Buerger's disease: diagnosis and management.

Buerger's disease is characterized by peripheral arterial occlusion of the extremities in young male smokers. In true Buerger's disease lesions rarely occur in the proximal arteries. The incidence of the disease is low in Europe and the USA, but its management remains a major problem for vascular surgeons in Asia where its incidence is higher. Aetiology of the disease remains unknown, but there is a clear relationship between tobacco abuse and its occurrence or recurrence; complete cessation of smoking renders the disease benign. Despite a high incidence of digital gangrene or ulceration, a functional foot or hand can generally be preserved because of the good healing potential of the trophic lesions. Specificity of the disease is characterized by peripheral ischaemia of an inflammatory nature and with a self-limiting course. The clinical term Buerger's disease is preferred to the pathological term thromboangiitis obliterans. Diagnosis is based on knowledge of the natural history of the disease, which aids prognosis and the decision to undertake surgical or conservative management. Treatment of Buerger's disease should avoid premature, possibly unnecessary, surgery. The condition is no longer a disease of misconceptions; its diagnosis and management should be based on a clear understanding of the pathophysiology.
