Definition and causes

Raynaud's syndrome covers conditions that give anemia in the fingers and possibly. in feet (digital ischemia).

The distinction between primary Raynaud (Raynaud's disease), where the cause is unknown, and secondary Raynaud (Raynaud phenomenon), where the state acts in connection with another illness.

By pronounced cold, the small arteries (arterioles) in the fingers go into spasm spasticity. This leads to a deficient blood supply to tissues, and there was a classic color changes on the fingers (see symptoms).
The disease is much more frequent in countries with cool and humid climate as Denmark.

Raynaud's disease may debut in child age, and occurs predominantly in females. The mode can absorb and move on with age. The mode is believed to occur in up to 20% of all younger women.

A certain proportion of these women will develop later treatment connective tissue (see below), but much experience no other symptoms associated with the disease.

Kar-passport programs can be triggered by people working with the sledgehammer blow or shake the tool. It is called Raynaud's phenomenon, if there is an underlying cause of passport problems.

The phenomenon can occur in association with certain autoimmune connective tissue diseases (eg. Scleroderma and ledegigt).
This is because the state an obstruction of the small arterioles, and there is no vascular spasm.

The mode can also be triggered by high blood pressure in the pulmonary circulation, or by consumption of blood-drawing together medicine.

Since nicotine get blood vessels to pull together, smoking can also trigger a Raynaud case.

Symptoms of Raynaud's syndrome

RAYNAUD attack is illustrated by a very typical symptom pattern.
Tanks are closing, so no blood may flow to the fingers. First, the white wax (livide), Since all the blood in my fingers has disappeared. When you saying? Of the attack, the tanks opened slightly, and the blood flowing through quickly becomes afiltet of the ilthungrende tissues. The fingers are dark blue (cyanotic). Finally, when the artery open again, the fingers højrøde, due to the increased compensatory blood flow to fingers (post ischemic hyperaemia).

The livide phase accompanied by stiff, cold and feeling solve fingers. In the cyanotic phase will be tingling, cold and pain in the fingers. There is a pronounced heat in the fingers in the højrøde phase.

Seizures can last from a few minutes up to several hours.


In severe cases can cause complications associated with lack of oxygen in tissue. This is shown by ulceration, and in the worst case dry gangræn, which can lead to loss of the utmost of your fingers.

Precautions and diagnosis

If you are exposed to attacks of Raynaud type, it is important to keep his fingers and possibly. toes sufficiently hot and dry. Termohandsker and socks can be recommended. Keep simultaneously, as far as possible, the whole body warm, since cases can occur when one has cooled, even though his hands are protected.

Smoking should be avoided as the nicotine can cause seizures.

Have we found work-related Raynaud (by powerful tool operation), you may need to change jobs. The disease can be registered as a work-related illness.

The diagnosis made by the physician at the typical disease picture. He will then take some blood samples and other tests to rule out an underlying autoimmune connective tissue disease.

Treatment of Raynaud's syndrome

Raynaud's diseasemay be difficult to treat. If smoking cessation and avoidance of cold is not enough, there may be attempted blodkarudvidende treatment with medication (calcium channel blockers, possibly. Adrenaline blockers).

In the worst cases, you can try to persuade cutting the small nerves that go to the blood vessels, hoping to avoid passport problems. Raynaud's disease is overwhelmingly safe, and a disease most learn to live with.

Raynaud's phenomenontreated as Raynaud's disease. Is there an underlying autoimmune disease, treated this with immunosuppressive agents.
