Peripheral Vascular Disease refers to narrowing and hardening of the arteries that supply the legs and feet.

• A. Peripheral Vascular Disease
• B. Venous insufficiency
• C. Varicose veins
• D. Deep vein thrombosis

Answer: (A)

Peripheral vascular disease describes arterial disease where the arteries that supply the legs and feet become narrowed and stiff from atherosclerosis, reducing blood flow to the tissues. This arterial problem matches the idea of narrowing and hardening of the arteries feeding the legs. The other options involve veins rather than arteries: venous insufficiency means poor venous return causing swelling and fatigue; varicose veins are enlarged superficial veins from valve failure in the veins; deep vein thrombosis is a blood clot in the deep venous system causing swelling and pain. So the description given fits PVD, an arterial condition affecting leg perfusion.
