Critical limb ischemia requires prompt treatment. Restoring proper blood flow to your hands and feet can help reduce the chances that you’ll need an amputation. Your healthcare provider may recommend:

  • Medications to prevent clots, reduce blood pressure and lower cholesterol.
  • Endovascular treatments (minimally invasive), such as angioplasty (placing a stent) to open blocked arteries or atherectomy to remove plaque buildup.
  • Surgery to repair or replace an artery either using one of your own veins or a synthetic replacement.

If none of these treatments adequately restore blood flow, your healthcare provider may need to remove part of your finger, hand, toe, foot or leg. About 1 in 5 people with critical limb ischemia eventually need an amputation. People with diabetes are much more likely to need an amputation.
