embolic protection device
A specialized catheter system designed to capture debris during intervention to prevent downstream embolization.
Full Definition
An embolic protection device (EPD) is a catheter-based system used during certain interventional procedures to capture atherosclerotic debris, thrombus, or other particulate matter that may be dislodged during treatment. These devices are particularly important in carotid artery stenting, saphenous vein graft interventions, and procedures involving friable or thrombus-containing lesions. EPDs work through various mechanisms including distal occlusion balloons, filter wires, or proximal occlusion systems. Their use has been shown to reduce the incidence of periprocedural stroke and other embolic complications, though they add complexity to the procedure and require specific training for optimal deployment.
Usage
Usage note: Specify the type of EPD used (filter, balloon, etc.) in procedure notes.
