Peripheral Artery Disease (PAD) is a serious but often overlooked circulatory condition that affects millions of adults in the United States. It is especially common among people over 50, those living with diabetes or heart disease, and individuals with a history of smoking. Many people live with PAD for years without realizing it, often assuming early symptoms are simply part of aging or being out of shape.
Left untreated, PAD can lead to much more than leg pain. Over time, reduced blood flow can cause chronic discomfort, slow-healing wounds, serious infections, and in advanced cases, limb-threatening complications.
At Innovative Minimally Invasive Imaging & Therapeutics (IMIIT), we focus on advanced, image-guided treatments for PAD that restore healthy blood flow without open surgery. This guide explains what PAD is, why it develops, which symptoms deserve attention, and how minimally invasive treatment can help you return to a more active, comfortable life.

What Is Peripheral Artery Disease (PAD)?
Peripheral Artery Disease is a form of atherosclerosis, a condition in which plaque made up of fat, cholesterol, and calcium gradually builds up inside the arteries. In PAD, this process affects the arteries that supply blood to the legs and feet.
As the arteries narrow, less oxygen-rich blood reaches the muscles and surrounding tissues. Over time, this reduced circulation can interfere with how your legs function and how well your body heals.
When blood flow is limited, you may notice that:
- Leg muscles tire or cramp more quickly
- Walking becomes uncomfortable or painful
- Cuts or sores on the feet heal slowly or not at all
- Pain increases with activity and improves with rest
- In severe cases, tissue damage can threaten limb health
PAD is closely linked to heart disease and is often considered a warning sign that plaque buildup may also be affecting arteries in the heart or brain, increasing the risk of heart attack or stroke.
What Causes Peripheral Artery Disease?
PAD usually develops slowly over many years as the arteries become damaged and narrowed. Plaque buildup is the most common cause, but several factors influence how quickly the disease progresses.
Common Causes and Contributing Factors
- Atherosclerosis, which leads to plaque buildup inside the arteries
- Ongoing inflammation of the blood vessels
- Long-term damage to the artery walls
Risk Factors That Increase the Likelihood of PAD
- Current or past smoking
- Diabetes
- High blood pressure
- High cholesterol
- Obesity
- Limited physical activity
- Age over 50
- Family history of vascular disease
Because PAD can progress quietly, many people do not realize they have it until symptoms begin to interfere with daily life. Early evaluation is especially important if you have more than one risk factor.
Symptoms of Peripheral Artery Disease
Symptoms of PAD can vary from person to person. Some individuals notice early warning signs, while others do not experience symptoms until circulation is significantly reduced.
Common PAD Symptoms
- Leg pain, cramping, or tightness during walking, known as claudication
- Pain in the calves, thighs, hips, or buttocks with activity
- Leg fatigue or weakness
- Coldness in one lower leg or foot compared to the other
- Numbness or tingling
- Reduced walking speed or endurance
These symptoms often improve with rest, which can make PAD easy to ignore at first.
Advanced PAD Symptoms (Critical Limb Ischemia)
As PAD becomes more severe, symptoms may occur even at rest and require urgent attention:
- Ongoing foot or leg pain, especially at night
- Wounds on the toes or feet that do not heal
- Skin that appears pale, shiny, or discolored
- Thickened or brittle toenails
- Hair loss on the legs or feet
- Open sores, ulcers, or gangrene
If leg pain limits your ability to walk or you have wounds that are not healing, it is important to seek vascular care as soon as possible.
How Is PAD Diagnosed?
Diagnosis typically begins with a review of your medical history and a physical exam, followed by non-invasive testing. If needed, advanced imaging helps identify exactly where blood flow is restricted.
Diagnostic tests may include:
- Ankle-Brachial Index (ABI), which compares blood pressure in the ankle and arm
- Doppler ultrasound to evaluate circulation
- CT angiography or MR angiography for detailed images of the arteries
- Diagnostic angiography for precise mapping of blood vessels
At IMIIT, all imaging is performed and interpreted by board-certified interventional radiologists. This allows for accurate diagnosis and thoughtful treatment planning based on your individual anatomy.
Minimally Invasive PAD Treatments at IMIIT
In the past, PAD treatment often required open surgery or bypass procedures. Today, many patients can be treated with minimally invasive, catheter-based techniques that improve blood flow while avoiding large incisions and long recovery times.
At IMIIT, treatment focuses on opening narrowed or blocked arteries using image-guided technology. Endovascular PAD treatments may include:
Angioplasty
A small balloon is guided through a catheter to the narrowed area of the artery and gently inflated to improve circulation.
Stent Placement
In some cases, a small mesh stent is placed to help keep the artery open over time.
Atherectomy
Specialized tools are used to remove plaque from inside the artery. This approach can be particularly helpful when plaque is heavily calcified.
Benefits of Minimally Invasive PAD Treatment
Many patients choose minimally invasive treatment because it offers meaningful relief with fewer disruptions to daily life:
- No large surgical incisions
- Procedures performed through a small catheter
- Shorter recovery times
- Many treatments completed on an outpatient basis
- Lower risk compared to open surgery
- Improved walking ability and reduced pain
- Options focused on preserving the limb in advanced cases

Who Is a Candidate for PAD Treatment?
You may be a candidate for minimally invasive PAD treatment if you:
- Have leg pain that limits walking or everyday activities
- Have diabetes with signs of poor circulation
- Have foot or leg wounds that are slow to heal
- Have been told you are not a good candidate for surgery
- Want to avoid bypass surgery or amputation
At IMIIT, every patient begins with a personalized consultation and imaging evaluation. Treatment decisions are based on your symptoms, imaging results, and overall health.
Why Choose IMIIT for PAD Treatment?
IMIIT is dedicated exclusively to minimally invasive vascular and interventional care and offers patients an alternative to traditional surgical treatment.
What sets IMIIT apart:
- Care provided by board-certified interventional radiologists
- Advanced imaging for precise treatment planning
- A strong focus on restoring circulation and preserving limb health
- Outpatient-based care designed with patient comfort in mind
- Individualized treatment plans tailored to each patient
This focused approach allows IMIIT to treat PAD safely and effectively, even in complex or advanced cases.
When to Seek Help for PAD
If leg pain, numbness, or non-healing wounds are affecting your mobility or quality of life, PAD may be the cause. Addressing circulation problems early can help slow disease progression and reduce the risk of serious complications.
