Peripheral Arterial Disease (PAD) can range from mild leg discomfort to life-threatening complications. The most severe stage is called Critical Limb Ischemia (CLI). This advanced form of PAD occurs when blood flow to the legs is so restricted that tissues begin to die. Without urgent treatment, CLI often leads to amputation. Recognizing this condition early can save both limbs and lives.
What is CLI?
CLI is a severe obstruction of blood flow in the arteries of the legs, usually the result of untreated PAD. Unlike claudication (pain only when walking), CLI causes pain at rest, slow-healing wounds, and in severe cases, gangrene.
Symptoms of CLI
- Severe pain in the feet or toes, even at rest
- Non-healing sores or ulcers on the feet and legs
- Black or dead tissue (gangrene)
- Skin that is shiny, cool, or pale
- Loss of sensation in the feet
Risk Factors for CLI
- Longstanding PAD
- Diabetes
- Kidney disease
- Smoking
- High cholesterol and hypertension
Why CLI is Dangerous
CLI is associated with a high risk of amputation and is linked to increased mortality due to heart attack and stroke. Studies show that without treatment, up to 40% of CLI patients may require major amputation within six months.

Frequently Asked Questions (FAQ)
Q: Is CLI the same as gangrene?
A: Gangrene is a complication of CLI, but CLI can exist without it.
Q: Can CLI be reversed?
A: With prompt treatment, blood flow can often be restored, saving the limb.
Q: What happens if CLI is left untreated?
A: CLI often leads to severe infection, gangrene, and amputation.
Q: How quickly should I seek help if I suspect CLI?
A: Immediately. CLI is a vascular emergency.
