? Thrombo-occlusive vasculitis, also known as Burgers disease, is a group of intractable arterial diseases with geographical characteristics that occur in the higher latitudes of East Asia. The common risk factors are smoking and cold, and the common age of onset is young people, especially men between 20-40 years old. As this disease occurs with ischemic necrosis of the toes and severe pain, commonly known as ten-finger pain, it severely affects the workforce of young adults in northern China. In China, because of the unclear understanding of thrombo-occlusive vasculitis, even doctors can not distinguish the difference between this disease and other arterial lesions, so the various regions, cities and counties have given birth to numerous vasculitis hospitals, using various methods to treat “vasculitis”, but in fact? Some of these “vasculitis” are old age arteriosclerosis, some are arterial embolism, some are diabetic foot, and some are true thrombo-occlusive vasculitis. Different vascular lesions, treatment methods vary too much, the elderly arteriosclerosis need to do stents or balloon expansion, or even bypass, arterial embolism need to remove the embolism, diabetic foot need to open the blood vessels. For true thrombo-occlusive vasculitis, none of these methods will make the patient pay higher medical costs without solving the problem at all, or even aggravating the condition. We have treated many cases in the local “vasculitis” hospital treatment, spending tens of thousands of dollars after the ineffective patients. In the field of vascular surgery, vasculitis is indeed no particularly effective surgical treatment of the disease, and drug conservative treatment, including infusions and oral medications, the effect is very limited, which is an important reason why large hospitals are reluctant to admit vasculitis. We tried to treat vasculitis 5 years ago with an intra-arterial minimally invasive retention program and injected free radical scavenging drugs to achieve effective results, and now we have improved the retention program and upgraded the drug injection program, allowing patients to be hospitalized for just a few days to improve their symptoms, and life actions are not affected at all during the period of retention and drug injection. A 32-year-old guy from Inner Mongolia, who prefers to smoke, has suffered from vasculitis for 2 years, does not walk more than 200 meters, and has pain when walking. The situation at the time of the outpatient visit: gangrene of the big toe, severe pain in the dark red ischemic area around the necrotic tissue, sleepless nights, and 20 pounds of weight loss. （Three months after the injection, the boy had no pain in the toe, the necrotic area had converged, the blood and oxygen supply to the surrounding ischemic tissues had improved significantly, the color was red and the line of demarcation with the necrotic area was clearly visible, he had no pain when walking for several kilometers, he slept well at night, his appetite had increased and his weight had recovered. (See the picture below.) Four months after the drug injection, the necrotic area further converged and crusted over, and already started to separate from the surrounding healthy tissues automatically, the healthy tissues had good blood supply and red color, the final result was that the necrotic tissues fell off and the healthy tissues closed, the treatment effect was very obvious.
