A few days ago, Dr. Yin Ruisheng, Director of the Department of Surgery, successfully performed bilateral femoral artery bypass grafting of the abdominal aorta for Mr. Tian, a 59-year-old patient, relieving the patient’s pain. Dr. Ruisheng Yin has been engaged in vascular surgery for many years and has accumulated rich clinical experience in treating patients with atherosclerotic occlusive disease, acute arterial embolism, Bugart’s syndrome, aneurysm, deep venous insufficiency of the lower extremity, venous thrombosis of the lower extremity, aortitis, etc. Mr. Tian was suffering from intermittent claudication, and had been in pain for a long time. Mr. Tian was admitted to the hospital with intermittent claudication, rest pain in both lower limbs for 3 months, and inability to walk for 20 days. DSA examination showed distal abdominal aortic occlusion, and bilateral occlusion of common iliac artery and internal and external iliac arteries. After surgical treatment, the old man recovered well and all original symptoms disappeared. Atherosclerosis is a common disease in middle-aged and old people, and the incidence is increasing. Atherosclerotic plaque and thrombus cause arterial stenosis and occlusion. According to the survey, the incidence rate of atherosclerosis is as high as 80% in the elderly over 60 years old. Early typical performance for intermittent claudication, lesions further development appears ischemic rest pain. As a result of the slow progression of atherosclerosis in elderly patients, the lesions are more extensive and often combined with chronic neurological changes, such as numbness or dullness of sensation in the limbs. If proper treatment or protection is not provided during this period, ischemic ulcers or gangrene will soon appear on the limbs. Elderly people are reminded to be highly vigilant and to seek prompt medical attention if they have similar symptoms.
