What is arterial stenosis?
Arteries transport oxygenated blood to different tissues and organs of the body. This is essential for metabolic activities and sustaining life functions. Any narrowing of an artery will hamper the flow of blood and depending on the extent of the narrowing, known as stenosis, the artery may be partially or completely occluded (blocked).
Narrowing of an artery may not cause obvious signs and symptoms in the initial stages. If sufficient oxygenated blood is able to reach the target organs and tissues, the narrowing may go unnoticed for long periods of time. Diagnostic investigations like an angiogram may be the only way to identify the narrowing of an artery.
