Which one is Not true regarding Buerger’s disease?
**Core Concept**
Buerger's disease, also known as thromboangiitis obliterans, is a rare disorder characterized by inflammation and thrombosis of small and medium-sized arteries and veins, typically affecting the limbs. It is strongly associated with smoking and has a predilection for young male smokers.
**Why the Correct Answer is Right**
Buerger's disease is a non-atherosclerotic, non-inflammatory vascular disorder that primarily affects the distal parts of the limbs. The pathophysiology involves endothelial dysfunction, platelet activation, and the release of various vasoactive substances. The disease is often resistant to medical therapy and requires smoking cessation for management.
**Why Each Wrong Option is Incorrect**
**Option A:** This statement might be true, as Buerger's disease can cause inflammation and thrombosis of small and medium-sized arteries and veins. However, it does not exclusively cause vasculitis, which is a broader term encompassing various inflammatory conditions affecting blood vessels.
**Option B:** This statement is true, as smoking is a major risk factor for Buerger's disease. However, it does not address the question of what is not true regarding the disease.
**Option C:** This statement is true, as Buerger's disease often affects the distal parts of the limbs. However, it does not directly address the question of what is not true regarding the disease.
**Clinical Pearl / High-Yield Fact**
A key feature of Buerger's disease is its resistance to medical therapy, and smoking cessation is essential for management. The disease often requires surgical or endovascular interventions to alleviate symptoms.
**Correct Answer:** D.
