Atherosclerosis is one of the most common diseases among the elderly, with an incidence rate as high as 79.9% in people over 60 years old in our country. Atherosclerotic diseases mainly refer to arteriosclerotic occlusive disease, followed by diabetic arterial occlusive disease. In peripheral vessels, the continuous expansion of atherosclerotic substances and secondary thrombosis can cause arterial lumen stenosis or occlusion, leading to chronic or acute bleeding symptoms in the limbs. This disease is called arteriosclerosis obliterans (ASO). Arteriosclerosis obliterans often occurs in the lower end of the abdominal aorta, iliac artery, or femoral-popliteal artery. In Western countries, the incidence of arteriosclerosis obliterans is relatively high; in the United States, the incidence rate is 10% in people over 70 years old and 1-2% in those aged 37-69 years. Currently, about 100,000 people receive treatment each year. In our country, with the improvement in living standards, changes in dietary structure, population aging, and the widespread application of non-invasive vascular examination technologies, ASO has now become a common peripheral vascular occlusive disease among middle-aged and elderly people.
This disease mostly occurs in people over 50 years old.
