Study Notes
- Raynaud's is a rare vascular disorder.
- It causes vasospasming of arteries in fingers and/or toes.
- This decreases blood flow to the extremities.
Primary Raynaud's (Raynaud's Disease)
- The cause is idiopathic (unknown).
- It is the more common type of Raynaud's.
- Symptoms tend to be less severe than secondary Raynaud's.
Secondary Raynaud's (Raynaud's Phenomenon)
- It is associated with an underlying connective tissue disease.
- Lupus or scleroderma can damage the arteries.
Signs and Symptoms
- Upon exposure to cold or stress, fingers become cyanotic, cold, painful, and numb.
- After spasming, blood flow returns, causing fingers to turn red.
Diagnosis
- Diagnosis is usually based on clinical signs and symptoms.
- An ANA titer (anti-nuclear antibody titer) can assess for underlying autoimmune disorders.
Treatment
- Vasodilators are used in treatment.
- A sympathectomy can be done for severe cases.
Patient Teaching
- Avoid cold exposure and dress warmly.
- Decrease caffeine intake because it causes vasoconstriction.
- Reduce stress levels.
- Stop smoking.
