A Role for Embolic Protection in the Management of Acute Limb Ischemia

Distal embolization is a complication during lower-extremity revascularization procedures that may occur when intervening on acute or subacute lesions. Several studies have demonstrated the safety and feasibility of using embolic protection devices (EPD) and some interventionalists have adapted this technology for use in infrainguinal revascularization procedures. At present, there are no randomized trials to indicate the benefit, safety, and cost-effectiveness of EPD for this application and its use in the United States is considered off-label. However, based on our experience and a review of the published literature, we consider the use of EPD in acute lower-extremity ischemia a reasonable strategy.
