Buerger's Disease

The Concept

Buerger's disease (thromboangiitis obliterans) is an inflammatory, thrombotic occlusive disease of the small and medium arteries and veins of the limbs. It is distinct from ordinary atherosclerosis, being an inflammatory 'vasculitic' process, and it has a very characteristic patient: the young male heavy smoker. Its defining and overwhelming association is with smoking, which both causes and drives the disease.

Clinical Features

It presents with distal limb ischaemia — claudication (often of the instep/foot), rest pain, and digital ulceration or gangrene of the fingers and toes. Two associated features are characteristic: recurrent superficial thrombophlebitis (migratory, tender vein segments) and Raynaud's phenomenon. Because it affects distal vessels, the peripheral (digital) circulation is lost while proximal pulses may be preserved.

Management

The single most important intervention is absolute and complete cessation of smoking — this is essential and can halt progression, whereas continued smoking leads inexorably to further tissue loss and amputation. Other measures — analgesia, wound care and vasodilators — are supportive, and the distal nature of the disease means it responds poorly to revascularisation. Thus stopping smoking is not merely advice but the definitive treatment.

Histology & Diagnosis

Buerger's disease has a characteristic segmental, inflammatory thrombotic occlusion that, unlike atherosclerosis, spares the vessel wall's structure and affects both arteries and veins with a relatively cellular, inflammatory thrombus. Diagnosis is largely clinical (the young male smoker with distal ischaemia and the supporting features), supported by angiography showing distal, segmental occlusions with 'corkscrew' collaterals and by excluding atherosclerosis, embolic sources and autoimmune disease.

The Bottom Line

Buerger's disease is an inflammatory occlusive disease of the young male smoker causing distal ischaemia, digital gangrene, thrombophlebitis and Raynaud's, whose only effective treatment is absolute smoking cessation.

A Note on Prognosis with Smoking

The prognosis of Buerger's disease is dictated almost entirely by smoking behaviour: patients who achieve complete, permanent cessation usually see the disease arrest, with no further tissue loss, whereas those who continue — even a few cigarettes — progress to repeated digital ulceration, gangrene and amputations. No drug or operation matches the effect of stopping smoking. This stark relationship makes intensive, sustained support for smoking cessation the entire foundation of management.

Absolute cessation of smoking is the only effective treatment.

• Buerger's disease (thromboangiitis obliterans) = inflammatory thrombotic occlusion of small/medium limb arteries and veins.
• Classic: young male heavy smoker; strongly smoking-related.
• Distal ischaemia (instep claudication, rest pain, digital ulcers/gangrene) + migratory superficial thrombophlebitis + Raynaud's.
• Absolute smoking cessation is essential and can halt progression; poor response to revascularisation (distal disease).
