Thromboangiitis obliterans in the 21st century--a new face of disease.

Thromboangiitis obliterans (TAO) is a relatively rare disease of peripheral blood vessels, affecting small and medium sized arteries and veins. Although the first description of the disease was given by Winiwarter almost 130 years ago, etiology of TAO remains not elucidated. Smoking is considered as a precipitating factor of the disease. We emphasised some particular features of the new face of TAO - significant decrease in incidences, increased disease prevalence among women and coexistence of other than smoking atherosclerotic risk factors (especially disturbances of glucose metabolism). Contemporary methods of treatment were also discussed.
