Hemiplegia, also known as Raynaud’s syndrome, is a group of syndromes in which episodes of pale, purplish fingers, followed by flushing, are caused by cold or emotional stress. If there is no specific cause, it is called idiopathic Raynaud’s syndrome. If it is secondary to another condition, it is called secondary Raynaud’s syndrome. Its main causes are cold irritation, nervous excitement, occupational factors, prolonged engagement in vibratory mechanical work, endocrine disorders, and other causes. Secondary Raynaud’s disease is mostly seen in systemic lupus erythematosus, rheumatoid arthritis, systemic scleroderma, as well as thrombophlebitis, primary pulmonary hypertension and so on. Clinical manifestations are mainly in the beginning of winter attacks, short time, cold hands and feet, numbness, and pain. The general treatment for this condition is to avoid exposure to cold. Calcium antagonists can also be given. If medications are not effective, sympathectomy may be considered.
