Ischemic gangrene of the lower extremity cannot be treated with too much reliance on stents and balloon dilation Among the types of diabetic foot, ischemic dry gangrene is the most difficult to treat, with long lead times, high costs, and high amputation rates. This is a “sticking point” and one of the reasons for it is that we rely too much on vascular interventions to treat it, ignoring the possibilities, effectiveness and advantages of other treatment options. Diabetic lower extremity arterial occlusion is mostly diffuse and multiple occlusion, not only large vessels, but also small vessels and microvessels can be occluded. For the vessels with large lumen can be surgically unblocked, but small vessels and microvessels cannot be done. This is like the tributaries of a large river blocking up, and the local wound still does not get sufficient blood supply, so it is difficult to serve the purpose of improving blood circulation. Moreover, it is a consensus in the industry that the risk of recurrence of intervention is relatively high, and it is also a fact that everyone wants to avoid. The need for another or even multiple surgeries after recurrence can be very harmful to the patient and can add to the financial burden. If surgery is not available, the result will be amputation. At the same time, for those patients who can undergo surgery again, the late stage is still not promising. There are many factors that affect interventional treatment overall. I strongly agree with Prof. Cao Yemin from Shanghai Hospital of Integrative Medicine that the timing of vascular interventions affects the outcome of treatment, and that doing it early or late does not work. However, it is not only the timing that matters, but also the indications and contraindications for interventional treatment, so some people can do it and some people cannot. What’s more, improving blood circulation is only one aspect of diabetic foot treatment; there are many other issues that need attention, such as the comprehensive treatment and management of local wound trauma. In this regard, the interventional treatment of wounds lacks effective treatment experience. After the patient has had interventional treatment in vascular surgery, he needs to be transferred to endocrine and other departments to treat the wound again, and the treatment in vascular surgery is basically finished, and the whole treatment does not have coherence, which makes it difficult for the wound to grow well, and the interventional treatment loses its meaning. In this conference, a number of young doctors also expressed their opinions. They started with Western medicine and stenting as well. When they came in contact with TCM and witnessed the therapeutic effect of TCM, they said that our current treatment plan is too dependent on interventional therapy, and patients do not necessarily need to have stenting, but the clinical recovery through conservative treatment with TCM will be better instead. Chinese medicine is of great significance to the trauma and the control of trauma infection. As for the current treatment of diabetic foot trauma and the control of infection, the two main aspects are improving circulation and trauma healing. In contrast, TCM treatment is more conservative and consists mainly of TCM treatment of peripheral vascular disease and TCM simmering of pus to create muscle. Compared with Western medicine, TCM has a clear theoretical basis for the treatment of peripheral vascular disease – TCM treats the “blood vessels”, “blood flow”, and the “irrigation” of blood. the body, and “blood stasis”, “blood clotting”, “pain is not passable” and “activating blood stasis “It is similar to Western medicine’s theories on blood vessel anatomy, physiology, blood hypercoagulation, blood vessel obstruction and antithrombotic therapy. TCM treats wounds with a combination of herbal water, herbal oil, ointment, osmosis, water, and injection, especially acupuncture point injection, which instills drugs directly into the lesion and can effectively improve circulation, establish collateral circulation, improve microcirculation, increase local blood oxygen saturation, and provide the necessary conditions to promote wound healing. On the other hand, simmering pus and generating muscle to treat wounds is another advantage of TCM treatment. Using the method of simmering pus and generating muscle, for wounds after debridement, dialectical treatment is applied to the sore surface with different kinds of Chinese herbal ointment (powder) to increase the exudation of pus from the wound and carry the evil out, which can improve the resistance, immunity and proliferation ability of the local wound, effectively and quickly control the wound infection and promote the natural growth of healthy muscle tissue and skin and other tissues on the wound surface. In the process of TCM treatment, there is no need for skin grafting, no intervention, no negative pressure, and it also avoids the use of a lot of antibiotics and causes little damage to the patient. Case after case has confirmed that diabetic foot ischemic gangrene recovery through conservative treatment with Chinese and Western medicine is very effective, with a high rate of limb preservation, only the cycle will be relatively long. But if the disease can be cured and the patient can avoid amputation, nothing else will be a problem. Of course, although the effect of combining Chinese and Western medicine deserves recognition, there are different voices and opinions. This is hard to avoid, and I also think it is a prerequisite for medicine to progress. For us combined Chinese and Western medicine doctors, we must be tolerant and more confident to keep learning new knowledge and new ideas to help more diabetic foot patients not to amputate their limbs.
