Critical limb ischemia (CLI) is a chronic condition in which there is severe blockage in the arteries that supply blood to the lower extremities. The condition develops starting with atherosclerosis which is the narrowing and hardening of the arteries before advancing to peripheral arterial disease in which the buildup of plaque occurs over time. Critical limb ischemia is the more severe form of PAD.
People with CLI experience severe pain in the feet and/or toes. Unlike milder forms of PAD, the pain associated with CLI can be felt even when at rest. This pain is referred to as “Ischemic Rest Pain” and it is sometimes accompanied by sores on the lower extremities that won’t heal.
At Bergen Surgical Specialists, we encourage patients to have their condition evaluated at one of the top vascular centers in Bergen County. Early diagnosis is important towards preventing advancement of atherosclerosis to CLI. In addition to the pain and sores associated with the condition, other possible conditions include:
- Dry skin that appears shiny and smooth on the legs or feet
- Lacking or diminished pulse in the lower extremities
- Thickening of toenails
- Dry, black skin on the feet or legs (gangrene)
There are a number of factors that put some people at a greater risk of developing atherosclerosis and CLI including age, overweight, diabetes, smoking, leading a sedentary lifestyle, and a family history of either atherosclerosis or CLI. The vascular doctor in Bergen County will consider these and other factors when evaluating your condition and advising you on the best course of action for your future vascular health.
