[A case of fatal amniotic fluid embolism]

A 31-year-old pregnant woman (multipara), who was near the expected date of birth, was found dead in the joint flat by her partner. She was lying beside the bed and showed burns on the front of the body caused postmortem by contact with a radiator. Autopsy revealed a rupture of the fetal membranes, the inner layers of the uterus and a large vein. After centrifugation, the supernatant of the blood from the right half of the heart was turbid and contained small corpuscular amniotic fluid components. The diagnosis of amniotic fluid embolism could be confirmed histologically. In the pulmonary vessels of the mother meconium, lanugo hairs and epidermic scales could be demonstrated; in addition the fetal horny lamellae were confirmed immunohistochemically (using monoclonal antibody against cytokeratin).
