What Is Leg Ischemia

Critical limb ischemia (CLI) is a severe blockage in the arteries of the lower extremities, which markedly reduces blood-flow. It is a serious form of peripheral arterial disease, or PAD, but less common than claudication.

What causes ischemia in leg?

Limb ischemia is most often caused by peripheral artery disease (PAD), a type of peripheral vascular disease caused by hardening of the arteries, or atherosclerosis. In the beginning stages of PAD, plaque builds up in your blood vessels and starts sticking together.

What are ischemic leg symptoms?

• Dry gangrene on the legs or feet – black, dry skin.
• Numbness or pain in the feet.
• Severe leg pain.
• Skin on the feet and legs that is smooth, shiny and dry.
• Sores or infections that won’t heal.
• Thickening toenails.
• Weak or no pulse in the feet or legs.
