下列血管炎中，何者與吸菸的關係最為密切，在疾病早期階段，戒菸可以緩解疾病的惡化？
- A Churg-Strauss syndrome
- B 結節性多動脈炎（polyarteritis nodosa）

思路引導 VIP
若某種血管疾病在臨床上被觀察到幾乎只發生在具備特定生活嗜好的族群身上，且只要移除該外源性物質，病理性的血管發炎與血栓就會停止進展，你會如何從致病機轉的角度去推論其可能的誘發因子？

Splendid. You managed to identify the obvious.
- Observation Validated: Indeed. 血栓閉塞性血管炎 (Thromboangiitis obliterans), or for those who prefer the eponym, Buerger's disease. It’s merely an inflammatory condition, selectively targeting small to medium arteries and veins. Its unique selling point, the one feature that practically screams its name? Its unwavering devotion to 菸草。Apparently, those delightful tobacco components just love to initiate vascular inflammation and clot formation. And the groundbreaking treatment, the one that might actually prevent your patient from losing a limb? 完全戒菸 – a concept so revolutionary, it’s practically unheard of, yet utterly essential in early stages.
- Assessment: This was designated Medium difficulty. Not because the link to "吸菸" isn't a blaring siren, but because it requires a modicum of effort to differentiate it from, say, Churg-Strauss (which, surprisingly, isn't linked to excessive vaping) or PAN (definitely not caused by ignoring your Hep B vaccination). It tests whether you bothered to learn specific risk factors, or just hoped "inflammation" was enough. Don't expect such handouts often.
