In 1989, Kawakami discovered that the coagulation and fibrinolysis systems were both excessively activated in chronic subdural hematoma. [8] This results in defective clot formation and recurrent hemorrhage. Katano et al reported that elevated concentrations of tissue plasminogen activator are found in some chronic subdural hematomas, and indicate a relatively high probability of recurrence. [9]
