Acute limb ischemia is a rapid decrease in the blood flow to an upper or lower limb due to a sudden block in the blood vessel, usually due to a clot. Clot could form either locally or get carried to the site from a clot elsewhere like the chambers of the heart. Sudden loss of blood supply causes severe pain, pallor of the limb, coldness of the limb, loss of sensation and loss of muscle power. Prompt treatment is required to save the limb as well as life.
