Analysis of a case of generalized amniotic fluid embolism by demonstrating the fetal isoantigen (A blood type) in maternal tissues of B blood type, using immunoperoxidase staining.

A case of generalized amniotic fluid embolism, confirmed by staining fetal isoantigen in the maternal tissues, is reported. The distribution of emboli may be more accurately evaluated with the immunochemical staining technic than with standard hematoxylin and eosin stain. The severity of the embolic state is evaluated very exactly.
