Percutaneous intentional extraluminal revascularization is a percutaneous technique used in
interventional radiology for limb salvage in patients with
lower limb ischemia due to long
superficial femoral artery occlusions. This method is intended for those patients who make poor candidates for infrainguinal arterial
bypass surgery.
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.
The technique is not without complications but may serve as a "temporary bypass" to provide wound healing and limb salvage.
