Buerger Disease (Thromboangiitis Obliterans)

Buerger disease, also known as thromboangiitis obliterans, is a rare inflammatory condition that affects the small- and medium-sized arteries and veins in the arms and legs. It leads to blood vessel narrowing, blockage, and eventually tissue damage due to restricted blood flow. The condition is strongly associated with tobacco use and most often affects young to middle-aged men who smoke or use other tobacco products.

Buerger disease progresses in stages:

• Early Stage – Inflammation causes narrowing of blood vessels, leading to pain or cold sensitivity.
• Intermediate Stage – Blocked blood flow can cause sores or ulcers on the fingers or toes.
• Advanced Stage – Tissue death (gangrene) may occur, increasing the risk of infection or amputation.

The exact cause is unknown, but the condition is strongly linked to:

• Tobacco Use – Smoking or chewing tobacco is the primary risk factor.
• Male Gender – Most common in men under 45.
• Genetic Predisposition – May run in families or certain ethnic groups like those of Asian or Middle Eastern descent.
• Chronic Gum Disease – Emerging evidence suggests a possible link between long-term infection of gums in the mouth but more studies need to confirm this link.

Symptoms of Buerger disease include:

• Pain in the fingers or toes, especially when walking (claudication)
• Coldness or numbness in the fingers or toes
• Skin color changes (pale, red or bluish)
• Painful open sores or ulcers on fingers or toes
• Gangrene in advanced cases

Symptoms often worsen with continued tobacco use.

Diagnosis involves ruling out other causes of vascular disease. Common tests include:

• Blood Tests – To exclude autoimmune or clotting disorders.
• Angiography – Imaging to detect blockages or narrowed vessels.
• Allen Test – A bedside exam used to check blood flow in hands.
• Doppler Ultrasound – A noninvasive imaging technique to visualize blood flow in the limbs.

Diagnosis is confirmed based on clinical history, imaging, and the exclusion of other diseases.

There is no cure, but treatment focuses on stopping disease progression and managing symptoms:

• Complete Smoking Cessation – The single most important step to halt progression.
• Medications – Improve blood flow and reduce inflammation.
• Vascular Rehabilitation – Improves circulation through supervised therapy.
• Surgical Options – May include bypass surgery or, in severe cases, amputation.
• Pain management – Often needed as disease progresses.
• Wound Care – For ulcers or sores that develop on the skin.

Without treatment, Buerger disease can lead to:

• Tissue Death (Gangrene)
• Infections in limbs
• Amputation of fingers, toes, or limbs
• Reduced mobility and quality of life

The best prevention is to avoid all forms of tobacco. Additional preventive measures include:

• Practicing good foot and hand care
• Staying physically active
• Managing underlying conditions (e.g., diabetes or cholesterol)
• Seeing a vascular specialist regularly
