Limb Ischemia

Limb ischemia means there is a lack of blood flow to a limb, often a leg. This can be the result of peripheral vascular disease, which occurs when there is a blockage in the arteries leading to or in the affected limb. Blockages can occur for many reasons, but smoking and poorly controlled diabetes are major factors. When a limb’s blood flow is blocked or reduced, there will be increased pain and reduced movement. The affected limb may also become pale and cold. Sores may develop and will not heal. If left untreated, the limb will gradually die and become a major risk for infection to the rest of the body while impacting the patient’s mobility.
