In its initial stage, Obstructive Arteriopathy of Lower Limb (AOMI) has almost no symptoms.
The first sign of arteritis is when blood supply to the arteries begins to be insufficient, with stressful claudication: an intense calf-like pain during walking, which forces the patient to 'Stop. When they are under stress, the muscles need to get more blood and oxygen, which is not possible because of the narrowing of the arteries. It is therefore this lack of blood supply in the lower limbs that causes the pain.
The walking distance (PM: stopping distance of the walk) will be the indicator of the state of evolution of the disease. If the claudication is "wide" and is 500-700 meters, arteritis is moderate; it becomes "tight" from 50-100 meters, and indicates that the disease is at a much more advanced stage.
If the patient begins to have pain all the time, this means that the disease is at an ultimate stage of seriousness, where the patient is seriously at risk of ischemia. In this case, it will be necessary to intervene urgently: the surgery or an endovascular gesture represent the treatments of reference.
