embolic protection device
Also written as: EPD — Embolic Protection Device
Temporary filtration or occlusion system used to prevent distal embolization during vascular interventions.
Full Definition
Embolic protection devices (EPDs) are specialized instruments designed to capture or redirect embolic debris that may be dislodged during endovascular interventions, preventing downstream vascular occlusion. These devices include distal occlusion balloons, filter wires, and proximal protection systems. EPDs are particularly important during carotid artery stenting, saphenous vein graft interventions, and procedures in vessels with high plaque burden. The selection of appropriate embolic protection depends on vessel anatomy, lesion characteristics, and procedural approach. Proper deployment and retrieval techniques are critical for device effectiveness and patient safety.
Usage
Usage note: Specify the type of protection device used (filter, balloon, or proximal protection).
