Liang Bo, 82 years old, had frequent pain and numbness in his lower left leg in the past six months, and he didn’t pay much attention to it at first, but the pain in the lower limb became more and more serious, and the lower limb also had blackness, ulceration and cold skin. Liang Bo went to the Cardiothoracic Vascular Surgery Department of Kaifeng Central Hospital for medical examination and was diagnosed with lower limb atherosclerosis occlusive disease. He then realized that if not treated in time, he would face amputation or even life threatening. Meng Qingjiang, deputy chief physician of the department, personally performed the “balloon dilation + stent revascularization” surgery for him. After the surgery, Liang’s pain was significantly relieved, the skin color and temperature of the lower limb returned to normal, and the ulcerated surface healed quickly. Meng Qingjiang, deputy chief physician of cardiothoracic vascular surgery in downtown hospital, master of medicine, member of provincial thoracic surgery society, member and secretary of municipal thoracic and cardiac surgery society. He has rich clinical experience, specializing in the comprehensive treatment of large blood vessels and peripheral vascular diseases, as well as the surgical treatment of coronary heart disease, wind heart disease, precordial disease and chest tumors, and is highly respected by patients. Meng Qingjiang told reporters that the elderly usually have back and leg pain and other problems, but it should be reminded that leg pain is not necessarily a minor problem, there may be a lower limb arteriosclerosis occlusive disease. This disease, if not treated in time, may be due to lower limb ischemic necrosis and amputation, combined with diabetes, hypertension, cardiovascular and cerebrovascular disease patients, mortality rate of up to 40% within two years. Meng Qingjiang pointed out that atherosclerosis occlusive disease is a local manifestation of atherosclerosis in the limbs, mostly in the lower limbs. The survey shows that the incidence of this disease is increasing, especially in men over 45 years old. Its symptoms are similar to those of low back and leg pain caused by arthritis and lumbar disc herniation and compression, so it is easily misdiagnosed as general geriatric pain. Most patients suffer from ischemic necrosis of the lower extremities, which seriously affects the quality of work and life, and it is extremely difficult to heal after skin ulceration, easily causing intractable infections and even sepsis, and many patients need to have their limbs amputated to save their lives. The traditional treatment of the disease is based on antiplatelet and vasodilator drugs, but the effect is not very satisfactory. The choice of surgical treatment is very traumatic and risky, which is difficult to endure for elderly patients like Liang Bo. Meng Qingjiang told reporters that the “balloon dilation + stent revascularization” surgery is the ideal choice for the treatment of the disease. The procedure only requires a half-meter opening at the root of the thigh, a minimally invasive device such as a guidewire is sent to the diseased artery, and then the diseased artery is balloon dilated and a stent is placed to open the narrowed and occluded vessel. This kind of endoluminal intervention is increasingly chosen by more and more people because of its advantages of being less invasive and repeatable.
