Summary
Trauma is a leading cause of maternal death. This case report details a fatal motor vehicle crash in a pregnant woman, highlighting pulmonary embolism by chorionic villi as a rare complication.
Area of Science:
- Obstetrics and Gynecology
- Trauma Surgery
- Forensic Pathology
Background:
- Maternal mortality has shifted towards non-obstetric causes, with trauma emerging as a significant factor.
- Understanding injury patterns in pregnant trauma patients is crucial for accurate diagnosis and management.
Observation:
- A 20-year-old primigravid woman at 36 weeks gestation died following a motor vehicle crash.
- Complications included abruptio placentae, disseminated intravascular coagulation, adult respiratory distress syndrome, and shock.
Findings:
- Autopsy revealed widespread pulmonary embolization by chorionic villi, a previously unreported finding after trauma.
- The case underscores the unique injury patterns and potential mechanisms of death in pregnant trauma victims.
Implications:
- Pathologists must be aware of specific challenges in determining cause of death in maternal trauma cases.
- This case highlights the critical relationship between trauma, placental abruption, and fatal outcomes due to embolism.
