Peripheral vascular disease (PVD) is a condition that affects the blood vessels outside of the heart and brain. It occurs when the arteries that carry blood to the arms, legs, and other parts of the body become narrowed or blocked. This can lead to a number of serious health problems, including pain, numbness, and tissue damage.

Causes of Peripheral Vascular Disease

There are a number of factors that can contribute to the development of PVD, including:

Age: The risk of PVD increases with age.
Smoking: Smoking damages the blood vessels and increases the risk of PVD.
High blood pressure: High blood pressure can damage the blood vessels and increase the risk of PVD.
High cholesterol: High cholesterol can build up in the arteries and narrow them, increasing the risk of PVD.
Diabetes: Diabetes can damage the blood vessels and increase the risk of PVD.
Obesity: Obesity can increase the risk of PVD by increasing the strain on the heart and blood vessels.

Symptoms of Peripheral Vascular Disease

The symptoms of PVD can vary depending on the severity of the condition. Some common symptoms include:

Pain: Pain in the legs, feet, or arms is a common symptom of PVD. The pain can be worse with activity and may improve with rest.
Numbness: Numbness or tingling in the legs, feet, or arms is another common symptom of PVD.
Weakness: Weakness in the legs or arms is a symptom of PVD that can make it difficult to walk or perform other activities.
Skin changes: Skin changes, such as discoloration, dryness, or hair loss, can be a sign of PVD.
Wounds: Wounds that do not heal can be a sign of PVD.

Diagnosis of Peripheral Vascular Disease

PVD is diagnosed based on a physical examination and a medical history. Your doctor may also order one or more of the following tests:

Ankle-brachial index (ABI): An ABI compares the blood pressure in your ankle to the blood pressure in your arm. A low ABI can be a sign of PVD.
Doppler ultrasound: A Doppler ultrasound uses sound waves to create images of your blood vessels. This test can show if your blood vessels are narrowed or blocked.
Angiography: Angiography is a procedure that uses X-rays to create images of your blood vessels. This test can show if your blood vessels are narrowed or blocked.

Treatment for Peripheral Vascular Disease

The treatment for PVD depends on the severity of the condition. Treatment options may include:

Lifestyle changes: Lifestyle changes, such as quitting smoking, eating a healthy diet, and exercising, can help to improve PVD symptoms.
Medications: Medications, such as blood thinners and cholesterol-lowering drugs, can help to prevent blood clots and reduce the risk of further narrowing of the arteries.
Surgery: Surgery may be necessary to treat severe PVD. Surgery options include angioplasty, which is a procedure to widen narrowed arteries, and bypass surgery, which is a procedure to create a new pathway for blood to flow around blocked arteries.

Outlook for People with Peripheral Vascular Disease

The outlook for people with PVD depends on the severity of the condition and how well it is treated. With proper treatment, most people with PVD can live full and active lives. However, PVD can increase the risk of developing other serious health problems, such as heart attack and stroke. It is important to follow your doctor's instructions and make lifestyle changes to reduce your risk of complications.

Additional Information about Peripheral Vascular Disease

If you are experiencing symptoms of PVD, it is important to see your doctor right away. Early diagnosis and treatment can help to prevent serious complications. For more information about PVD, please visit the following websites:
