Peripheral vascular disease
Extracted from the Wikipedia article Peripheral artery disease.
Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means the arteries are narrowed or blocked—the vessels that carry oxygen-rich blood as it moves from the heart to other parts of the body. Peripheral veinous disease, on the other hand, refers to problems with veins—the vessels that bring the blood back to the heart.
