Peripheral Arterial Disease (PAD)

Peripheral Artery Disease Is a Form of Vascular Disease

Peripheral arterial disease (PAD) is a common form of vascular disease that develops when plaque builds up along the walls of the arteries, causing them to narrow over time. These arteries are responsible for carrying oxygen-rich blood from the heart to the rest of the body.

As plaque accumulates, it can restrict the flow of blood, oxygen, and nutrients. This reduced circulation may lead to discomfort, particularly in the legs, where muscles and tissues rely on consistent blood flow for proper function.

While PAD most commonly affects the lower extremities, it can also impact other areas of the body, including the arms, abdomen, and other organs.

Symptoms of Peripheral Arterial Disease

PAD symptoms can vary from person to person and may develop gradually. One of the most common signs is claudication, which refers to cramping or discomfort in the legs during activity.

Symptoms may include:

Leg pain or cramping while walking

Fatigue or heaviness in the legs

Numbness or weakness

Coldness in the feet or lower legs

Foot or toe discomfort at rest

Slow-healing wounds on the legs, feet, or toes

Changes in skin color or texture

Weak or diminished pulse in the legs

Slower toenail growth

Pain in the arms during activity

Symptoms often improve with rest, but persistent or worsening discomfort should be evaluated by a vascular specialist.

Causes of Peripheral Arterial Disease

PAD is primarily caused by atherosclerosis, where fatty deposits build up in the arteries, reducing blood flow to the limbs. The lack of blood flow to the limbs is what classifies PAD. Less common causes of PAD include inflammation of the blood vessels, injury to the limbs, exposure to radiation, and general changes to the muscles or ligaments in the limbs.

Peripheral Arterial Disease Risk Factors

Several factors may increase the likelihood of developing PAD, including:

Smoking

Diabetes

High blood pressure

High cholesterol

Family history of vascular disease

Sedentary lifestyle

Understanding these risk factors can help guide both prevention and treatment strategies.

Diagnosing Peripheral Arterial Disease

At Pedes Orange County, we provide comprehensive evaluation and diagnostic testing for PAD using advanced vascular imaging and in-office testing.

Our diagnostic process may include:

Detailed Physical Examination

Your physician will review your medical history, symptoms, and lifestyle factors. A physical exam may include checking pulses, circulation, and skin condition in the legs and feet.

Ankle-Brachial Index (ABI)

A simple, non-invasive test that compares blood pressure in the arms and legs to assess circulation.

Arterial 
Ultrasound

Ultrasound imaging is used to evaluate blood flow and identify areas of narrowing or blockage.

Angiography

Conditions such as diabetes, high blood pressure, and vascular disease can impact healing.

Blood Tests & MRA

Additional testing may be used to evaluate overall vascular health and identify contributing factors.
