What is Critical limb ischemia

Critical limb ischemia (CLI) is a severe form of peripheral arterial disease (PAD) that occurs when there is a significant blockage in the arteries supplying blood to the legs and feet. This condition is characterized by a chronic lack of blood flow to the affected limb, leading to severe pain, non-healing wounds, and tissue damage. CLI typically affects individuals with underlying conditions such as diabetes, smoking, high blood pressure, or high cholesterol.

Early diagnosis and treatment of CLI are crucial to prevent complications like gangrene and amputation. Treatment options may include lifestyle modifications, medication to manage risk factors, and revascularization procedures to restore blood flow. Revascularization techniques can involve angioplasty, stenting, or bypass surgery, depending on the severity and location of the blockage.

It is important for individuals at risk or experiencing symptoms such as leg pain, ulcers, or non-healing wounds to seek medical attention promptly. CLI requires a multidisciplinary approach involving vascular specialists, wound care experts, and other healthcare professionals to provide comprehensive care and improve outcomes for patients.
