摘要
DIC is not a clinical entity in itself. Instead, it always occurs secondary to a broad spectrum of various diseases. DIC may be defined as an acquired syndrome characterized by the activation of intravascular coagulation up to intravascular fibrin formation. Although the trigger for the activation of the coagulation system may vary depending on the underlying condition, it is usually mediated by several cytokines. Thrombin generation proceeds via the (extrinsic) tissue factor/factor Ⅶ a route and simultaneous depression of inhibitory mechanisms, such as the protein C and protein S system. In addition, impaired fibrin degradation, dur to high circulating levels of PAI-1, contributes to enhanced introvascular fibrin deposition.
