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
Typical symptoms/signs - progression:[3]
- Intermittent claudication -> ulcers -> gangrene -> amputation.
Treatment:
- Stop smoking.[3]
Formal clinical criteria
All of the following - as per Olin:[4][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:[5][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.
- Obliteration of the lumen.
- Thrombi.
- Organizing thrombi - thickened tunica intima.
Notes:
- Typically segmental.[3]
DDx:
- Peripheral vascular disease (atherosclerosis) - typically lacks the acute inflammation around the IEL and around the vessels.
- Vasculitis - have fibrinoid necrosis.
Images:
