Description

Technical Field

[0002] The basic pathological change of atherosclerosis is the formation of plaques on the inner surface of the artery, including lipid streaks, fibrous plaques and atherosclerotic plaques. If the lesions continue to worsen, secondary lesions such as calcification, atherosclerotic ulcer formation, thrombosis and intraplaque hemorrhage may occur. Atherosclerosis of the lower limb arteries is mainly caused by atherosclerotic plaques in the leg arteries, which become narrow. In severe cases, it can lead to ischemic necrosis of the lower limbs. Clinically, symptoms such as numbness, weakness, and pain in the legs will appear, and symptoms such as hair loss in the legs and feet may also occur. Medical staff generally choose complex surgery to treat the lower limb arteries, that is, open surgery and interventional surgery combined with femoral artery incision and endarterectomy.
