Clinical significance of platelets activation in patients with acute cerebral hemorrhage / 临床神经病学杂志

ABSTRACT

Objective To study the platelets activation in patients with acute cerebral hemorrhage and its significance in perihematoma edema.Methods 33 patients with cerebral hemorrhage were treated with minimally invasive surgery.The volume of edema perihematoma was determined by CT technique before operation.The expressions of platelets CD62p and TSP in intracerebral hematoma fluid and venous blood were detected by flow cytometry(FCM).The correlation between the two variables was also analyzed.Results The expressions of platelets CD62p and TSP were higher in patients with acute cerebral hemorrhage than those in healthy individuals,and the expressions of platelets CD62p and TSP in intracerebral hematoma fluid were higher than those in venous blood.There were significant positive correlations between the expression levels of CD62p and TSP from the surface of platelets in hematoma and the edema size perihematoma(CD62pr=0.4781,TSPr=0.5183,all P
