Flow Cytometry Based Platelet Reactivity Testing to Predict the Occurrence of Per-operative Solid Microemboli During Carotid Endarterectomy.

Objective: Peri-operative antiplatelet therapy (APT) aims to prevent thrombotic events such as stroke. High platelet reactivity ,despite the use use of APT, increases the risk of thrombotic events. Transcranial Doppler imaging (TCD) is used to detect peri-operative microembolic signals (MES) during carotid endarterectomy (CEA).
