Peripheral Artery Disease (PAD), sometimes referred to as peripheral vascular disease, is one of the most common circulation disorders affecting adults. Yet, many people do not realize they have it until symptoms become severe. PAD occurs when arteries that supply blood to the legs become narrowed or blocked, usually due to plaque buildup. This reduces blood flow to muscles and tissues, which can lead to pain, limited mobility, and in serious cases, tissue damage.
At the Vascular Institute of Michigan in Flint, our specialists diagnose and treat PAD using advanced imaging and minimally invasive procedures that restore blood flow and help patients avoid major surgery. Understanding the condition is the first step toward protecting your circulation and long-term health.
Peripheral Artery Disease is a circulation disorder caused by narrowed leg arteries that reduce blood flow. Early diagnosis and minimally invasive vascular treatments can relieve symptoms, prevent complications, and improve mobility.
What Is Peripheral Artery Disease?
Peripheral Artery Disease is a form of atherosclerosis, the same process that causes coronary artery disease and heart attacks. Over time, cholesterol, calcium, and inflammatory cells accumulate inside artery walls, forming plaque. As plaque grows, the artery becomes narrower and less flexible.
When this happens in the arteries that supply the legs and feet, muscles do not receive enough oxygen during activity. Patients often notice symptoms when walking or exercising because the body demands more blood flow than the narrowed artery can deliver.
PAD most often affects several major arteries in the legs, including the:
- Femoral arteries in the thighs
- Popliteal arteries behind the knee
- Tibial arteries in the lower leg
Because PAD is linked to systemic atherosclerosis, it can also signal a higher risk of heart attack or stroke. That is why vascular specialists treat PAD not just as a leg condition but as an important indicator of overall cardiovascular health.
Common Symptoms of Peripheral Artery Disease
PAD symptoms can develop gradually, and some people experience very mild warning signs at first. Others may not notice symptoms until the disease becomes advanced.
One of the most recognizable symptoms is claudication, which is leg pain that occurs during walking and improves with rest.
Patients commonly describe the discomfort as:
- Cramping in the calf or thigh
- Aching or heaviness in the legs
- Fatigue when walking short distances
- Burning or tightness in the muscles
The distance a person can walk before symptoms begin often becomes shorter over time.
More advanced PAD symptoms may include:
- Numbness or weakness in the legs
- Coldness in the lower leg or foot
- Slow-healing wounds on the feet or toes
- Shiny skin or hair loss on the legs
- Pain in the legs or feet at rest
In severe cases, reduced circulation can lead to critical limb ischemia, a serious condition that can cause tissue damage or infection.
If you notice persistent leg pain during activity or wounds that will not heal, it is important to see a vascular specialist for evaluation.
Who Is Most at Risk for PAD?
Peripheral Artery Disease can affect anyone, but certain risk factors significantly increase the likelihood of developing the condition.
Smoking remains the strongest risk factor. Tobacco damages artery walls and accelerates plaque formation.
Other common risk factors include:
- Diabetes
- High blood pressure
- High cholesterol
- Obesity
- Sedentary lifestyle
- Family history of vascular disease
- Age over 60
Patients with diabetes are particularly vulnerable because reduced circulation combined with nerve damage can lead to foot ulcers and infections.
Many patients seen at the Vascular Institute of Michigan have several of these risk factors. Early screening and vascular testing help identify PAD before complications occur.
How Peripheral Artery Disease Is Diagnosed
Diagnosing Peripheral Artery Disease usually begins with a discussion about your symptoms and a physical exam. A vascular specialist will check circulation in your legs and feet, evaluate pulses, and look for signs of reduced blood flow such as skin changes or slow-healing wounds. If PAD is suspected, several non-invasive tests can help confirm the diagnosis and determine how severely blood flow is affected.
Ankle-Brachial Index (ABI)
The Ankle-Brachial Index is one of the most common screening tests for PAD. This quick and painless exam compares the blood pressure in your ankles with the blood pressure in your arms. Normally, ankle pressure is close to or slightly lower than arm pressure. When arteries in the legs are narrowed, ankle pressure drops significantly. The test takes only a few minutes and is often performed during a routine vascular evaluation.
Doppler or Duplex Ultrasound
Doppler and duplex ultrasound imaging allow physicians to evaluate how blood flows through the arteries in real time. Using sound waves, this test can detect narrowed or blocked arteries and measure the speed and direction of blood flow. It is a safe, non-invasive way for specialists to identify areas where circulation may be restricted.
CT Angiography (CTA)
Computed Tomographic Angiography uses advanced imaging and contrast dye to create highly detailed images of the arteries. This scan allows physicians to see exactly where plaque buildup or blockages are located and how severely the artery is narrowed. CTA can be especially helpful when planning treatment for more complex cases of PAD.
Magnetic Resonance Angiography (MRA)
Magnetic Resonance Angiography uses magnetic fields and radio waves to produce detailed images of blood vessels. Like CT angiography, this test helps physicians evaluate the structure of the arteries and locate areas where circulation is reduced.
Diagnostic Angiography
In some cases, physicians may recommend diagnostic angiography. During this procedure, a small catheter is inserted into the artery, and contrast dye is used to visualize blood flow on imaging. Angiography provides a precise view of the arteries and may be performed as part of a minimally invasive treatment procedure.
At the Vascular Institute of Michigan, these diagnostic tools help specialists quickly identify circulation problems and develop a personalized treatment plan to restore healthy blood flow and relieve PAD symptoms.
Treatment Options for Peripheral Artery Disease
Treatment for Peripheral Artery Disease depends on the severity of symptoms and the degree of arterial blockage. The primary goal is to restore healthy blood flow to the legs while preventing the disease from progressing. For many patients, treatment begins with lifestyle changes and medical management, but more advanced cases may require minimally invasive procedures or surgery.
A comprehensive treatment plan is designed to improve circulation, relieve symptoms, and reduce the risk of complications such as chronic wounds or limb-threatening circulation loss.
Lifestyle and Medical Management
In the early stages of PAD, physicians often recommend changes that improve overall vascular health and slow plaque buildup in the arteries. One of the most important steps is tobacco cessation, since smoking significantly accelerates artery damage and plaque formation.
Patients may also be prescribed medications to manage conditions that contribute to PAD, such as high blood pressure or high cholesterol. Blood-thinning medications are sometimes used to help prevent clot formation and improve circulation. These treatments can help control the disease and reduce the risk of further vascular complications.
While lifestyle and medication therapy can be effective in early stages, patients with more severe blockages or persistent symptoms may benefit from interventional treatment.
Interventional and Surgical PAD Treatments
When Peripheral Artery Disease significantly restricts blood flow, treatment may be recommended to restore circulation to the legs. At the Vascular Institute of Michigan, we offer both minimally invasive and surgical PAD treatment options that address blocked or narrowed arteries.
Depending on the severity and location of the blockage, treatment may involve opening the artery, removing plaque buildup, dissolving clots, or creating a new pathway for blood flow. These treatments are designed to restore circulation, relieve symptoms, and protect long-term limb health.
Angioplasty
Angioplasty is one of the most common treatments for PAD. During this procedure, a small balloon is guided into the narrowed artery and gently inflated. This widens the vessel and improves blood flow to the affected area.
Stenting
In some cases, a small metal mesh tube called a stent is placed inside the artery after angioplasty. The stent helps keep the artery open and supports healthy blood flow.
Atherectomy
Atherectomy is a specialized procedure that removes plaque buildup directly from the artery using a small catheter-based device. This technique is particularly helpful in arteries that have significant plaque or calcification.
Thrombolytic (TPA) Therapy
If a blood clot is contributing to the blockage, physicians may use thrombolytic therapy with a medication called tissue plasminogen activator (TPA). This medication helps dissolve clots and restore circulation to the affected artery.
Bypass Surgery
In more advanced cases where arteries are severely blocked, surgical bypass may be recommended. During this procedure, a surgeon creates a new pathway for blood flow around the blocked artery using a graft. This restores circulation to the lower leg and foot.
At the Vascular Institute of Michigan, specialists evaluate each patient carefully to determine the most appropriate treatment approach. By combining medical therapy, minimally invasive procedures, and surgical options when necessary, the goal is to restore circulation, relieve symptoms, and help patients regain mobility and quality of life.
Why Early Treatment Matters
Peripheral Artery Disease is more than a circulation problem in the legs. It can also signal widespread vascular disease affecting arteries throughout the body. As blood flow becomes restricted, patients may experience worsening leg pain, reduced mobility, and difficulty with everyday activities like walking.
If left untreated, PAD can lead to serious complications, including slow-healing wounds, infections, and an increased risk of heart attack or stroke. The good news is that early diagnosis and modern vascular treatments can restore blood flow, relieve symptoms, and help patients regain mobility and quality of life.
When to See a PAD Specialist
You should consider seeing a vascular specialist if you experience:
- Leg pain while walking that improves with rest
- Numbness or weakness in the legs
- Cold feet or toes
- Foot wounds that do not heal
- Sudden changes in walking ability
Early evaluation allows specialists to diagnose PAD before complications develop.

Frequently Asked Questions About Peripheral Artery Disease
Is PAD the same as poor circulation?
PAD is one of the most common causes of poor circulation in the legs. It occurs when plaque buildup narrows the arteries and reduces blood flow.
Can PAD be reversed?
Plaque buildup cannot always be fully reversed, but treatments and lifestyle changes can slow progression, improve blood flow, and reduce symptoms.
Is PAD dangerous?
Yes. PAD increases the risk of heart attack, stroke, and limb complications if left untreated. Early diagnosis significantly improves outcomes.
Are PAD procedures painful?
Most minimally invasive procedures are performed with local anesthesia and mild sedation. Patients typically experience minimal discomfort and recover quickly.
What Happens if PAD is Left Untreated?
If Peripheral Artery Disease (PAD) is left untreated, reduced blood flow to the legs can worsen over time. This may lead to increasing leg pain, difficulty walking, and slow-healing wounds on the feet or legs. In severe cases, poor circulation can cause tissue damage, infection, or even amputation. PAD is also linked to a higher risk of heart attack and stroke, which is why early diagnosis and treatment are important.
