Glossary


Amputation
The surgical removal of all or part of a limb.
Angiogram
A process when dye is injected into arteries to show blood flow on x-ray in order to diagnose blockages in arteries.
Ankle-Brachial Index (ABI)
ABI is a non-invasive blood pressure measurement used to diagnose Peripheral Artery Disease.
Angioplasty
A procedure in which a balloon is placed inside the narrowed artery and inflated to push the blockage against the arterial walls, opening narrowed or blocked arteries and improving blood flow. It is not designed to remove plaque.
Atherectomy
A procedure to remove blockages and open up an artery to restore or improve blood flow. May be followed by angioplasty once the blockage is reduced.
Atherosclerosis
A 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."
Catheter
A tiny tube used for gaining access to one of the body's cavities or blood vessels.
Catheterization
A procedure in which small flexible catheters are inserted into the arteries to enable various measurements and to visualize the arteries through the use of x-ray dye.
Claudication
A condition caused by ischemia (a restriction of the blood supply) of the muscles that results in leg pain, usually during an activity such as walking, or when at rest. Sometimes referred to as restless leg syndrome.
Critical Limb Ischemia (CLI)
The sustained, severe decrease of blood flow to the leg which results in rest pain, ulceration and eventual limb loss if left untreated.
Intervention
An action or ministration that produces an effect or that is intended to alter the course of a physiologic process.
Ischemia
The inadequate flow of blood.
Lesion
A blockage in a blood vessel; also known as plaque or stenosis.
Occlusion
Blockage of an artery.
Peripheral Artery Disease (PAD)
A form of Peripheral Vascular Disease where fatty deposits build up in the inner linings of artery walls. The build up restricts blood circulation resulting in blockage of the leg arteries.
Peripheral Vascular Disease (PVD)
A narrowing of vessels that carry blood to the legs, arms, stomach or kidneys.
Restenosis
Re-narrowing of an artery following an interventional procedure.
Stenosis
The narrowing of an artery.
Thromboembolic
A blood clot that breaks loose and is carried away by the blood stream to plug another vessel.
