Amniotic fluid embolism: a case with non-cardiogenic pulmonary edema.

We report an uncommon case of amniotic fluid embolism (AFE) in a 24-year-old woman with a 26th-week, second pregnancy. Clinical manifestations were dominated by acute respiratory distress and pulmonary edema. Recovery was complete. Early invasive hemodynamic studies showed normal function of the left ventricle with a low pulmonary artery occluded pressure. These findings are controversial to the concept of cardiogenic pulmonary edema in AFE.
