Diagnosis may involve ABI testing, vascular ultrasound, CT angiography, circulation studies, and vascular examination.

Healing depends on restoring adequate blood flow. Early vascular treatment significantly improves wound-healing potential.

Patients with diabetes, smoking history, peripheral artery disease, high blood pressure, or chronic kidney disease are at highest risk.

Yes. Without treatment, CLI can lead to infection, tissue loss, gangrene, or amputation.

Symptoms may include foot pain at rest, cold feet, slow-healing wounds, numbness, and skin discoloration.

Poor circulation is commonly caused by plaque buildup inside arteries, smoking, diabetes, high blood pressure, and vascular disease.

Critical Limb Ischemia (CLI) is a severe form of peripheral artery disease caused by critically reduced blood flow to the legs or feet.

Treatment options may include angioplasty, stenting, bypass surgery, circulation restoration procedures, and wound-management care.
