Stage 3 of peripheral arterial occlusion (PAO) is the most severe form of the condition. It is also referred to as critical limb ischemia (CLI). This stage is characterized by a severely narrowed artery, resulting in a lack of oxygen-rich blood reaching the muscles and tissues in the affected limb. Symptoms of stage 3 PAO include severe pain, numbness, and discoloration in the affected limb.
Risk Factors for Stage 3 PAO
The risk factors for developing stage 3 PAO are the same as those for the earlier stages of the condition. These include age, smoking, diabetes, obesity, high cholesterol, and a sedentary lifestyle.
Treatment for Stage 3 PAO
Treatment for stage 3 PAO will depend on the severity of the condition. Non-surgical treatments such as lifestyle changes, medications, and physical therapy may be used to improve blood flow to the affected limb. In some cases, surgery may be necessary to open up the blocked artery. Surgery may include angioplasty, stenting, and bypass surgery.
