7.06 Carotid Artery Stenosis

In this episode, we review carotid artery stenosis (CAS), including its presentation, diagnosis, medical management, and intervention. Do dizziness, presyncope, or syncope count as symptomatic CAS? What is the definition of nondisabling stroke and transient cerebral ischemic symptoms? What risk factors permit ordering a carotid duplex ultrasound before coronary artery bypass graft surgery? What peak systolic velocity on ultrasound correspond to >=50% and >=70% stenosis of a carotid artery? What antiplatelet regimen is recommended for CAS? In patients with symptomatic CAS, in what time window after the non-disabling stroke or TIA should you perform revascularization? Is there any role for revascularization of severe CAS that is asymptomatic? Tune in for answers to these questions.
