AIM: To evaluate whether the presence of amniotic components in the maternal uterine vasculature could be a specific pathological indicator for amniotic fluid embolism (AFE).
METHODS: Medical records of patients treated between January 2006 and March 2013 were retrospectively examined to identify patients who underwent post-partum hysterectomy or autopsy due to maternal death. Three subjects with AFE with disseminated intravascular coagulation (DIC)-type post-partum hemorrhage (PPH), and 13 non-AFE subjects were included in analysis. Histochemical staining using hematoxylin-eosin (HE) and alcian blue, and immunohistochemical staining for sialyl-Tn were conducted to detect amniotic components in the maternal uterine vasculature.
RESULTS: Alcian blue was positive for amniotic components in the uterine vasculature of all subjects with AFE and of several subjects without AFE. Similarly, HE and sialyl-Tn were negative in some AFE subjects and positive in some non-AFE subjects.
CONCLUSIONS: The presence of maternal intravascular fetal material is not a specific indicator for AFE with DIC-type PPH. Therefore, the presence of fetal components in the uterine vasculature is unlikely to be a definitive indicator for AFE.
