Thromboangiitis obliterans, commonly known as Buerger’s disease, is a rare but serious inflammatory condition that primarily affects the small and medium-sized blood vessels in the arms and legs. Over time, this inflammation leads to blood vessel blockage due to clot formation (thrombosis), which restricts blood flow to the hands, feet, and sometimes even the lower limbs. The reduced circulation causes pain, tissue damage, and, in severe cases, gangrene, which may require amputation if left untreated.
Causes and Risk Factors
-
Genetic predisposition – certain populations, especially in Asia and the Middle East, have higher incidence rates.
-
Autoimmune mechanisms – the immune system may mistakenly attack blood vessel walls.
-
Chronic infection or hypersensitivity to tobacco components.
It is important to note that nearly all patients diagnosed with Buerger’s disease are current or former heavy smokers, underlining the central role of tobacco in the disease process.
Symptoms and Early Warning Signs
Buerger’s disease typically affects young to middle-aged men under 45, although it can occur in women as well. The symptoms usually begin in the hands, feet, fingers, or toes, and include:
-
Pain in the limbs (especially during rest or at night)
-
Tingling or numbness in the fingers or toes
-
Cold sensitivity in the extremities
-
Skin color changes (pale, bluish, or reddish)
-
Development of non-healing ulcers or sores on fingers and toes
-
Claudication – cramping pain when walking or using the affected limb due to poor blood flow
As the disease progresses, the restricted blood supply can lead to tissue death (necrosis), which is extremely painful and can result in amputation if not managed promptly.
Diagnosis
There is no single test that confirms Buerger’s disease, so doctors rely on a combination of clinical signs, medical history, and imaging studies. Common diagnostic tools include:
-
Angiography (CT or MR angiogram) – to visualize blocked or narrowed arteries.
-
Blood tests – to rule out autoimmune diseases or other vascular disorders.
-
Allen’s test – a simple bedside test to assess blood flow in the hands.
A hallmark finding is a “corkscrew” appearance of blood vessels on angiography, indicating segmental inflammation and clot formation.
Treatment and Management
The most critical and effective treatment for Buerger’s disease is complete and permanent cessation of all tobacco use. Even minimal smoking or nicotine exposure can cause disease progression or relapse.
Additional management strategies may include:
-
Medications to improve blood flow, such as vasodilators or anticoagulants.
-
Pain management for nerve and tissue discomfort.
-
Exercise therapy to promote circulation.
-
Surgical interventions such as sympathectomy (nerve surgery to improve blood flow) or, in severe cases, amputation of non-viable tissue.
Emerging treatments, like stem cell therapy and angiogenic growth factors, are being researched for their potential to stimulate new blood vessel formation.
Prevention and Lifestyle
-
Regular exercise
-
Balanced diet rich in antioxidants and omega-3s
-
Proper foot and hand care to avoid injuries or infections
-
Avoiding exposure to cold temperatures
Conclusion
Buerger’s disease is a preventable vascular condition with serious consequences if ignored. Early detection and complete tobacco cessation are vital for halting its progression. Raising awareness about this disease—especially among smokers and young adults—can play a crucial role in prevention and early management.
