Because a firm diagnosis of thromboangiitis obliterans (TAO; also referred to as Buerger disease), is difficult to establish, a number of different diagnostic criteria have been proposed. [7] In 1990, Olin et al asserted that the following criteria must be met for the diagnosis to be made with reasonable certainty [8] :

  • Age younger than 45 years
  • Current (or recent) history of tobacco use
  • Presence of distal extremity ischemia (indicated by claudication, pain at rest, ischemic ulcers, or gangrene) documented by noninvasive vascular testing
  • Exclusion of autoimmune diseases, hypercoagulable states, and diabetes mellitus by laboratory tests
  • Exclusion of a proximal source of atheroemboli by echocardiography and arteriography
  • Consistent arteriographic findings in the clinically involved and noninvolved limbs
