Disseminated Intravascular Coagulation Causes and Pathophysiology in Platelet Disorders
Disseminated Intravascular Coagulation (DIC) is a consumptive coagulopathy characterized by the pathological activation of the clotting cascade throughout the vasculature, resulting in widespread microthrombi formation that depletes platelets and clotting factors while simultaneously inducing hemorrhage. The core mechanism involves primary etiologies—such as obstetric complications, sepsis, malignancies like acute promyelocytic leukemia, or snake bites—that trigger excessive thrombin generation via tissue factor exposure or endotoxin release, ultimately causing microangiopathic hemolytic anemia and elevated D-dimers due to unregulated fibrinolysis.
