Arterial Peripheral Vascular Disease
Peripheral arterial disease is a vascular condition that affects millions of people worldwide. Approximately 6.5 million people age 40 and older in the United States have PAD. Peripheral arterial disease is also commonly shortened to PAD or may be called peripherial vascular disease.
PAD is a condition in which narrowed arteries reduce blood flow to the arms or legs. This disease commonly affects the legs or lower extremities. It refers to the narrowing or blockage of the vessels that carry blood from the heart to the legs. Essentially, this condition results from plaque buildup due to atherosclerosis.
This page is for patients, caregivers, and anyone interested in vascular health. Understanding peripheral arterial disease is key because early detection and treatment can help slow its effects. Additionally, it can prevent gangrene, infections, and even limb amputation. By learning about symptoms, risk factors, diagnosis, and treatment options, you can take proactive steps to protect your vascular health and improve your quality of life.

What is Peripheral Arterial Disease?
Peripheral Arterial Disease (PAD) is a widespread circulatory problem that affects the arteries outside of the heart and brain. It is also sometimes referred to as peripheral vascular disease (PVD). PAD is a common condition in which narrowed arteries reduce blood flow to the arms or legs. In the legs or lower extremities, PAD refers to the narrowing or blockage of the vessels that carry blood from the heart to the legs.
This blocked or narrowed artery is often due to the buildup of fatty deposits known as atherosclerosis. This condition primarily affects arteries in the legs, making it harder for oxygen-rich blood to reach the muscles. The specific location of the affected artery influences the severity and type of symptoms, such as leg discomfort, rest pain, leg discolorations, sores that do not heal, and more.
When an artery narrows, blood flow decreases. This can lead to various complications affecting the legs and overall vascular health. Understanding PAD is crucial, as it’s a sign of more extensive, systemic arterial disease, which can increase the risk of heart attack and stroke.
PAD often goes unrecognized because early symptoms can be subtle. However, awareness and understanding can lead to earlier diagnosis and better management. Early detection is vital in preventing more serious health issues.
To diagnose PAD, healthcare providers typically rely on a combination of medical history, physical examinations, and specific tests. These tests may include the Ankle-Brachial Index (ABI), ultrasounds, and angiography. The ABI is a simple, non-invasive test that compares blood pressure in the ankle and arm.
Effective management of PAD involves lifestyle changes and medical treatments. These interventions aim to reduce symptoms, improve quality of life, and prevent complications. Lifestyle modifications, such as regular exercise and quitting smoking, play a critical role.
Understanding the underlying cause is important. This knowledge guides treatment and informs patients of the associated cardiovascular risks. By addressing these risks, individuals can better manage PAD and its potential complications.

The Impact of PAD on Vascular Health
PAD can start quietly but has a real impact on your vascular health over time. When circulation is reduced, your legs and feet may not get the blood supply they need — especially during walking or exercise. For some people, that shows up as cramping or heaviness in the legs. For others, it can mean slower healing and a higher chance of complications from small cuts or sores.
Because PAD is usually caused by plaque in the arteries, it can also be a sign of broader vascular disease. That’s why getting evaluated matters: treatment can improve circulation, help you stay active and lower the risk of more serious issues down the road.
Understanding the impact of PAD is the first step—next, let’s learn how to recognize its symptoms early.
Recognizing PAD Symptoms
PAD symptoms can look different from person to person and some people don’t notice anything at first. When symptoms do show up they’re often related to reduced blood flow to the legs and feet especially during activity.
Common signs and symptoms of PAD include:
- Leg pain, cramping, or tightness when walking that improves with rest (often in the calf, thigh or buttock)
- Heaviness, fatigue, or weakness in the legs during activity
- Numbness, tingling, or a “cold” feeling in the lower leg or foot
- One foot or leg feels cooler than the other
- Changes in skin color (pale, bluish, or darker tones) or shiny skin on the legs
- Slow-healing sores or wounds on the feet or toes
- Reduced hair growth on the legs or slower-growing toenails
- Pain in the feet or toes while resting, especially at night
- In men, erectile dysfunction can sometimes be linked to reduced blood flow
Who Is At Risk For PAD
Peripheral Arterial Disease is most often caused by plaque in the arteries, which reduces healthy blood flow to the legs and feet. While PAD can happen to anyone, certain health conditions and lifestyle factors can increase your risk.
Common risk factors for PAD include:
- Smoking (current or past) — one of the biggest risk factors for developing PAD* Diabetes — can damage blood vessels and plaque build up over time
- High blood pressure — puts extra pressure on the artery walls and accelerates vascular disease
- High cholesterol — contributes to plaque in the arteries
- Age (over 50) — risk increases as we get older
- Family history of vascular disease — PAD, heart disease or stroke
- Being overweight or inactive — worsens circulation and cardiovascular strain
- History of heart disease or stroke — PAD often occurs with other forms of vascular disease
If you have one or more of these risk factors it doesn’t mean you have PAD — but it does mean it’s smart to pay attention to symptoms and talk to a vascular specialist. Early detection can help you protect your circulation and lower the risk of more serious complications.
Diagnosing PAD
At Coastal Vascular Center, diagnosing Peripheral Arterial Disease (PAD) starts with understanding your symptoms and your circulation. PAD is caused by reduced blood flow through the arteries—most often due to plaque buildup—so our goal is to confirm whether blood flow is limited, identify where the narrowing occurs, and determine its severity.
What to Expect During a PAD Evaluation
1) Medical history and symptom review
We’ll talk through what you’re feeling and when it happens—especially leg pain or cramping with walking, numbness, coldness in the feet, or wounds that are slow to heal. We’ll also review risk factors like smoking history, diabetes, high blood pressure, and cholesterol.
2) Physical exam of the legs and feet
We examine the skin and soft tissue for color or temperature changes. We also check for sores or ulcers that are not healing normally.
3) Pulse and circulation checks
We check pulses at key points in the legs and feet (such as the femoral, popliteal, and dorsalis pedis pulses). A weaker pulse can be a sign of reduced blood flow.
4) Non-invasive vascular testing
When PAD is suspected, we often use non-invasive tests to measure circulation and pinpoint where the problem is. Depending on your symptoms, we may recommend:
- Ankle-Brachial Index (ABI): compares blood pressure in the ankle and the arm to screen for reduced blood flow
- Doppler ultrasound: uses sound waves to evaluate blood flow through the arteries
- Treadmill exercise testing: helps us understand how symptoms change with activity and how limited blood flow becomes during walking
- Segmental pressures: measure blood pressure at different levels of the leg to help locate narrowing or blockage
- Pulse Volume Recording (PVR): evaluates changes in blood volume in the legs to assess the severity of circulation problems
5) Advanced imaging (when needed)
If we need a more detailed view of the arteries—especially when planning treatment—we may recommend imaging such as Magnetic Resonance Angiography (MRA) to map blood vessels and identify significant narrowing or blockage.
6) Bloodwork to evaluate risk factors
We may also check vascular risk labs, such as cholesterol and blood glucose levels, to guide long-term management.
A thorough evaluation confirms the presence of PAD. It also assesses disease severity. This guides a treatment plan matched to your symptoms and goals. It also accounts for your overall vascular health.
Treatment Options For PAD
At Coastal Vascular Center, we treat Peripheral Arterial Disease (PAD) with one goal. We aim to improve circulation and protect your long-term vascular health. Treatment isn’t one-size-fits-all. We assess your symptoms, circulation, and key risk factors. These include smoking, diabetes, cholesterol, and blood pressure. We then create a plan to improve current symptoms. We also aim to reduce future complications.
Lifestyle Changes (the foundation of treatment)
For many patients, the most effective first step is improving how the body uses blood flow and oxygen—especially in the legs. A structured walking program is among the most well-proven treatments for PAD because it can increase walking distance and reduce leg pain over time.
Key lifestyle strategies we often recommend include:
- Supervised or structured exercise therapy to improve endurance and circulation
- Smoking cessation (if you smoke), because tobacco significantly worsens artery disease
- Heart-healthy nutrition, such as a Mediterranean-style or DASH approach
- Foot care, especially if you have diabetes or reduced sensation, to help prevent wounds and infections
Medications (to reduce risk and support blood flow)
Medications can play an important role in PAD care—both for symptom relief and for reducing the risk of serious cardiovascular events. Depending on your health history, we may prescribe medications to:
- Lower the risk of blood clots (often with antiplatelet therapy such as aspirin or similar medications)
- Manage cholesterol (commonly with statins) to slow plaque buildup
- Control blood pressure and blood sugar, when needed, to protect the arteries
- Improve walking symptoms in select patients to reduce claudication discomfort
We also monitor your response and adjust your plan over time—PAD management works best when it’s actively followed and fine-tuned.
Minimally Invasive Procedures and Surgery (when circulation is significantly reduced)
If symptoms are limiting your daily life, if circulation is severely reduced, or if there are non-healing wounds, we may recommend a procedure to restore blood flow. Options may include:
- Angioplasty and stenting to open narrowed arteries and help keep them open
- Atherectomy to remove plaque from inside the artery in appropriate cases
- Bypass surgery to reroute blood flow around a blocked segment when needed
If a procedure is recommended, we’ll walk you through what we see on your imaging, why we’re recommending that approach, and what recovery looks like—so you can make an informed decision.
Follow-Up and Surveillance (protecting results long-term)
PAD is a chronic condition, which means ongoing follow-up matters. After treatment, we continue to monitor your circulation, symptoms, and risk factors. Regular surveillance helps us:
- Track improvement in blood flow and walking ability
- Catch new narrowing early (before it becomes a bigger problem)
- Reduce the risk of limb-threatening complications and cardiovascular events
At Coastal Vascular Center, PAD care is a partnership. With the right plan—and the right follow-through—many patients can stay active, reduce symptoms, and protect their vascular health long-term.

Living With PAD
Living with Peripheral Arterial Disease (PAD) means making a few adjustments—without giving up the things you love. At Coastal Vascular Center, we help you focus on what matters most: staying active, protecting your circulation, and reducing your risk of future complications. With the right plan and follow-through, many people with PAD can live full, independent lives.
Daily Habits
Here are a few habits that make a difference:
- Pay attention to your legs and feet. Check for new sores, color changes, swelling, or skin breakdown—especially if you have diabetes or reduced sensation.
- Wear supportive shoes. Comfortable shoes and clean, dry socks help prevent small injuries that can turn into bigger problems when circulation is limited.
- Keep moving—but pace yourself. Walking is one of the best tools for PAD, but you need to build gradually and listen to your body.
- Stay on top of your risk factors. Blood pressure, cholesterol, blood sugar, and smoking status all impact vascular health.
- Tell us. If symptoms change, pain gets worse, or a wound isn’t healing, we want to know sooner rather than later.
PAD can also take a mental toll. If you’re feeling frustrated, anxious, or discouraged, you’re not alone—and support from family, friends, and your care team can make this process much more manageable.
Managing Symptoms
Symptom management is a big part of living well with PAD. The goal isn’t to “tough it out,” it’s to improve circulation safely, reduce pain, and help you stay active with confidence.
What Works for Most Patients
- Follow a structured walking plan. Many patients do best with intervals: walk until symptoms start, rest until they improve, then repeat. Over time, this can improve endurance and reduce claudication.
- Build a routine you can stick to. Consistency matters more than intensity. Small improvements add up.
- Use stress reduction tools. Chronic symptoms can wear you down. Simple practices like deep breathing, gentle stretching, and good sleep habits can help.
- Keep doing what you enjoy. Hobbies and social time aren’t “extra”—they’re part of staying well and motivated.* Don’t wait to get help. New rest pain, worsening symptoms or non-healing sores should be evaluated right away.
If you’re not sure if what you’re feeling is “normal PAD discomfort” or something more serious we can help you figure that out.
Start Your Fight Against PAD
PAD is a serious circulation condition, but it’s also treatable—especially if caught early. If you’re experiencing leg pain with walking, numbness or tingling in the feet, or wounds that won’t heal, it’s worth getting evaluated. PAD should not be self-diagnosed, and delaying care can increase the risk of complications, including heart attack, stroke, and in severe cases, limb-threatening circulation problems.
At Coastal Vascular Center, Dr. Ayar and our team take a comprehensive approach to PAD. We use advanced diagnostic tests to assess your arteries and identify the cause of your symptoms. We then tailor a treatment plan to your symptoms, medical history, and health goals.

Do You Have Questions?
What is Peripheral Artery Disease?
Peripheral artery disease (PAD) is a condition where a blocked artery or a blocked or narrowed artery reduces blood flow in the large arteries of the body. This often happens because of atherosclerosis, which is the buildup of plaque in the arteries. This causes less blood flow to the limbs, especially the legs. Leg discomfort when active is often the first symptom of PAD. This can lead to pain, cramping, and numbness during physical activity.
What Are the Common Symptoms of PAD?
Symptoms of PAD vary but typically include:
-
Leg pain or cramping during walking or exercise, especially in the calf muscles, which subsides with rest (known as intermittent claudication).
-
Numbness or weakness in the legs.
-
Cold sensations in the lower extremities.
-
Non-healing wounds or ulcers on the feet or legs.
-
Shiny skin or other skin changes, such as thin or brittle skin on the legs and feet.
-
Erectile dysfunction in men, due to reduced blood flow.
-
Severe pain in the legs or feet, especially at rest, which may indicate advanced disease.
In severe cases, PAD can lead to critical limb ischemia, where tissues may sustain damage due to lack of blood flow and may present as severe rest pain in the legs or feet.
A healthy lifestyle is the best way to prevent leg pain due to peripheral artery disease (PAD).
What Are the Risk Factors for PAD?
Risk factors for PAD include:
-
Smoking, which damages arteries and increases plaque formation.
-
Diabetes affects blood flow in the peripheral arteries and significantly increases the risk of developing PAD.
-
High cholesterol, high blood cholesterol, and high blood pressure.
-
Elevated blood cholesterol levels contribute to atherosclerosis and increase PAD risk.
-
Coronary artery disease is a common comorbidity and shares risk factors with PAD, such as atherosclerosis and plaque buildup.
-
A sedentary lifestyle or lack of physical activity.
-
Being over the age of 50.
-
Family history of heart disease increases the risk of developing PAD.
-
Men are at a higher risk for PAD compared to women, and postmenopausal women have an increased risk.
-
Other risk factors include uncontrolled blood pressure, diabetes, and cholesterol.
Controlling high blood pressure, high cholesterol, and diabetes is important for preventing PAD, and these steps are central to slowing or partially reversing PAD progression.
What Causes Peripheral Artery Disease?
PAD may sound like a debilitating and scary condition, but there are some simple solutions. Atherosclerosis causes peripheral arterial disease. This is the gradual buildup of fatty material in your arteries that leads to plaque buildup and impaired blood flow throughout your body. Out-patient interventional radiology can remove this material from around artery walls to restore proper blood circulation back to areas such as the legs or feet.
To help prevent PAD, it is important to eat healthy foods and quit smoking, as both steps can reduce your risk and help maintain better vascular health.
How Is PAD Diagnosed?
PAD is diagnosed using relatively simple tests:
-
Physical exam: Your healthcare provider will assess your blood flow and arterial health by checking pulses, blood pressure, and performing specific vascular tests.
-
Ankle-Brachial Index (ABI): Compares the blood pressure in your ankle to that in your arm, highlighting abnormal blood flow.
-
Ultrasound imaging: Ensures visuals of blood flow through the arteries.
-
Angiography: Provides detailed images of narrowed arteries.
-
Magnetic resonance angiography (MRA): An advanced, noninvasive imaging method that uses a large magnet, radio waves, and contrast dye to produce detailed images of blood vessels and tissues, helping to visualize blood flow and detect blockages without invasive procedures.
Your doctor may also screen you for risk factors in your medical history.
When Should I See a Doctor About PAD?
If you have symptoms of PAD or fall into a higher-risk group, we recommend that you come in for an evaluation. In its advanced form, patients with PAD may suffer from non-healing wounds, which can increase the chance of infection and amputation. After an amputation, there is a 5-year mortality rate of 50%. However, HALF OF THE AMPUTATIONS CAN BE PREVENTED BY EARLY DETECTION, WHICH IS CRITICAL AND LIFESAVING IN SOME CASES!

What Are the Treatment Options for PAD?
Effective management of arterial peripheral vascular disease (PAD) focuses on improving blood flow, preventing disease progression, and enhancing the patient’s quality of life. Common treatments include:
- Lifestyle changes: Quitting smoking, adopting a healthy diet, engaging in regular physical activity, and limiting or quitting alcohol intake to help prevent PAD.
- Medical treatment: Medications such as blood thinners (antiplatelet medications) are used to prevent blood clots, along with drugs to lower cholesterol and manage blood pressure.
- Minimally invasive procedures: Angioplasty or stenting are performed to open up blocked or narrowed arteries, increase blood flow, and prevent further disease progression.
- Vascular surgery: In severe cases, vascular surgery such as bypass grafting may be necessary to reroute blood flow around a blocked or narrowed artery, while minimally invasive options like angioplasty and stent placement to open blocked arteries can also significantly improve circulation.
By addressing these questions, individuals can better understand PAD, its diagnosis, and options for treatment. If you suspect you have PAD, speak with a vascular specialist for proper evaluation and guidance.
