Critical limb ischemia, or simply limb ischemia, is the restriction of blood flow and loss of tissue oxygenation to the legs, feet, or hands. It occurs when blood flow to the limbs is blocked. Limb ischemia can result in tissue death from lack of oxygen and nutrients.

Common Causes of Limb Ischemia
Limb ischemia is a sign of advanced peripheral artery disease caused by a buildup of plaque in your blood vessels. The plaque makes it harder for blood to flow through to your limbs.
Limb Ischemia Symptoms
Symptoms of limb ischemia may include:
- Shiny, pale skin compared to the rest of the body
- Pain during movement or at rest
- Skin temperature cooler than the rest of the body
- Feeling of pins and needles
- No or weak pulse in the affected limb
- Thickened toenails
- Skin infections and sores that do not heal
Preventing Limb Ischemia
If you have peripheral artery disease, follow your treatment plan to help prevent limb ischemia. Keep a close watch for symptoms of limb ischemia to identify the problem before it becomes too severe.
