Abstract

Coagulation, fibrinolysis and kinin-kallicrein system disorders could explain chronic subdural hematoma pathophysiology. The marked decrease in antithrombin III in the hematoma suggest that the decreased levels of clotting factors were caused by excessive coagulation resulting in clotting factors consumption. The decrease in alpha 2-antiplasmin with the increase of fibrin degradation products suggest that hyperfibrinolytic activity of the subdural hematoma. Coagulation and fibrinolysis disorders could explain repetitive hemorrhages from the outer membrane, which cause progressive enlargement of the hematoma. Kinin-kallicrein system disorders raise the hemorrhage by its action on the outer membrane. Nowadays, the earliest osmotic theory should reasonably be abandoned.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
