Brief Summary:
  • To prove whether use of antiplatelet agents results into a rapid enlargement of hematoma after onset of acute intracerebral hemorrhage.
  • To prove the efficacy and safety of platelet transfusion for prevention of hematoma growth in patients who were stricken by acute intracerebral hemorrhage while being on antiplatelet medication.

Condition or disease Intervention/treatment Phase
Intracerebral Hemorrhage Biological: platelets Not Applicable

Detailed Description:
  • Hematoma growth is a well-known powerful determinant of mortality and poor outcome after intracerebral hemorrhage.
  • Some observations suggest that previous use of antiplatelet agents associates with rapid hematoma enlargement and poor outcome after cerebral hemorrhage.
  • Immediate platelet transfusion for such patients may prevent hematoma growth but also cause thromboembolic complications.
