 Understanding Peripheral Artery Disease (PAD)

If you or someone you love has been diagnosed with peripheral artery disease (PAD), you're not alone. Millions of people live with PAD, and today, there are more treatment options than ever to help restore blood flow, relieve symptoms, and protect your limbs.

What is PAD?

Peripheral Artery Disease, or PAD, is a common but serious condition that affects the blood vessels in your legs and feet. It happens when arteries become narrowed or blocked due to a buildup of plaque, a process called atherosclerosis. When blood can’t flow properly, it causes pain, numbness, and even wounds that won’t heal.

PAD is essentially “poor circulation.” Think of your arteries like garden hoses. When debris builds up inside, water can’t flow freely, it trickles instead of streams. Similarly, when your arteries are narrowed, blood struggles to reach your limbs, leading to discomfort and making it harder to stay active or mobile.

The Quick Facts:

  • In severe cases, PAD can lead to ulcers, infections, and even amputation

  • 70% of people are not familiar with what PAD is

  • 200 million adults worldwide have PAD

  • 8 – 10 million adults in the US have PAD

  • 11% of PAD patients are likely to develop Critical limb-threatening ischemia (CLTI).

  • 25% of patients with CLTI require limb amputations within 1 year of diagnosis.

  • 71% of patients with a lower-extremity amputation have a 3-year mortality risk.

Common Symptoms of PAD:

Many people mistake PAD symptoms for normal aging or other issues. Recognizing the signs early is key.

Pain, aches, or cramps when walking
(called claudication)

Coldness in your lower leg or foot

Numbness or weakness in the legs or feet

Lack of growth of your toenails and leg hair

A weak pulse in your legs or feet

Sores on toes, feet, or legs that won’t heal

Shiny skin or slower hair growth on your legs

It's Important to Note:
About 1 in 4 people with PAD have classic symptoms of pain in their legs during activity. Many people with PAD have no symptoms at all, but the disease is still doing damage.

Who's at Risk for Peripheral Artery Disease?

PAD can affect anyone, but you may be at higher risk if you:

  • Smoke or used to smoke

  • Have diabetes or chronic kidney disease

  • Are a person of color

  • Have high blood pressure or high cholesterol

  • Are over 65 years old

  • Have atherosclerosis

  • Have a family history of PAD, heart disease or stroke

Serranator is here to help

The Serranator is designed with tiny, serrated strips that apply pressure more effectively than a plain angioplasty balloon. This allows for the artery to open predictably and in a controlled manner, improving blood flow without causing damage. It also helps keep the artery open, reducing the chance it will collapse (recoil) and lowering the need for a stent.
