Detailed explanation-1: -What is critical limb ischemia? Critical limb ischemia (CLI) is a severe blockage in the arteries of the lower extremities, which markedly reduces blood-flow. It is a serious form of peripheral arterial disease, or PAD, but less common than claudication.
Detailed explanation-2: -Claudication is pain in the legs or arms that occurs while walking or using the arms. The pain is caused by too little blood flow to the legs or arms. Claudication is usually a symptom of peripheral artery disease, in which the arteries that supply blood to the arms or legs, usually the legs, are narrowed.
Detailed explanation-3: -Acute limb ischemia (ALI) is a vascular emergency associated with a high risk for limb loss and death. Most cases result from in situ thrombosis in patients with preexisting peripheral arterial disease or those who have undergone vascular procedures including stenting and bypass grafts.
