Thromboangiitis obliterans (Buerger's disease) with intestinal involvement--a case report.

Thromboangiitis obliterans (TAO) or Buerger's disease is a nonatherosclerotic vascular disease of unknown etiology that occurs almost exclusively in young male tobacco users. The involvement of the medium-sized and small arteries and veins leads to ischemic complaints and trophic changes in the limbs. The authors report a case of Buerger's disease in a 29-year-old man, a heavy smoker, affecting the lower limbs and mesenteric vessels.
