“Atherosclerotic occlusive disease is a localized manifestation of atherosclerosis in the limbs, preferably in the lower limbs. Due to changes in modern dietary habits and the aging of the population, the incidence of this disease is increasing, especially in men over 45 years of age. Its symptoms are similar to arthritis, lumbar disc herniation compression and other causes of back and leg pain, so it is easy to be treated as a general geriatric pain and ignored, so that the development of lower limbs ischemic necrosis before attention is paid. Because ischemic necrosis of the lower limbs after most patients suffering, seriously affecting the work and quality of life, and skin ulceration is extremely difficult to heal, easy to cause refractory infections, and even lead to sepsis, many patients need to amputate in order to save their lives. “The traditional treatment of lower limb atherosclerosis occlusive disease is based on anti-platelet and vasodilator medication, but the effect is not very satisfactory; and the choice of surgical treatment is traumatic, high-risk, and is difficult to tolerate for patients of advanced age. What to do? The implementation of “balloon dilatation + stenting vascular recanalization” surgery, only need to open a half-meter-large hole in the thigh root, the guide wire and other minimally invasive instruments to the diseased artery, and then the diseased artery balloon dilatation, stenting, can be opened through the stenosis of the blocked blood vessels. This type of endovascular intervention is increasingly being chosen by more and more people because it is less invasive and can be repeated.
