Embolic protection in infrainguinal interventions

The benefits of the use of embolic protection devices (EPDs) in saphenous vein coronary artery bypass grafts and carotid arteries have been shown, but the utility of their application during infrainguinal endovascular interventions is somewhat unclear. Patients with specific anatomical features or lesion characteristics, or patients undergoing specific types of endovascular interventions may benefit from the off-label use of EPDs, but this has yet to be determined. This report will examine the current literature related to the use of EPDs in infrainguinal endovascular interventions and attempt to identify the patients who would most likely benefit from their use. In addition, the setting in which EPDs have been used at one institution is briefly described. This discussion will serve as a general guideline for the use of EPDs and act as an impetus for the development of future clinical trials to help elucidate the patients who will truly benefit from EPDs use when undergoing lower extremity endovascular revascularization procedures.
