A rare case of maternal foetal death caused by uterine rupture in the placenta accreta.

Background: Fetal death has various causes, among the most common are problems relating to the placenta, such as placental abruption or placental malformations such as placenta accreta. From the literature, it emerges that placental analysis at autopsy can allow for greater resolution of cases compared to clinical history and external examination of the fetus alone.
Case Report: We report the case of a woman at the eleventh week of pregnancy who died in hospital. The medical history revealed two further previous pregnancies, both with births by cesarean section. The autopsy identified the cause of maternal death as acute cardiorespiratory arrest secondary to hemorrhagic shock from spontaneous uterine rupture. Hemorrhagic infiltrate was found in the intervillous placental spaces with rupture of the uterus due to placenta previa and accreta.
Discussion: Placenta accreta is a condition in which a pathological adherence and/or invasion of the myometrium by the placenta is observed. This condition poses a problem during recovery with potential for severe bleeding. Therefore, we emphasize the macroscopic and histological analysis of the placenta, uterus and the ovaries in all cases of maternal-fetal death, suggesting however that the organs be analyzed both by gross analysis and after permanence in formaldehyde. Furthermore, in these cases, it is important to evaluate the clinical history and data, especially ultrasound scans performed in life, or insertion anomalies during instrumental investigations. For this reason, we recommend to collaborate with a multidisciplinary team in these cases, including the gynecologist and the forensic pathologist.
