Raynaud's phenomenon

[ra-nōz´]

intermittent bilateral attacks of ischemia of the fingers or toes and sometimes the ears or nose, marked by severe pallor, and often accompanied by paresthesia and pain; it is brought on characteristically by cold or emotional stimuli and relieved by heat, and is due to an underlying disease or anatomical abnormality. When the condition is idiopathic or primary it is termed raynaud's disease.

Narrowing of the arteries and arterioles of the fingers and toes, often triggered by cold or stress, resulting in blanching, cyanosis, numbness, pain, and, in extreme cases, gangrene.

Raynaud's phenomenon

The term given to the symptoms of RAYNAUD'S DISEASE when the cause is known. Raynaud's phenomenon may be caused by any form of narrowing arterial disease, such as ATHEROSCLEROSIS, Buerger's disease (THROMBOANGIITIS OBLITERANS), EMBOLISM, THROMBOSIS, diabetic large vessel disease, RHEUMATOID ARTHRITIS or SYSTEMIC LUPUS ERYTHEMATOSUS. It may also be caused by repetitive strain or strong vibration or artery-constricting drugs or poisons. The treatment is the management of the cause.
