Peripheral Vascular Disease

What Is Peripheral Vascular Disease? 

Peripheral vascular disease (PVD) is a blood circulation disorder that causes the blood vessels outside of your heart and brain to narrow, block, or spasm. This can happen in your arteries or veins. PVD typically causes pain and fatigue, often in your legs, and especially during exercise. The pain usually improves with rest.

It can also affect the vessels that supply blood and oxygen to you:

• Arms
• Stomach and intestines
• Kidneys

In PVD, blood vessels become narrowed and blood flow decreases. This can be due to arteriosclerosis, or “hardening of the arteries,” or it can be caused by blood vessel spasms. In arteriosclerosis, plaques build up in a vessel and limit the flow of blood and oxygen to your organs and limbs.

As plaque growth progresses, clots may develop and completely block the artery. This can lead to organ damage and loss of fingers, toes, or limbs if left untreated.

Peripheral arterial disease (PAD) develops only in the arteries, which carry oxygen-rich blood away from the heart. According to the CDC, approximately 12 to 20 percent of people over age 60 develop PAD, about 8.5 million people trusted Source in the United States. PAD is the most common form of PVD, so the terms are often used to mean the same condition.

• PVD is also known as:
• Arteriosclerosis obliterans
• Arterial insufficiency of the legs
• Claudication
• Intermittent claudication

What Are The Types of PVD?

Functional PVD

Your vessels naturally widen and narrow in response to your environment. But in functional PVD, your vessels exaggerate their response. Raynaud’s disease, when stress and temperatures affect your blood flow, is an example of functional PVD.

The most common causes of functional PVD are:

• Emotional stress
• Cold temperatures
• Operating vibrating machinery or tools
• Drugs

Organic PVD

Organic PVD means there’s a change in the structure of your blood vessels. For example, the plaque buildup from arteriosclerosis can cause your blood vessels to narrow. The primary causes of organic PVD are:

• Smoking
• High blood pressure
• Diabetes
• High cholesterol

Additional causes of organic PVD include extreme injuries, muscles or ligaments with abnormal structures, blood vessel inflammation, and infection.
