[Fibrin clots in placental vessels in intrauterine shock (author's transl)].

In 56 placentas there were fibrin clots in the vessels of the chorionic plate and the stem villi. Fifty infants survived. The fibrin clots in the relatively large placental vessels are considered to be the result of intrauterine shock. A similar pathogenetic concept is postulated as in the well-known diseminated fibrin thromboembolism which is evident in the visceral organs of children who died in the perinatal period. This identification of these fibrin clots in the vessels of the stem villi, especially in cases of so-called risk deliveries, allows the risk for newborn to be determined during their first days of life (hyaline-membrane disease, hemorrhagic diathesis, etc.). One can testify the intrauterine shock by these findings, even in newborn who survive the respiratory distress syndrome.
