Understanding Peripheral Artery Disease with Texas Endovascular

En Español

Finding the underlying cause of your symptoms and providing the treatment you need—sooner.

Lower extremity peripheral artery disease (PAD) is a circulatory condition that affects about 10% of the population.

Although some patients may not experience symptoms, 30% to 40% of those with moderate to severe PAD cases will. Symptoms are often overlooked or attributed to aging or inactivity; however, if you are experiencing any unusual leg symptoms regularly, it’s best to get checked.

If you’ve been recently diagnosed with PAD, need detailed answers to questions like “What is PAD?” or are experiencing symptoms consistent with the condition, our team of vein specialists at Texas Endovascular is here for you.

Let’s explore PAD, including its symptoms, causes, risk factors, and preventions.

What Is PAD?

Peripheral Artery Disease (PAD) is a circulatory disease that occurs when narrowed arteries in the legs or arms reduce blood flow throughout the body.

When this happens, the body cannot keep up with its standard demands, leading to various symptoms, including leg pain.


The most common cause of PAD is plaque buildup inside the arteries.

This plaque consists of cholesterol, calcium, fibrin, and fatty substances. It causes the arteries to narrow and harden, a condition known as atherosclerosis.

When this happens, blood flow is extensively reduced to vital organs and limbs, preventing them from keeping up with the body’s demands.

Since plaque narrows arteries and prevents the blood from flowing as it should, a blood clot can form on the plaque’s surface, or a piece of the plaque can break off and stop the flow completely, resulting in a heart attack or stroke.

Other less common causes of PAD include:

No matter the cause, PAD limits the flow of oxygen-containing blood to the legs, which can cause painful and debilitating symptoms.

Common Risk Factors

The primary risk factor for PAD is tobacco use.

Other common risk factors include:

Signs and Symptoms of PAD

Individuals with PAD do not always experience symptoms due to the disease gradually worsening over many years.

Individuals with PAD often experience mild cramping and leg pain early on during active periods of walking or running. This pain can usually be relieved by resting the legs but will return once the activity is resumed.

Too often, patients do not seek professional care until their health worsens to the point that symptoms become severe and debilitating.

The most common symptoms of PAD include:

Don’t live with unanswered questions like, “Could my symptoms be PAD” and “What is PAD, anyway?” Contact Texas Endovascular at the first sign of unusual leg pain during normal daily activities, like walking.

With simple diagnostic testing and minimally invasive treatments available, there is no need to avoid activities you love to keep your leg pain under control.

Who Is at Risk for PAD?

PAD is a common disease among Americans and can affect anyone at anytime.

Smokers and those with diabetes have the highest risk of developing PAD. Other factors that increase your risk include:


If left untreated, PAD could result in severe and potentially life-threatening consequences, including:


The best way to reduce your risk of developing PAD or mitigate the severity of your symptoms is to live a healthy lifestyle by:
