Your arteries carry blood rich in oxygen and nutrients from your heart to the rest of your body. When the arteries in your legs become blocked, your legs do not receive enough blood or oxygen, and you may have a condition called peripheral artery disease (PAD), sometimes called leg artery disease.
PAD can cause discomfort or pain when you walk. The pain can occur in your hips, buttocks, thighs, knees, shins, or upper feet. Leg artery disease is considered a type of peripheral arterial disease because it affects the arteries, blood vessels that carry blood away from your heart to your limbs. You are more likely to develop PAD as you age. One in 3 people age 70 or older has PAD. Smoking or having diabetes increases your chances of developing the disease sooner.
The aorta is the largest artery in your body, and it carries blood pumped out of your heart to the rest of your body. Just beneath your belly button in your abdomen, the aorta splits into the two iliac arteries, which carry blood into each leg. When the iliac arteries reach your groin, they split again to become the femoral arteries. Many smaller arteries branch from your femoral arteries to take blood down to your toes.
