Thromboangiitis obliterans is a rare disease in which blood vessels of the hands and feet become obstructed.
Thromboangiitis obliterans (Buerger's disease) is caused by vasculitis (inflammation of the blood vessels).
The blood vessels of the hands and feet are especially affected, becoming constricted or totally blocked. This reduces blood flow to the hand and foot tissues, resulting in pain and eventually damage.
Thromboangiitis obliterans affects about 6 of every 10,000 people. It almost always affects men ages 20 to 40 who have a history of smoking or chewing tobacco.
The condition may also be associated with a history of Raynaud's disease.
This disorder is very uncommon in children, but may occur in those with autoimmune diseases.
Note: Symptoms may worsen with exposure to cold or with emotional stress. Usually, two or more limbs are affected.
The hands or feet may show enlarged, red, tender blood vessels. The pulse in the affected hands or feet may be low or absent.
The following tests may show blockage of blood vessels in the affected hands or feet:
Blood tests for other causes of vasculitis and inflammation may be done. Rarely, in cases where the diagnosis is unclear, a biopsy of the blood vessel is done.
There is no cure for thromboangiitis obliterans. The goal of treatment is to control symptoms.
To prevent amputation, the patient must stop using tobacco and should avoid cold temperatures and other conditions that reduce circulation to the hands and feet.
Applying warmth and exercising gently may help increase circulation.
Cutting the nerves to the area (surgical sympathectomy) may help control pain. Aspirin and vasodilators may also used. Amputation of the extremity may be necessary if infection or extensive tissue death occurs.
Symptoms of thromboangiitis obliterans may disappear if the person stops tobacco use. For some, amputation is unavoidable.
Call your health care provider if you have symptoms of thromboangiitis obliterans, if you have thromboangiitis obliterans and symptoms get worse despite treatment, or if new symptoms develop.
Those with a history of Raynaud's disease or thromboangiitis obliterans should avoid all tobacco use.
