Background: A 27-year-old primigravid woman with a triamniotic pregnancy presented with preterm labor at 29 weeks of gestation and acute severe pulmonary edema after treatment with atosiban.
Case report: The severe symptoms and hypoxemia of the patient led to emergency hysterotomy and intensive care unit hospitalization.
Conclusions: This clinical case prompted us to review the existing literature to examine studies on differential diagnoses in pregnant women with acute dyspnea. The possible pathophysiological mechanisms of this condition and the management of acute pulmonary edema are worth discussing.
