Percutaneous intentional extraluminal revascularization

Percutaneous intentional extraluminal revascularization (PIER) is a technique used in interventional radiology to treat lower limb ischemia due to long superficial femoral artery occlusions. A guide wire is intentionally introduced in the subintimal space, after which balloon dilatation is performed to create a new lumen for the blood to flow through.
