رجل مدخن عمره ٣٢ سنة عنده ألم في أصابع القدم مع قرح صغيرة وبرودة شديدة. شُخص بمرض بيرجر (التهاب الأوعية الخثاري). ما أهم تدخل لإيقاف تقدم المرض؟

A 32-year-old male smoker has painful, very cold toes with small ulcers and is diagnosed with Buerger’s disease (thromboangiitis obliterans). What is the most important intervention to halt progression?

1. Long-term antibiotics
2. Elevating the legs all night
3. High-dose aspirin alone
4. Complete smoking cessation

Answer: D) Complete smoking cessation. Buerger’s disease is strongly tied to tobacco, and complete cessation is the only intervention that halts progression and prevents amputation. Even light smoking or smokeless tobacco can reactivate it.
