Embolic events are the current predominant cause of maternal death (~20%) in the United States(1). They are also the most common cause of acute hemodynamic and respiratory collapse during pregnancy(2). Embolized materials during pregnancy include: thrombus, air, amniotic fluid, and trophoblastic tissue. While the risk factors, presentation, course, and prognosis are all somewhat different with these embolic events, they tend to follow a similar initial course with obstruction of the pulmonary vasculature and/or pulmonary outflow tract leading to V/Q mismatch and compromise of cardiac output through mechanical obstruction, release of vasoactive mediators - all of which ultimately result in clinically-significant hypoxemia. Additionally, a disseminated intravascular coagulation (DIC) picture may develop with either air or amniotic (especially prominent) embolism. In contrast to other embolic events, trophoblastic embolization uniquely carries the risk of malignant spread in any seeded tissue bed.
