What the heck is peripheral vascular disease really?

Blockage of arteries: Plaque consisting of cholesterol, fats, and calcium may build up inside of the arteries, usually those providing flow to the legs but also the kidneys, intestine of brain (carotid arteries). This is most common in people with diabetes, abnormal cholesterol, hypertension, and a history of smoking. These blockages can often be treated through a catheter with plaque removal or stents.

Narrow arteries: Peripheral vascular or peripheral arterial disease refers to a pathologic process where the arteries are weakened damaged or blocked. This is typically caused by plaque build up which is exacerbated by diet and smoking.
