Is peripheral vascular disease the same thing as hypertension?

No. Hypertension is abnormally high blood pressure. This can contribute to a different problem- peripheral vascular disease (otherwise known as pad, "hardening of the arteries, " atherosclerosis, and other names).
No. Hypertension is a sustained elevation in one's blood pressure. Peripheral vascular disease is when you develop plaques in the peripheral arteries that can progress to blockages.
