertension in pregnancy, including timing and mode of delivery. Many case studies and guidelines advise caution when embarking on pregnancy with primary pulmonary hypertension; however, there is little available to guide clinical management when pulmonary hypertension secondary to fluid overload and preeclampsia develops during pregnancy.
