Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. [1] Typically the fingers, and, less commonly, the toes, are involved. [ 1 ]
Raynaud’s disease is a rare peripheral vascular syndrome that narrows blood vessels, generally in the hands and feet, due to cold or stressful emotion. [8] It is recognized by the reduction of blood flow to fingers and toes with periodic spasm and results in a drastic color change to white or blue.
In people with Raynaud’s phenomenon, cold temperatures or stress trigger spasms in the small blood vessels near the surface of the skin, causing the vessels to constrict and limit blood flow.
Raynaud's phenomenon is frequently the first manifestation of CREST/lcSSc, preceding other symptoms by years. Stress and cold temperature induce an exaggerated vasoconstriction of the small arteries, arterioles, and thermoregulatory vessels of the skin of the digits. Clinically this manifests as a white-blue-red transition in skin color.
HAVS is a widespread recognized industrial disease affecting tens of thousands of workers. It is a disorder that affects the blood vessels, nerves, muscles, and joints of the hand, wrist, and arm. Its best known effect is vibration-induced white finger (VWF), a term introduced by the Industrial Injury Advisory Council in 1970.
Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes become severe, and fatal. [3] Coronary heart disease for example, is the leading cause of death for men and women in the United States. [5]
Chronic vasoconstriction is associated with hypertension, a major risk factor for cardiovascular diseases such as heart attack and stroke. Moreover, impaired blood flow resulting from abnormal vasoconstriction may contribute to tissue ischemia, which can be observed in conditions like Raynaud's disease.
Other uncommon causes are coarctation of the aorta, [4] Trousseau disease [medical citation needed] and Buerger's disease (thromboangiitis obliterans), [5] in which vasculitis occurs. Raynaud's phenomenon functional vasospasm. [clarification needed] It is distinct from neurogenic claudication, which is associated with lumbar spinal stenosis. It ...
