Buerger's disease or thromboangiitis obliterans

The Buerger's disease or thromboangiitis obliterants (TAO) is a non atheromatous inflammatory disease which alters medium and small-sized arteries and veins. It can be found world-wide, but it is more frequent in Eastern Europe, Middle East, Asia and Southeast Asia. Young men and smokers are the most affected. The incidence of this disease is increasing among women. The cause of this disease is unknown yet. The most striking fact is the relationship between TAO and tobacco. The diagnostic is most often late in front of a digital leg ischemia. Complementary exams help to its diagnostic and management but none of them are specific out of the pathology. The affection is evolving towards distal gangrene with amputation in 5 to 10% of cases. Prostacyclin demonstrated its efficiency. Revascularization surgery is difficult but sometimes possible. Sympathectomy, medular stimulation must be suggested. The patient survival is not at stake and the prognosis is above all functional. The most important element in the treatment is stop smoking definitively.
