Thromboangiitis obliterans, abbreviated TAO, is a rare vascular disease characterized by recurrent thrombosis. It primarily afflicts young smokers and is also known as Buerger disease.

It should not be confused with Berger disease (IgA nephropathy).

General

  • Strong association with smoking.[1]
  • Clinical-radiologic diagnosis.[2]

Typical symptoms/signs - progression:[3]

Treatment:

  • Stop smoking.[3]

Formal clinical criteria

Simple

All of the following - as per Shionoya:[4]

  • Smoking.
    • No other atherosclerosis risk factors.
  • Onset < 50 years old.
  • Infrapopliteal arterial occlusions.
  • Arm involvement or phlebitis migrans;

Complicated

All of the following - as per Olin:[5]

  • Less than 45 years old.
  • Current or recent tobacco use.
  • Sign or symptoms of distal extremity ischemia (claudication, pain at rest, ulcers, gangrene).
  • Arteriographic findings consistent with the disease.

Exclusions - with lab tests:[4]

  • Autoimmune disease.
  • Hypercoagulable state.
  • Diabetes mellitus.
  • Radiographic findings suggestive of proximal emboli source (echocardiography, arteriography).

Gross

  • Afflicts small and medium-sized vessels of the extremities.
  • Corkscrew vessels - seen on angiography.[2]

Microscopic

Features:[6]

  • Acute inflammation:
    • Endarteritis - neutrophils at the internal elastic lamina (IEL).
    • Periarteritis - neutrophils around the arteries.
  • Luminal narrowing due to thrombi.[4]
    • Organizing thrombi = thickened tunica intima.
    • Vessels may be re-canalized.

Notes:

  • Typically segmental.[3]
