Abstract
Objective: To determine whether platelet aggregation analysis is predictive of periprocedual ischemic or hemorrhagic events in patients undergoing carotid artery stenting (CAS), preoperative platelet aggregation in 18 patients scheduled for CAS was analyzed.
Methods: Blood samples were obtained from patients just before measurement of platelet aggregation with adenosine-diphosphoric acid (ADP) and collagen. All patients received diffusion-weighted image (DWI) on MRI at 1-3 days after the procedure.
Results: Maximum platelet aggregation rate was statistically higher in patients with ischemic events. In contrast, there was no difference in the positive rate of asymptomatic high intensity spots on DWI.
Conclusion: Preoperative platelet aggregation correlated with periprocedual ischemic events after CAS.
