Alerts and Notices
SynopsisRaynaud phenomenon is a vascular disorder characterized by intermittent arteriolar vasospasm of the digits, most often due to cold temperature or stress. Symptoms present with characteristic changing of hands from white (pallor) to blue (cyanosis) to red (hyperemia), although all 3 phases may not be present in each individual. Raynaud phenomenon may be primary or secondary.
Primary Raynaud phenomenon typically follows a less severe course than secondary Raynaud phenomenon. In primary Raynaud phenomenon, also termed Raynaud disease, vasospasm is not associated with ischemic injury or an underlying associated disease. Primary Raynaud phenomenon typically presents at a younger age (< 30 years), involves all fingers symmetrically excluding the thumbs, and is not painful. Patients do not have a history of peripheral vascular disease or ischemic injury. Antinuclear antibody titers are normal or low (< 1:40 on indirect immunofluorescence) and nail fold capillaries are normal.
Secondary Raynaud phenomenon is associated with an underlying disease, usually a connective tissue disease of which systemic sclerosis is the most common. Because vasospasm is associated with concurrent ischemia, attacks are typically painful and asymmetric involvement of digits or hands is common. Digital ulcerations or necrosis, digital tuft pits, pterygium inversum, and tortuous nail fold capillaries with capillary dropout may be seen.
Additional associations include systemic lupus erythematosus, rheumatoid arthritis, pulmonary hypertension, frostbite, hematologic malignancies, polyvinyl chloride exposure, cryoglobulinemia, reflex sympathetic dystrophy, repeated trauma / vibration, arteriovenous fistula, intra-arterial drug administration, thoracic outlet syndrome, thromboangiitis obliterans, and Takayasu arteritis.

Differential Diagnosis & PitfallsStructural vasculopathies:
- Thoracic outlet syndrome
- Brachiocephalic trunk disease (atherosclerosis, Takayasu arteritis)
- Buerger disease (thromboangiitis obliterans)
- Crutch pressure
- Systemic sclerosis
- Systemic lupus erythematosus
- Connective tissue overlap syndromes
- Cold injury
- Vibration disease (hand-arm vibration syndrome, hypothenar hammer syndrome)
- Chemotherapy (bleomycin, vinca alkaloids, cisplatin, carboplatin)
- Vinyl chloride disease
- Arsenic poisoning
- Cryoglobulinemia (monoclonal or mixed)
- Cold agglutinin disease
- Myeloproliferative disorders
- Drug-induced Raynaud (ergot alkaloids, bromocriptine, interferon, estrogen, cyclosporine, sympathomimetic agents, clonidine, cocaine, nicotine)
- Carpal tunnel syndrome
- Carcinoid syndrome
- Reflex sympathetic dystrophy
- Pernio – itching, burning, or painful lesions on the extremities after exposure to nonfreezing cold; lesions last for 1-3 weeks
- Erythromelalgia – burning, pain, and warmth of extremities worsened by heat and improved by cold
- Cold hypersensitivity – no skin color changes
- Achenbach syndrome – paroxysmal bruising in the hand or fingers, of unknown etiology
- Atrial myxoma

Patient Information for Raynaud phenomenon in Adult
OverviewRaynaud's phenomenon is a disorder in which the blood vessels to the fingers and toes (digits) become abnormally closed off (constricted). The fingers and toes of individuals with Raynaud's phenomenon change color from white to blue to red, often causing them to feel numb. Raynaud's phenomenon is sometimes seen with autoimmune diseases, such as rheumatoid arthritis, scleroderma, and lupus, where the body's immune system turns against itself, causing various symptoms. Other causes of Raynaud's phenomenon include repeated trauma/vibration, abnormalities in the structure of blood vessels, and drug injection into one type of blood vessel (arteries).
Who’s At RiskRaynaud's phenomenon usually affects younger to middle-aged women. When it affects men, it is usually seen in middle age or later in life. Raynaud's phenomenon is seen in 20% of people with lupus.
Signs & Symptoms
- Raynaud's phenomenon affects the fingers and toes (digits). The digits feel cool and their color changes from white to blue to red.
- Severe Raynaud's phenomenon can result in skin ulcers. This complication is more common in people who have both scleroderma and Raynaud's phenomenon.
- People with Raynaud's phenomenon may have more noticeable small blood vessels (capillaries) into their fingers and toes where the nail plate meets the skin of the finger (proximal nail fold), particularly in people who also have an autoimmune disease.
Self-Care GuidelinesAvoid exposure to cold as much as possible, and do not smoke, as this contributes to blood vessel narrowing.
When to Seek Medical CareSee your doctor if you notice symptoms suspicious for Raynaud's phenomenon. Further testing may be needed to see if you might have another medical condition that is causing your symptoms.
- Oral medications, including nifedipine (a blood pressure medication), epoprostenol (a prostaglandin), or a drug that affects the nerves (selective serotonin reuptake inhibitor), such as fluoxetine.
- Topical nitroglycerin paste, which helps to dilate blood vessels, may be used as needed to treat or prevent active Raynaud's phenomenon. Apply the paste carefully as it can lead to low blood pressure (hypotension) if used on large areas.
- Biofeedback, which is a treatment technique in which people are trained to improve their health by using signals from their own bodies, is another therapy for Raynaud's phenomenon.
