Peripheral arteries are the blood vessels that transport oxygenated blood from the heart to all other tissues and organs throughout the body, including the brain, limbs, and abdominal organs. Peripheral Artery Disease (PAD) is a condition characterized by the narrowing of these arteries, most commonly due to atherosclerosis. Atherosclerosis involves the buildup of fatty deposits (plaque) within the artery walls, leading to hardening and restricted blood flow. This reduced blood supply prevents the affected tissues and organs from receiving adequate oxygen and nutrients. PAD typically progresses slowly and can manifest with various complications affecting different body parts. The carotid arteries, as well as arteries supplying the kidneys, intestines, and legs, are particularly susceptible to this condition.
