Expanding Use of Embolic Protection Devices

Abstract

Embolic protection devices were initially developed for the treatment of saphenous vein aorto-coronary bypass graft stenosis due to the significant risk of atheroembolism, and their use is well accepted. The use of these devices for carotid arterial interventions is also well accepted due to the significant consequences of embolization in the cerebral circulation. The use of these devices is extending to other vascular beds to include the renal arteries and lower extremities. We review the basic principles of these devices and their uses in various vascular beds based on our own experience as well as that in the literature.
