Arterial occlusive disease of lower extremity

Arteriosclerotic occlusive disease is a degenerative disease. It is the basic pathological process of large and middle arteries. It is mainly the abnormal deposition of cells, fibrous matrix, lipids and tissue fragments. Variety. In peripheral vascular disorders, arterial stenosis, occlusive or aneurysmal lesions are almost always caused by arteriosclerosis. Arteriosclerotic lesions are generally systemic diseases, which occur in some large and medium-sized arteries, such as the lower abdominal aorta, iliac arteries, femoral arteries, and iliac arteries. The arteries of the upper limbs are rarely involved. The diseased arteries thickened and hardened, accompanied by atheromatous plaque and calcification, and secondary to thrombosis, resulting in narrowing or occlusion of the arterial lumen and ischemic limbs. The affected limb has clinical manifestations such as chills, numbness, pain, intermittent claudication, and ulcers or necrosis of the toes or feet. Sometimes narrow or occlusive lesions are segmental and multi-planar. They occur in the origin of the bifurcation of the artery and the posterior wall of the lumen, and the curvature of the arterial trunk is often involved. There is often a smooth outflow tract on the far side presence.
