Impact of platelet transfusion on hematoma expansion in patients receiving antiplatelet agents before intracerebral hemorrhage

Abstract

This study suggests that platelet administration does not reduce the frequency of hematoma expansion in ICH patients receiving antiplatelet medications. This lack of efficacy may relate to transfusion timing, as a significant proportion of hematoma expansion occurs within 6 hours post-ictus. Additionally, the increased rates of hematoma expansion in the clopidogrel cohort may relate to its prolonged half-life. A larger, prospective study is warranted.
