Peripheral Artery Disease (PAD) and Related Ulcers

What is peripheral artery disease (PAD)?

Peripheral artery disease (PAD) is a narrowing or blockage of the blood vessels in the legs. Blood flow to your feet and legs is decreased. This decreased blood flow affects the health of your skin on your feet and legs. It can also be the reason a foot ulcer does not heal. People with PAD have an increased risk for heart attack and stroke. An estimated 8 million people in the USA have PAD.

How does blood circulate in the body? Blood flows through the body in arteries and veins. Blood carries oxygen through the arteries. Blood flows from the heart and lungs to the skin and to the tissues in the lower legs and feet. It provides them with the oxygen. All tissues need oxygen to stay healthy. Veins carry the used blood back to the heart and lungs to get more oxygen and food.

What causes peripheral artery disease?

  • Atherosclerosis, “hardening of the arteries” happens because the arteries become rough and narrow. Cholesterol and plaque block the artery.
  • Aneurysms
