A 30-year-old man with claudication and a long smoking history. Which disease is most likely and what is the cornerstone of therapy?

• A. Atherosclerotic PAD; statin therapy
• B. Takayasu arteritis; steroids
• C. Buerger's disease; smoking cessation
• D. Raynaud phenomenon; vasodilators

Answer: (C)

Think thromboangiitis obliterans (Buerger’s disease) when a young man with a long smoking history develops claudication. This is a nonatherosclerotic inflammatory occlusive disease that targets small- to medium-sized arteries and veins in the extremities, often with nerve involvement, leading to ischemic symptoms like claudication or rest pain. The strongest clue is the association with heavy tobacco use in a younger patient, which drives the disease. The cornerstone of therapy is complete smoking cessation. Stopping tobacco exposure can halt disease progression and markedly reduce the risk of limb loss; it addresses the root cause of this condition. Other treatments, such as statins or steroids, don’t address the underlying vasculitis driven by smoking and are not as effective for this disease. Revascularization is frequently not feasible because the disease involves distal vessels, and vasodilators or antiplatelet therapies may help symptomatically but do not change the disease course as effectively as smoking cessation. So, the most likely diagnosis is Buerger’s disease, and the essential management step is quitting smoking.
