Understanding Peripheral Artery Disease with Texas Endovascular

En Español

Getting to the bottom 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 any 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.

We can help reduce chronic symptoms and your risk for complications through state-of-the-art diagnosis and treatment options without requiring lengthy hospital stays or extended recovery times.

Don’t delay—get the diagnosis and care you need now.

Let’s explore PAD, including its symptoms, risk factors, treatment options, and prevention steps, in further detail.

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 being able to keep 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:

  • Blood vessel inflammation
  • Injury to the arms or legs
  • Changes in the muscles or ligaments of the arms or legs
  • Radiation exposure

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

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:

  • Coldness or numbness of the legs and feet
  • Discoloration in the legs
  • Cramping of the hips, thighs, or calf muscles
  • Difficulty in healing from minor wounds of the legs or feet
  • Burning or aching sensations of the feet
  • Poor toenail growth
  • Pain while or soon after walking
  • Slowed hair growth on the legs
  • Erectile dysfunction

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 that occurs 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.


PAD is diagnosed with a bedside test called an Ankle-Brachial Index (ABI), which uses ultrasound and blood pressure cuffs to evaluate the circulation in your arms and legs.

If this test is abnormal, we may order further imaging tests such as Magnetic Resonance Angiography (MRA) or Computed Tomography (CT) to determine the extent of your problem and help us plan your treatment.

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:

  • A family history of PAD, heart disease, or stroke
  • High blood pressure
  • High cholesterol
  • Age, especially those over 65
  • Obesity
  • An increased level of homocysteine, which increases the risk of coronary artery disease


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

  • Heart attack
  • Stroke
  • Gangrene
  • Critical limb ischemia (an infection that causes tissue to die), which could lead to amputation or limb loss


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

  • Not smoking
  • Eating a healthy balanced diet, low in saturated fat
  • Controlling your blood sugar
  • Exercising regularly
  • Maintaining a healthy weight
  • Monitoring and managing your cholesterol and blood pressure
