  • 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.

Further study details as provided by University of Oulu:

Primary Outcome Measures:
  • Hematoma growth within 24 h measured as increase in hematoma volume observed by head CT [ Time Frame: 24 hours ]

Secondary Outcome Measures:
  • Glasgow Outcome Score [ Time Frame: 90 days ]
  • Cardiovascular death occurring within the treatment period [ Time Frame: 90 days ]
  • Death due to any cause occurring within the treatment period [ Time Frame: 90 days ]
  • Acute myocardial infarction [ Time Frame: 90 days ]
  • Venous thromboembolism [ Time Frame: 90 days ]

Estimated Enrollment: 100
Study Start Date: January 2009
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Platelet transfusion
Biological: platelets
Four units of fresh platelets will be infused immediately
No Intervention: 2
No platelet transfusion

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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
