Disseminated intravascular coagulation (DIC) is an acquired disorder, in which activation of the coagulation-fibrinolysis system takes place. DIC has a very varied pathological state that is dependent on several factors, such as, underlying disorders, trigger of DIC and activation of intravascular coagulation. Accurate diagnosis of DIC is therefore needed to confirm the presence of an underlying disorder and clinical manifestations and to investigate blood coagulation and fibrinolytic activities. Rapid diagnosis and adequate therapy produce a successful recovery. In this paper, the variety of DIC is summarized.
