Raynaud's phenomenon is a vasospastic disorder of the small peripheral arteries called arterioles. This condition usually effects the fingers and toes but occasionally may effect other acral body parts such as the tongue, ear lobes, lips or nose. The term Raynaud's Phenomenon refers to the vasospastic process that occurs. Raynaud's Disease refers to the condition. Raynaud's disease is found primarily in women between the ages of 20 and 60 years of age.
The most common form of Raynaud's Disease is ideopathic primary Raynaud's Disease and is found in young women in 60-90% of the cases reported.(1) Primary Raynaud's Disease describes the condition without secondary contributing factors. Secondary Raynaud's Disease is due to other connective or soft tissue disorders such as rheumatoid arthritis, systemic lupus or scleroderma.(2) Occasionally, secondary Raynaud's Disease may be due to peripheral vascular occlusive disease, neurogenic lesions or drug intoxications.
The picture to the left shows an interesting case of Raynaud's Disease that effects only the weight bearing surface of the digits. This 73 y/o patient described a 3 year history of sores on the bottom of her toes that began during the winter months and ended in spring with the onset of warm weather. The patient was not active and sat for long periods of time with her feet flat on the floor. The ischemic changes seen in the skin are specific to the weight bearing portions of her toes. This was caused by a combination of arterial vasospasm (Raynaud's Disease) and direct pressure to the skin by the floor that inhibited normal blood flow to the plantar surface of the digit. Treatment for this problem included limitation of cold exposure and elevating the feet to eliminate floor pressure against the toes.
Causes and contributing factors
The cause of Primary Raynaud's Disease is unknown. Any condition or contributing factor that results in peripheral vasospasm may be considered a contributing cause of Secondary Raynaud's Phenomenon and Secondary Raynaud's Disease. Contributing conditions include anxiety, depression, rheumatoid arthritis, systemic lupus (SLE) and scleroderma. Contributing factors include cold exposure and nicotine. Primary and Secondary Raynaud's Disease is often seasonal and most active in the cold weather months. Exposure to cold air (air conditioning) during the summer can also initiate the onset of Raynaud's Phenomenon. Stress can also be considered a contributing factor to Raynaud's. Any emotional response that stimulates the sympathetic outflow or the release of catecholamines (stress, anger) may contribute to Raynaud's Disease.
The differential diagnosis for Raynaud's Disease includes;
Initial treatment of Raynaud's Disease consists of avoidance of any contributing factors to the condition such as cold exposure, emotional swings or smoking (including smokless tobacco and vape pens). Nicotine is a potent vasoconstrictor. Sedatives, mood stabilizers and psychological counseling may be helpful to control contributing factors such as stress and anxiety that may contribute to Secondary Raynaud's Disease.
Active Raynaud's phenomenon should be treated with slow warming. Rapid warming may result in reflux hyperemia and pain. Warming the hands and feet in luke warm water is recommended.
Drug therapies include two categories of medications;
Calcium channel blockers - calcium channel blockers are used to treat high blood pressure. The mechanism of action for this category of drug is to relax the peripheral resistance in arteries and smaller arterioles.(3,4,5) This mechanism of action tends to increase circulation to the extremities. Examples of calcium channel blockers include;
Alpha blockers, also used to treat high blood pressure, are used to decrease sympathetic tone of the arteries. Examples of this class of drugs includes;
A surgical procedure performed by a neurosurgeon, called a sympathectomy, is reserved for the most severe cases of Raynaud's Disease. A sympathectomy is a surgical release of the sympathetic nerve root at the area of the spine, treating the nerve that affects the extremity (arm or leg).
Drugs to avoid that may contribute to Raynaud's Disease include the following;
Topical L-arginine cream can help warm hands and toes. L-arginine cream is a good prophylactic trick to pre-empt cold exposure and is handy for going outdoors in cold climates in winter. In-shoe warming devices are also helpful in this regard.
Complementary and Alternative Therapies
Visual imagery techniques are helpful for some patients. As an example;
Wendy has had problems with Raynaud's Disease for years. She is a mom and employed as a banker. On days where she is particularly busy, her fingers will blanch white and become cold. Wendy has found that she can control these symptoms by stopping everything that she is doing. She folds her hands in her lap and visualizes in her mind a beam of sunlight coming through a window focused on her hands. She feels the warmth of the sun on her hands. Wendy performs this exercise as needed. In addition to improving the temperature of her hands, she also notices a reduction in her stress level and tightness in her back.
Nutritional supplements that may help to treat Raynaud's Disease include;
When to contact your doctor
If your Raynaud's becomes frequent and difficult to manage, consult your podiatrist or primary care doctor for additional treatment recommendations.
