Overview

Furnishings of atherosclerosis on leg arteries.

What is peripheral arterial disease (PAD)?

Peripheral arterial disease (PAD), also known equally peripheral vascular illness or peripheral artery disease, is plaque buildup in your leg arteries that carry oxygen and nutrient-rich blood from your heart to your arms and legs.

Shaped like hollow tubes, arteries have a smooth lining that prevents blood from clotting and promotes steady blood flow. When you take peripheral artery disease, plaque (made of fat, cholesterol and other substances) that forms gradually inside your avenue walls slowly narrows your arteries. This plaque is also known as atherosclerosis.

Many plaque deposits are hard on the outside and soft on the inside. The hard surface can crack or tear, allowing platelets (disc-shaped particles in your blood that help it clot) to come to the area. Claret clots can form around the plaque, making your artery fifty-fifty narrower.

If your arteries become narrowed or blocked with plaque or a blood clot, blood tin't get through to nourish organs and other tissues. This causes damage ― and eventually death (gangrene) ― to the tissues below the blockage. This almost often occurs in your toes and feet.

The charge per unit at which PAD progresses varies with each person and depends on many factors, including where in your body the plaque forms and your overall health.

What are the risk factors for peripheral arterial disease?

Smoking is the virtually of import chance factor for PAD. In fact, eighty% of people with PAD are people who currently or were sometime smokers.

Regardless of your sexual practice, you're at run a risk of developing peripheral arterial disease when you have i or more than of these gamble factors:

• Using tobacco products (the most stiff risk factor).
• Having diabetes.
• Being age 50 and older.
• Existence African-American.
• Having a personal or family history of heart or claret vessel disease.
• Having high blood pressure (hypertension).
• Having high cholesterol (hyperlipidemia).
• Having abdominal obesity.
• Having a blood clotting disorder.
• Having kidney disease (both a take a chance factor and a effect of PAD).

Although PAD is a different condition from coronary artery disease, the two are related. People who have ane are likely to have the other. The U.South. National Institutes of Health estimates that a person with PAD has a six to seven times higher chance of coronary avenue illness, heart attack, stroke or a transient ischemic attack (mini-stroke) than the general population. A person with middle disease has a ane in 3 chance of having peripheral artery disease in the legs.

Non surprisingly, the 2 diseases also share some common run a risk factors. This is considering these risk factors cause the same changes in arteries in your arms and legs as they do in your coronary arteries.

Equally in coronary artery disease, many of these risk factors are out of your command. But, according to researchers, tobacco employ is the single nigh important modifiable (child-bearing) risk gene for PAD and its complications. Tobacco utilise increases the run a risk for PAD by 400% and brings on PAD symptoms nearly ten years before. Compared with non-smokers of the same age, smokers with PAD are more than likely to die of eye set on or stroke, have poorer results with middle bypass surgery procedures on their legs and are twice equally likely to take a limb amputation.

How common is this condition?

PAD is common, affecting betwixt eight and 12 million Americans. Despite the prevalence of PAD, information technology's surprisingly underdiagnosed and undertreated.

How does this condition impact my body?

The typical symptom of PAD is chosen "claudication," a medical term that refers to pain in your leg that comes on with walking or practise and goes away with remainder. The pain occurs because your leg muscles aren't getting plenty oxygen.

The dangers of PAD extend well beyond difficulties in walking, and the consequences can be far worse than missing a shopping trip or golf. Peripheral avenue illness increases the risk of developing a not-healing sore of the legs or feet. In cases of severe PAD, these sores tin can develop into areas of expressionless tissue (gangrene) that ultimately make it necessary to amputate your foot or leg.

Considering your body's circulatory arrangement is interconnected, the furnishings of PAD tin extend beyond the afflicted limb. People with atherosclerosis of their legs normally have information technology in other parts of their bodies. People who have peripheral artery disease are at increased take a chance for having a heart set on, stroke, transient ischemic assault (mini-stroke) or problems with their kidney (renal) arteries.

If left untreated, people with PAD can develop serious health issues, including:

• Heart assault: Permanent damage to your heart musculus caused by a lack of blood supply to your heart for an extended time.
• Stroke: Interruption of the blood flow to your brain.
• Transient ischemic set on (TIA): A temporary intermission in the blood supply to your brain.
• Renal artery illness or stenosis: A narrowing or blockage of the artery that supplies claret to your kidney.
• Amputation: The removal of part or all of your foot or leg (rarely your arm), specially in people who besides take diabetes.

Symptoms and Causes

What are the symptoms of PAD?

One-half of the people who have peripheral vascular disease don't have whatever symptoms, simply pain or discomfort in their legs is a common symptom. You may besides feel weak or tired while walking. Affected parts of your leg may include your calves, thighs or buttocks.

PAD can build up over a lifetime, and the symptoms may not become obvious until afterwards in life. For many people, the outward symptoms won't appear until their artery has narrowed by 60% or more.

Early symptoms

The outset noticeable symptom of PAD may exist intermittent claudication ― leg discomfort, pain or cramping that:

• Develops with action.
• Goes away with rest.
• Comes dorsum when you resume activity.

You may notice the hurting in your dogie, but you may also feel it in your buttocks or thighs. With intermittent claudication, your leg muscles may feel:

• Numb.
• Weak.
• Heavy.
• Tired.

The pain can exist severe enough to limit your ability to participate in activities you enjoy, such as golfing or chasing after grandchildren.

Reduced blood catamenia to your leg muscles causes this type of cyclical hurting, which goes abroad at residual because your muscles demand less blood period at rest.

Advanced symptoms

Symptoms of advanced PAD may include:

• A burning or agonized pain in your anxiety and toes while resting, especially at night while lying flat.
• Cool skin on your feet.
• Redness or other color changes of your skin.
• More than frequent infections.
• Toe and foot sores that don't heal.

What causes PAD?

Atherosclerosis that develops in the arteries of your legs — or, less commonly, your arms — causes peripheral arterial disease. Like atherosclerosis in your heart (coronary) arteries, an aggregating of fatty plaque in your blood vessel walls causes peripheral vascular affliction. As plaque builds upwardly, your blood vessels go narrower and narrower, until they get blocked.

Diagnosis and Tests

How is PAD detected?

Talk to your doctor if you're having symptoms of PAD so the cause of your symptoms can exist identified and treatment tin be initiated every bit before long as possible. Early detection of PAD is of import so the right treatments can be provided before the affliction becomes severe plenty to atomic number 82 to complications, such every bit heart attack or stroke.

A physical exam will be performed and your medical history and take chances factors will exist reviewed. Your md may guild certain tests to help diagnose PAD and determine the severity of the disease.

• The ankle/brachial index (ABI) is a measurement of the claret pressure in your lower legs compared to the claret pressure level in your arms. During this test, blood pressure cuffs are placed on your arms and legs. The cuffs are inflated, while a paw-held device (called a Doppler) is used to listen to your blood menses. The ABI screening helps evaluate the amount of blood flow to your legs and feet, which is decreased in a person who has PAD. ABI is a highly accurate method for detecting PAD.
• A pulse book recording (PVR) is a noninvasive test that measures the blood volume changes that occur in your legs. During this examination, a blood pressure cuff is placed on your arm and multiple cuffs are placed on your legs. The cuffs are inflated slightly while yous're lying down. As blood pulses through your arteries, the blood vessels expand, causing an increment or decrease in the book of air inside the gage. A recording device displays these pulse volume changes equally a waveform on a monitor. Claret pressures are measured before and after exercise on a treadmill and help define if your pain is due to PAD or other causes. The PVR test also helps locate the area of blockages in your legs.
• A vascular ultrasound is a noninvasive examination used to examine blood circulation. During a vascular ultrasound, a transducer (small hand- held device) is placed on your skin over the artery to be examined. The transducer emits sound waves that bounce off your artery. These sound waves are recorded, and an image of the vessel is created and displayed on a monitor. This test may exist used to notice a blockage in your artery.

Management and Handling

How is PAD treated?

The two main goals in the handling of PAD include:

• Reducing the risk of heart attack and stroke.
• Improving quality of life by easing the pain that occurs with walking.

With early on diagnosis, lifestyle changes and treatment, you tin cease PAD from getting worse. In fact, some studies have shown that you tin can reverse peripheral vascular disease symptoms with exercise combined with careful command of cholesterol and claret pressure. If yous think you're at risk for PAD or may already have the disease, talk to your primary intendance doctor, vascular medicine specialist or cardiologist and then yous can get started on a prevention or treatment program as soon every bit possible.

Lifestyle changes, medications and interventional procedures tin treat your PAD.

Lifestyle changes

Initial treatment of PAD includes making lifestyle changes to reduce your take a chance factors. Changes you lot can brand to manage your condition include:

• Quit using tobacco products. Enquire your healthcare provider about smoking cessation programs bachelor in your community.
• Eat a balanced diet that'due south high in cobweb and depression in cholesterol, fat and sodium. Limit fat to thirty% of your total daily calories. Saturated fat should account for no more than seven% of your total calories. Avert trans fats, including products made with partially hydrogenated and hydrogenated vegetable oils. If yous're overweight, losing weight will help you lower your full cholesterol and raise your HDL (skilful) cholesterol. A registered dietitian can assistance you lot brand the right dietary changes.
• Exercise. Begin a regular do plan, such equally walking. Walking is very of import and tin aid in the treatment of PAD. People who walk regularly can await a definite comeback in the distance they're able to walk before experiencing leg hurting.
• Manage other wellness conditions, such as high blood force per unit area, diabetes or high cholesterol.
• Continue your stress level depression. Exercise, yoga and meditation may help with this.
• Do adept foot and peel care to foreclose infection and reduce the risk of complications.

Medications

Medicines tin help you with conditions such every bit high blood pressure (antihypertensive medications), loftier cholesterol (statin medications) and diabetes. These drugs care for the take a chance factors of PAD and decrease your risk of stroke and middle attack.

An antiplatelet medication such as aspirin or clopidogrel may reduce the risk of heart set on and stroke.

Your healthcare provider may prescribe cilostazol to meliorate your walking distance. This medication helps people with intermittent claudication exercise longer earlier they develop leg pain. However, not everyone is eligible to have this medication. Your healthcare provider will tell you lot if y'all are.

Supervised exercise programs

A supervised exercise program will meliorate the symptoms of pain in your legs with walking (claudication), allowing you to walk farther. A structured plan typically includes walking on a treadmill in a supervised setting at least iii times per week.

People with PAD should as well walk at home for a full of at least 30 to 60 minutes every twenty-four hour period. The usual prescription is chosen "Start/Stop" exercise:

1. Walk until the discomfort reaches a moderate level and then finish.
2. Wait until the discomfort goes away completely.
3. Start walking over again.

For some people with more severe PAD, the claudication symptoms may still cause bug in daily life, even subsequently a few months of practise and medications. In more severe cases, restoration of blood period is necessary to relieve hurting at rest or to heal a wound. To restore blood menstruation, the get-go stride is usually an angiogram. A healthcare provider who specializes in invasive vascular procedures tin can do this.

Minimally invasive or surgical treatments

More advanced PAD that's causing severe hurting and limited mobility may require endovascular (minimally invasive) or surgical treatment. Some heart disease treatments also treat peripheral artery disease. Treatments include:

• Airship angioplasty : In this process, your healthcare provider passes a miniature airship through a catheter into your arteries. As the balloon expands inside of your artery, it pushes confronting the plaque and opens up space inside of your avenue.
• Stents: These are tiny metal support coils that your healthcare provider inserts into your arteries through a small opening using catheters (long, sparse tubes). Once they're in place, stents aggrandize against the inner claret vessel wall to support information technology and hold it open.
• Peripheral artery bypass surgery : Similar to a centre bypass, a surgeon uses a section of your salubrious vein or a constructed replacement to create a bypass for blood catamenia around the blocked area in your leg artery. This is usually reserved for the well-nigh severe PAD.
• Atherectomy : Your healthcare provider uses a catheter with a blade at the end to remove plaque buildup in your blood vessel.

Complications of PAD treatment

You should contact your healthcare provider if you have these issues afterward your procedure. They could be signs of an infection or other complications.

• Swelling, bleeding or pain where the catheter went into your pare.
• Breast pain.
• Shortness of jiff.
• Fever or chills.
• Dizziness.
• Swelling in your legs.
• Belly pain.
• An incision that's coming open up.

How long does it take to recover from this handling?

Yous may take soreness for a few days where your healthcare provider had to cut into your skin. It can take half-dozen to viii weeks to recover completely from the surgery. You lot may only need a few days to recover from your atherectomy.

Prevention

How can I prevent PAD?

Being aware that you take take chances factors for PAD may motivate you to take action to forestall PAD from developing. The same advice for maintaining a good for you heart applies to maintaining healthy circulation overall:

• Manage your weight.
• Swallow a low-fat, depression-sugar diet that includes at least five servings of fresh fruits and vegetables every day.
• Don't apply tobacco products.
• With your doctor'southward approval, do for at least 30 minutes a day on most days of the week.

If you lot have centre disease, you should discuss your run a risk factors for PAD with your healthcare provider and report any symptoms yous're having, such as pain, weakness or numbness in your legs.

Outlook / Prognosis

What tin can I expect if I have this condition?

Similar almost health conditions, PAD is more treatable when your healthcare provider finds information technology early. Peripheral vascular disease progresses at different rates depending on many factors, including where the plaque formed in your trunk and your overall health.

Outlook for this condition

Peripheral artery disease is a condition yous'll accept for the rest of your life. Although there'south no cure for PAD, it'south treatable. You can aid keep peripheral vascular disease from progressing in several means:

• Not using tobacco products.
• Exercising regularly.
• Limiting fat and following a healthy diet.
• Managing your gamble factors — such as diabetes, high cholesterol and high blood force per unit area.

Living With

How exercise I take care of myself?

It's very important that y'all take especially adept care of your feet to prevent non-healing sores. Foot intendance for people who accept PAD includes:

• Wearing comfy, appropriately plumbing equipment shoes.
• Inspecting your legs and feet daily for blisters, cuts, cracks, scratches or sores. Besides check for redness, increased warmth, ingrown toenails, corns and calluses.
• Not waiting to care for a small foot or skin problem.
• Keeping your feet clean and well moisturized. (Don't moisturize an area with an open sore.)
• Cutting your toenails after bathing, when they're soft. Cut them straight beyond and smooth them with a nail file.

In some cases, your healthcare provider may refer you to a podiatrist (foot skilful) for specialized foot care ― especially if y'all have diabetes. A podiatrist can help you with corns, calluses or other foot issues.

When should I see my healthcare provider?

Contact your healthcare provider if you:

• Go a bad infection in a sore on your foot. The infection can expand into your muscles, tissues, blood and bone. If your infection is severe, you lot may need to become to the hospital.
• Tin't walk effectually enough to do day-to-day activities.
• Have hurting in your legs when you're resting. This is a sign of poor blood menses.

When should I go to the ER?

Become immediate assist if yous can't experience or move your human foot or if it looks different from your other foot'southward skin color. This means you've lost blood flow to your leg without alarm.

What questions should I ask my medico?

• Do I demand medications to reduce my risk of PAD?
• How far should I walk when I commencement a walking program?
• Practice I demand surgical procedures for peripheral vascular disease?

A note from Cleveland Clinic

You have the ability to prevent PAD or go along it from getting worse by making lifestyle changes. Keep all of your follow-upward appointments with your healthcare provider and vascular specialist, and take the medicines they prescribe for all of your conditions. Knowing the alarm signs of PAD complications helps you know when to ask for help, too.
