We often hear that bypass surgery for the heart, which is the international vascular surgery method with the highest patency rate, has been used for decades for atherosclerotic occlusive disease, and in recent years it has been found to have very good limb-preserving effects for diabetic foot. Many diabetics with diseased feet have avoided amputation after having a “bypass”. Recently, a 60-year-old glucose patient, Dr. Zhang Xiansheng, chief of vascular surgery, used lower limb artery artificial vessel bypass to open up the blood supply to his left lower limb. Including this patient, the department has preserved the limbs of more than 5,000 diabetic foot patients. The chief surgeon, Dr. Xiangsheng Zhang, chief of vascular surgery, found after consultation that this patient’s diseased foot had experienced what started as a soybean-sized opening and slowly evolved into almost a color change in the entire lower leg. Although diabetic foot vascular surgery can save some patients’ legs, many patients can actually contain the infection of the wound sooner. From the size of a soybean grain to the entire calf, the process in between can be controlled if one goes to the hospital early. There are now about 100 million people with diabetes in China, and the incidence of diabetic foot is increasing with the age of the disease. Several studies have also confirmed that half of the annual amputations are diabetic foot. If prevention is done and wounds are treated early, 80% of amputations can be avoided. The fear is not to take a small wound seriously, until you find a serious wound before seeking medical advice. The dorsalis pedis artery and the posterior tibial artery are superficially located, so as long as the location of these two arteries is identified, it is possible to find out whether the vessels are open by palpation. the blood vessel to be reopened.
