26. Microembolic Risk of Carotid Artery Plaque Composition By MRI at the Time of Elective Revascularization

Current guidelines for management of carotid atherosclerosis, the predisposing factor for ischemic stroke, are based on degree of stenosis and presence of symptoms. Both carotid endarterectomy (CEA) and minimally invasive (CAS) procedures pose risks to the patient, including peri/post-operative stroke. Intracerebral microembolization is a major factor leading to stroke after surgical or percutaneous revascularization. The ability of transcranial Doppler (TCD) to detect intraoperative microembolization, diffusion-weighted brain MRI to detect microinfarct lesions, and carotid MRI to provide detailed information on plaque morphology make these powerful tools in determining embolic potential.
