The surgical removal of all or part of a limb.
Contrast media is injected into arteries to show blood flow on X-ray in order to diagnose blockages.
A procedure in which a balloon is used to open narrowed or blocked arteries. It is not designed to remove plaque.
ABI is a non-invasive blood pressure measurement used to diagnose Peripheral Artery Disease.
A procedure to remove blockages and open up an artery. May be followed by angioplasty once the blockage is reduced.
Build-up of fatty substances, cholesterol, cellular waste products and calcium in the inner lining of an artery, which can build up and reduce blood flow through an artery. Often referred to as “hardening of the arteries.”
A tube used for gaining access to one of the body’s cavities or blood vessels.
A procedure in which small, flexible catheters are inserted into the arteries to enable various measurements and visualize the arteries through the use of X-ray dye.
A condition caused by ischemia of the muscles, which results in pain in the hips, buttocks or legs, usually during an activity such as walking.
Blockage of the coronary arteries.
The sustained, severe decrease in arterial blood flow to the leg, resulting in rest pain, ulcer, gangrene and potentially limb loss.
The use of light from the excimer laser to produce photoablation-ultraviolet energy delivered through a catheter directly to the obstruction in the artery, vaporizing the blockage into tiny particles.
An action or ministration that produces an effect or that is intended to alter the course of a physiologic process.
The inadequate flow of blood.
Laser Angioplasty for Critical Limb Ischemia (Clinical Trial).
An acronym for Light Amplification by Stimulated Emission of Radiation.
An atherosclerotic blockage in an artery; also known as plaque. A lesion may be stenosis (incomplete blockage) or an occlusion (a total blockage).
The form and structure of the component found within the artery. Atheroma, fibrosis, thrombus and calcium are four morphologies that in various composition lead to peripheral arterial blockages.
The inner open space or cavity of a tubular organ, as of an artery.
Complete blockage of an artery.
A narrowing of vessels that carry blood to the legs, arms, stomach or kidneys.
Renarrowing of an artery following an interventional procedure.
A condition in which the body is fighting a severe infection that can be caused by a number of different microbes, including bacteria, viruses and fungi.
Excimer laser that produces light in the blue spectrum of the ultraviolet range at a wavelength of 308 nanometers. Similar to a LASIK excimer laser used in eye surgery, which operates at 193 nanometers in the cooler, ultraviolet spectrum of light.
A narrowing of an artery.
A blood clot that breaks loose and is carried away by the bloodstream to plug another vessel.
Through a vein or through the venous system, as in the passage of a device or catheter through a vein for diagnostic or therapeutic purposes.
