During carotid artery stenting (CAS), atheroemboli may arise from the aorta, arch, and ipsilateral carotid artery. Embolic protection devices (EPD) are designed to decrease the risk of stroke resulting from atheroembolization from the ipsilateral carotid artery during CAS; double (proximal and distal) EPDs may decrease the risk of stroke in high-risk patients and lesions. Further studies are needed to determine if double EPDs are superior to single EPDs or other devices.
