The theme proposed by the International Diabetes Federation this year is diabetic foot (DF), so why this importance? It has been half a century since DF was introduced in medical history, but in recent years, with the dramatic increase in the incidence of diabetes, the prevalence of DF has also increased. According to statistics from many countries, DF accounts for 2-15% of the total number of people with diabetes, of which 10-24% eventually require surgical amputation. This not only brings huge medical costs, but also deals a heavy blow to the physical and mental health of patients. For this reason, WHO has not only listed DF as one of the four major complications of diabetes, but also called for a 50% reduction in the amputation rate of DF in the St. Vincent’s Declaration. In order to make the treatment of DF reach the advanced level at home and abroad, we have formed a research group together with senior diabetic experts, using our strong points to measure the pulse pressure index and vascular flow velocity of diseased vessels according to angiography and Doppler ultrasound imaging, and use one or more of the following vascular recanalization procedures on a case-by-case basis, with the narrowed There are minimally invasive balloon dilatation or stenting of the stenosed vessels; there are bypasses of the occluded segment with autologous veins or artificial vessels; there are also “arterialization” of the venous vessels to reconstruct the arterial blood supply; there are also different systemic and local “drug meals” that are selected according to the laboratory condition to open up the collateral circulation and open up the arterial blood supply. According to the laboratory condition, different systemic and local “drug meals” are used to open the side branch circulation and build “pulling bridges”. According to the scope and degree of vascular lesions, the road is paved and bridges are built. We call it “road and bridge” and “combination bridge” therapy of DF, which has achieved promising results. More importantly, the success or failure of the above therapies requires a heart first. Because most of DF have anaerobic bacteria and aerobic bacteria mixed infection, rotting flesh stink, surgery and very detailed and complicated, if the doctor lack of love, contrary to medical ethics, amputation, this negative and simple treatment will give the patient’s mental shock and life self-care infinite harm. Therefore, our requirement is that as long as the affected limb (toe) has one percent hope of survival, we should make 100% effort, not minding its odor, not being tired of it, not being afraid of its difficulties, to return the patient a sound foot.
