Critical Limb Ischemia: A Severe Form of PAD and Its Management
Peripheral Artery Disease (PAD) happens when arteries in the legs become narrowed or blocked by plaque buildup. When PAD becomes very advanced, it can lead to Critical Limb Ischemia (CLI), a serious condition where blood flow is so limited that tissues in the legs and feet don’t get enough oxygen.
People with CLI may notice constant leg pain, especially at night, or wounds and sores on the toes or feet that don’t heal. The skin may become pale, shiny, or even dark in areas with poor blood flow. Without treatment, the lack of circulation can cause infections and tissue damage, sometimes leading to amputation.
Treatment focuses on restoring blood flow and preventing further complications. Options include medications, minimally invasive procedures like angioplasty or stent placement, or in some cases, bypass surgery to redirect blood around the blockage. Lifestyle changes such as quitting smoking, controlling diabetes, and maintaining healthy cholesterol levels are also vital parts of managing the condition.
At Pinnacle Vein and Vascular Center, our specialists use advanced imaging and treatment techniques to help restore circulation, relieve pain, and protect limb health for patients with severe PAD and CLI.
