With the improvement of people’s standard of living, the increase of mobility tools, the decrease of exercise, the increase of social pressure and work pace, the change of social aging, type 2 diabetes, which used to be the “rich disease” more and more, early some patients often do not think. In fact, diabetes has many complications, especially damage to the body’s blood vessels. A significant number of vascular diseases are related to diabetes: diabetic foot in the lower extremities, renal artery stenosis, carotid plaque and other multi-site peripheral arterial lesions. Among them, diabetic foot can lead to ischemia, pain, ulceration, gangrene, and even amputation of the distal lower extremities. Renal artery stenosis can cause intractable hypertension, and in the middle and distal stages can cause kidney atrophy and even renal failure! Therefore, we must pay attention to early diagnosis and treatment, and seize the best time for medical treatment! The update of drugs, especially the rise and development of “minimally invasive treatment” in vascular surgery, have provided a powerful weapon for clinical treatment!
