· The typical presentation of intermittent claudication is lower extremity pain during ambulation that is relieved with rest. The progression of symptoms is gradual. The pain may be localized to the buttocks or the lower leg, depending on the site of occlusion. Patients with aortoiliac disease frequently develop buttock pain.
When should you go to the ER for peripheral vascular disease?
New or worsening fatigue, weakness, or shortness of breath. “Those may have hopefully made you better, but if you suddenly notice a deterioration of your symptoms -- you can't walk, you're in pain -- seek emergency care. Arteries may be able to be reopened or at the very least you may need blood thinners.”
Does claudication require surgery?
Both minimally-invasive treatments such as angioplasty or stenting, and traditional procedures such as bypass surgery have important roles. Minimally invasive endovascular treatments may be recommended if the claudication becomes severe enough to interfere with the patient's lifestyle and improvement seems likely.
Should you walk through claudication pain?
It is good to push through your claudication pain, but if you are getting significant pain elsewhere, for example in joints or your chest, please see your GP and discuss your concerns.
What happens if claudication is not treated?
Claudication can lead to a cycle that results in worsening cardiovascular health. Pain may make exercise intolerable, and a lack of exercise results in poorer health. Peripheral artery disease is a sign of poor cardiovascular health and an increased risk of heart attack and stroke.
How serious is claudication?
Over time, you may no longer be able to walk because the pain is so severe. Claudication is linked to health conditions that also increase your risk for heart attack or stroke. So you should be checked and possibly treated for artery disease in other parts of the body.

How far can you walk with claudication?
Imparato et al. (1975) classified "mild claudication" as the ability to walk 2 to 3 blocks (900 feet) before stopping; "moderate claudication," 1 or 2 blocks (600 feet); and "severe claudication," less than 1 block (300 feet).
Should you walk with intermittent claudication?
walking should be performed as interval training (walk-rest-walk) at moderate-to-maximum claudication. duration of exercise should be at least 30-45 minutes per session, at least three times a week for at least 12 weeks. warm-up and cool-down periods should be a part of every session.
Can PAD make you unable to walk?
Pain caused by PAD is characterized by the inability to walk due to muscle pain after walking a certain distance, but being able to resume walking after resting for a while. Consult your doctor if you display symptoms of high blood pressure or diabetes, especially if you are prone to arteriosclerosis.
How long can you live with claudication?
Patients with intermittent claudication carry a high risk for cardiovascular complications. The TransAtlantic Inter-Society Consensus (TASC) Group estimated a five-year overall mortality of 30% for these patients, the majority dying from cardiovascular causes.

Claudication is a symptom of a narrowing or blockage of an artery. Typical symptoms of claudication include: Pain, a burning feeling, or a tired feeling in the legs and buttocks when you walk. Pain when you are resting is a sign that your blocked arteries have become worse.
How to tell if you have claudication?
Typical symptoms of claudication include: Pain, a burning feeling, or a tired feeling in the legs and buttocks when you walk. Shiny, hairless, blotchy foot skin that may get sores. The leg is pale when raised (elevated) and red when lowered. Cold feet.
Why does claudication hurt when walking?
Claudication is pain in your thigh, calf, or buttocks that happens when you walk. It can make you limp. It may be a symptom of peripheral artery disease (PAD). This is when narrowed or blocked arteries reduce the blood flow to your legs. At first, claudication pain occurs when you walk a certain distance and goes away when you rest.
What causes claudication in the legs?
What causes claudication? Peripheral artery disease (PAD) is very common, mainly in people over age 50. PAD is caused by narrowed or blocked arteries in the legs or in the body’s main artery (the aorta). This can reduce blood flow to muscles in your calf, thigh, or buttocks.
What does it mean when your legs are pale?
Pain, a burning feeling, or a tired feeling in the legs and buttocks when you walk. Shiny, hairless, blotchy foot skin that may get sores. The leg is pale when raised (elevated) and red when lowered. Cold feet. Impotence in men.
What is contrast dye?
A thin, flexible tube is put into a leg artery. A contrast dye is injected into the artery. The contrast dye makes the arteries and veins show up clearly on the X-ray.
What are some ways to treat high blood pressure?
Treating related health problems, such as high cholesterol, high blood pressure, or high blood sugar levels. This may involve changes in diet, exercise, or medicine. Taking medicines that help prevent blood clots, such as aspirin or other medicines. Taking medicines that may improve walking distances in some cases.
How to treat claudication?
Treatment for claudication usually focuses on the reduction of risk factors associated with atherosclerosis: Smoking cessation. Walking, usually 30 minutes a day. Medication and lifestyle changes aimed at reducing cholesterol, blood pressure and blood-sugar levels.
What are the symptoms of claudication?
PAD symptoms may include: Pain in the buttocks, thigh and/or calf, occurring with walking. Tired or burning sensation in the buttocks, thigh and/or calf with walking.
What is claudication in the thigh?
What is claudication? Claudication refers to the pain, aching or fatigue of the muscles of the buttocks, thigh and/or calf that occurs with exertion. This pain or cramping is caused by poor circulation due to blockage of the arteries of the lower extremity. Nearly 9 million people, or 12 percent of the U.S.
What is CT angiography?
CT angiography: An advanced X-ray procedure that uses a computer to generate three-dimensional images of blood vessels. Magnetic resonance angiography (MR angiography): The patient is exposed to radiofrequency waves in a strong magnetic field.
What is self expanding stent?
Self-expanding: Compressed stents are delivered to the diseased site. They expand upon release and are left in place to hold open the artery. These stents are more flexible. Laser atherectomy: Small bits of plaque are vaporized by the tip of a laser probe.
What is the procedure to remove plaque from the artery?
Laser atherectomy: Small bits of plaque are vaporized by the tip of a laser probe. Directional atherectomy: A catheter with a rotating cutting blade is used to physically remove plaque from the artery, opening the flow channel.
How is a balloon inflated?
The balloon is inflated using a saline solution one or more times to expand the narrowed or occluded artery . Cutting balloon: A balloon imbedded with micro-blades is used to dilate the diseased area. The blades cut the surface of the plaque, reducing the force necessary to dilate the vessel.
What is the treatment for intermittent claudication?
Patients with intermittent claudication should receive conservative treatment . Aggressive risk factor modification, smoking cessation, antiplatelet therapy and a walking program are essential. In addition, medical treatment of the symptoms of claudication may benefit some patients.
How does walking help with claudication?
Walking improves the symptoms of claudication in several ways. The muscle can better adapt to anaerobic metabolism with repeated exposure to an ischemic environment. Oxidative metabolism and the overall number of available mitochondria increase. A meta-analysis 21 showed an increase of 179 percent in the initial claudication distance and 122 percent in the absolute claudication distance in patients who followed a walking program. Five components of a successful program were also identified. Walking is the preferred mode of exercise. Patients should walk at least three times per week for at least 30 minutes at each session. Near-maximal claudication pain (absolute claudication distance) should be the resting point, and the patients should follow the program for at least six months. 21 A supervised program is superior to a home-based exercise program. 22 A walking program can increase the objective distance that the patient with claudication can ambulate. This may result in subjective improvement and lead to an enhanced quality of life.
What percentage of people with peripheral arterial occlusive disease are over 70?
Peripheral arterial occlusive disease occurs in about 18 percent of persons over 70 years of age. Usually, patients who have this disease present with intermittent claudication with pain in the calf, thigh or buttock that is elicited by exertion and relieved with a few minutes of rest. The disease may also present in a subacute or acute fashion.
Where are blood pressure cuffs placed?
Blood pressure cuffs are placed on the proximal and distal thigh, below the knee and above the ankle. The proximal lower extremity pressures should be equal to or greater than the upper extremity pressures, and the drop in Doppler pressure between segments no greater than 20 mm Hg.
How to calculate ankle brachial index?
The ankle-brachial index is calculated by dividing the ankle pressure (the higher of the posterior tibial artery pressures) by the brachial systolic pressure (the higher of the two arm pressures).
Development and Progression
In the early stages of PAD, patients may experience cramping or fatigue in the legs or buttocks while walking or exercising. This is referred to as "intermittent claudication." Claudication may occur in one or both legs, depending on where the blockage is. The pain, or other symptoms subside when the activity is stopped.
Symptoms
Pain in the buttocks, thigh, or calf while walking that resolves at rest
Diagnosis
Auscultation - The presence of a bruit (“whooshing” sound), in the arteries of the legs, confirmed using a stethoscope.
Endovascular Procedures
For most people with PAD, symptoms may be mild or absent, and no treatment of the artery blockages is required. However as these blockages become more extensive, patients may experience pain and disability that limits their walking, and in the most advanced cases, individuals may be at risk for loss of the limb unless circulation is improved.
Lower Extremity Bypass Surgery
For patients who are not good candidates for angioplasty, or who have already failed a prior angioplasty attempt, lower extremity bypass surgery is a well-established and highly effective procedure.
