RESUMO
Throughout the last century, there has been a marked decline in obstetric maternal deaths, resulting in an increase in the proportion of nonobstetric deaths among pregnant women. Trauma, in particular, has become a leading cause of maternal death. We report the case of a 20-year-old primigravid woman who was involved in a motor vehicle crash at 36 weeks gestation. The woman developed abruptio placentae, followed by disseminated intravascular coagulation, adult respiratory distress syndrome, and shock, and died the day after the crash. Widespread pulmonary embolization by chorionic villi was identified at autopsy. This report discusses traumatic maternal deaths, with emphasis on the differences in injury pattern observed in pregnant trauma victims in comparison with other adults. It is important that the pathologist be aware of these problems so that an accurate cause of death can be identified in cases of maternal death after trauma. Also discussed is the relationship between trauma and placental abruption and the mechanism of death in the patient. To the authors' knowledge, this is the first reported case of extensive embolism of chorionic villi to the lungs after trauma.
