Answer

Acute DIC occurs in obstetric calamities such as placental abruption (abruptio placentae) and amniotic fluid emboli. Amniotic fluid has been shown to be able to activate coagulation in vitro, and the degree of placental separation correlates with the extent of the DIC, suggesting that leakage of thromboplastinlike material from the placental system is responsible for the occurrence of DIC.
