title: Delayed presentation of amniotic fluid embolism: lessons from a case diagnosed at autopsy.
abstract: Amniotic fluid embolism (AFE) syndrome, a catastrophic cause of respiratory failure typically occurs during labour, or soon after delivery. Systemic hypotension is the most prominent haemodynamic alteration documented in patients with AFE, a consequence principally of severe left-sided heart failure. A 22-year-old female was admitted to the respiratory intensive care unit with severe eclampsia and acute respiratory failure 4 h following delivery. Her blood pressure was elevated (systolic 150-180 mm Hg, diastolic 90-110 mm Hg) throughout the admission. She succumbed in spite of therapy for eclampsia and mechanical ventilation. Autopsy revealed large numbers of polygonal, anucleate foetal squames and mucin in the pulmonary vasculature typical of AFE while changes of eclampsia were found in the liver and kidneys. It appears that AFE syndrome can have a delayed presentation, as late as 4 h after delivery and haemodynamic collapse may not be mandatory if the patient has coexisting systemic hypertension secondary to severe eclampsia.
