Buerger's Disease

Definition

Definition of Buerger's Disease
Buerger's disease (thromboangiitis obliterans) is a rare disease of the arteries and veins in the arms and legs. In Buerger's disease, your blood vessels become inflamed, swell and can become blocked with blood clots (thrombi). This eventually damages or destroys skin tissues and may lead to infection and gangrene. Buerger's disease usually first shows in the hands and feet and may eventually affect larger areas of your arms and legs.

Buerger's disease is rare in the United States, but is more common in the Middle East and Far East. Buerger's disease usually affects men younger than 40 years of age, though it's becoming more common in women.

Virtually everyone diagnosed with Buerger's disease smokes cigarettes or uses other forms of tobacco, such as chewing tobacco. Quitting all forms of tobacco is the only way to stop Buerger's disease. For those who don't quit, amputation of all or part of a limb may be necessary.

Symptoms

Symptoms of Buerger's Disease
The initial symptoms of Buerger’s Disease often include claudication (pain induced by insufficient blood flow during exercise) in the feet and/or hands, or pain in these areas at rest. The pain typically begins in the extremities but may radiate to other (more central) parts of the body. Other signs and symptoms of this disease may include numbness and/or tingling in the limbs and Raynaud’s phenomenon (a condition in which the distal extremities - fingers, toes, hands, feet - turn white upon exposure to cold). Skin ulcerations and gangrene of the digits (fingers and toes) are common in Buerger’s disease. Pain may be very intense in the affected regions.

Causes

Causes of Buerger's Disease
The association of Buerger’s Disease with tobacco use, particularly cigarette smoking, cannot be overemphasized. Most patients with Buerger’s are heavy smokers, but some cases occur in patients who smoke “moderately”; others have been reported in users of smokeless tobacco. It has been postulated that Buerger’s Disease is an “autoimmune” reaction (one in which the body’s immune system attacks the body’s own tissues) triggered by some constituent of tobacco.

Diagnosis

Diagnosis of Buerger's Disease
Buerger’s disease can be mimicked by a wide variety of other diseases that cause diminished blood flow to the extremities. These other disorders must be ruled out with an aggressive evaluation, because their treatments differ substantially from that of Buerger’s Disease.

Diseases with which Buerger’s Disease may be confused include atherosclerosis (build–up of cholesterol plaques in the arteries), endocarditis (an infection of the lining of the heart), other types of vasculitis, severe Raynaud’s phenomenon associated with connective tissue disorders (e.g., lupus or scleroderma), clotting disorders of the blood, and others.

Angiograms of the upper and lower extremities can be helpful in making the diagnosis of Buerger’s disease. In the proper clinical setting, certain angiographic findings are diagnostic of Buerger’s. These findings include a “corkscrew” appearance of arteries that result from vascular damage, particularly the arteries in the region of the wrists and ankles. Angiograms may also show occlusions (blockages) or stenoses (narrowings) in multiple areas of both the arms and legs.

Treatment

Treatment of Buerger's Disease
Although no treatment can cure Buerger's disease, the most effective way to halt the disease's progress is to quit using all tobacco products. Even a few cigarettes a day can worsen the disease.

Your doctor can counsel you and recommend medications to help you stop smoking and stop the swelling in your blood vessels. You'll need to avoid nicotine replacement products because they supply nicotine, which activates Buerger's disease; there are non-nicotine products that you can use. If the disease is still active, your doctor may check your urine for the presence of nicotine to see if you're still smoking.

Another option is a residential smoking-cessation program. In these programs, you stay at a treatment facility, sometimes a hospital, for a set number of days or weeks. During that time you participate in daily counseling sessions and other activities to help you deal with the cravings for cigarettes and to help you learn to live tobacco-free.

Prevention

Prevention of Buerger's Disease
Virtually everyone who has Buerger's disease has used tobacco in some form, most prominently cigarettes. To prevent Buerger's disease, it's important to not use tobacco.
