Thromboembolic vasculitis occurs mainly in the medium and small arteries and veins of the extremities, most often in the lower limbs, and in male young adults. Thromboembolic vasculitis is a chronic, segmental, periodic attack of vascular inflammatory lesions. It mainly occurs in the middle and small arteries and veins of the limbs, i.e. the ends of the limbs. Clinical manifestations include pallor of the affected limbs, decreased skin temperature, soreness, numbness, tingling and burning sensation. As the disease progresses, resting pain, blackening of the toes and ulcers may occur. Individuals may need to consider amputation of the limbs or toes in severe cases, which may have a serious impact on their future lives, and therefore need to be actively treated as soon as the disease is detected.
