Vasculitis (also known as thrombo-occlusive vasculitis Buerger’s disease) is a chronic peripheral good and bad vascular occlusive very long inflammation, drugs mainly involving the extremities in small arteries and veins lower extremities, the more common manifestations of limb ischemia severe pain intermittent claudication foot, dorsal artery pulsation weakened or disappeared, wandering superficial arteritis severe cases can have ulceration or necrosis of the extremities. Vasculitis occurs in young men with a history of smoking, the cause is still unknown, statistics show that the incidence of vasculitis in cold areas is higher than in warm areas instead, the incidence of smoking population is higher than non-smokers, so most scholars believe that the onset of the disease is related to long-term smoking and cold and others believe that it is related to immunogenetic factors. The diagnosis of occlusive thrombophlebitis is based on the following points: (1) young male onset; (2) intermittent claudication of one or both lower limbs; (3) reduced or absent dorsal foot or posterior tibial artery pulsation; (4) with superficial wandering thrombophlebitis without hypertension hyperlipidemia diabetes and atherosclerosis; (5) limb position test spend elimination patients lying down elevate the lower limbs 45 °, 3 minutes later observe the foot Skin color change, this disease happy patients affected limb foot especially baby is toe skin showing pale or waxy yellow, acupressure then ischemia is more going on obvious numbness pain; asked the patient to sit up the lower limb natural drooping skin color recovery recommended slow or cyanotic. Smoking is an important perceptual trigger for this disease, so the treatment does not know on the special need should first quit smoking need to use vasodilators or sympathectomy techniques without the guidance of the director of the doctor serious need to act pulse diversion, and interventional surgery.
