The syndrome of disseminated intravascular coagulation (DIC) is an acquired coagulation disorder which is characterized by a significant activation of haemostasis and the formation of intravascular microthrombi, the consumption of coagulation factors and activation of fibrinolysis. DIC has similar clinical stages and a similar laboratory picture, regardless of the causal factor. The diagnosis of DIC should be based on anamnestic, clinical and laboratory data. The laboratory diagnosis of DIC is possible by using relatively simple tests, which have the character of statim examinations. DIC treatment is based on the principle of treatment of the cause, discontinued consumption of haemostatic material, substitution of lacking factors and restoration of the microcirculation. The possible development of DIC must be taken into account in a number of acute conditions, in particular the development of shock syndrome. The presented article summarizes some views on causes, diagnosis and possible treatment of DIC.
