The symptoms of claudication can be mimicked by many other conditions which cause pain in the legs such as arthritis and nerve problems (neuropathy).\u00a0 Neurogenic claudication is pain in the legs due to compression of nerves in the spinal cord and can be very difficult to distinguish from claudication due to arterial problems.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How common is intermittent claudication?&#8221; tab_id=&#8221;1759014806183-f54d1997-de0b20d4-347b&#8221;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">How common is intermittent claudication?<\/h2>\n<p>The Edinburgh Artery study (<a href=\"http:\/\/ije.oxfordjournals.org\/content\/25\/6\/1172.full.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Leng GC et al 1995<\/a>) examined this question.\u00a0 About 4 out of every 100 (4%) people over the age of 55 years experienced symptoms, but there was evidence of hardening of the arteries in a further 25% of patients who were not experiencing symptoms.\u00a0 In general PVD is commoner in men.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Why does PVD cause pain in the legs?&#8221; tab_id=&#8221;1759014827533-6ef99622-00a920d4-347b&#8221;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">Why does PVD cause pain in the legs?<\/h2>\n<p>Pain develops because there is a narrowing or blockage in the main artery taking blood to the leg due to hardening of the arteries (atherosclerosis). Over the years cholesterol and calcium build up inside the arteries. This occurs much earlier in people who smoke and those who have diabetes or high levels of cholesterol in the blood. The blockage in the arteries means that the blood flow is reduced. At rest there is enough oxygen in the blood reaching the muscles to prevent any symptoms.\u00a0 When walking the calf muscles need more oxygen, but because the blood flow is restricted the muscles cannot obtain enough oxygen from the blood and cramp occurs. This is made better by resting for a few minutes. If greater demands are made on the muscles, such as walking uphill, the pain comes on more quickly.\u00a0 Many patients also notice that if they are carrying heavy bags the pain comes on sooner because the leg muscles are having to work harder. Walking in bare feet or very flat shoes also tends to make the symptoms worse. Intermittent claudication is a manifestation of chronic (longstanding) peripheral vascular disease which has usually taken many years to develop. In some patients the blood flow to the legs can be so restricted that there is barely sufficient oxygen reaching the tissues even while resting.\u00a0 In these patients severe pain can develop particularly at night and it is only eased when the leg is dangled down over the edge of the bed.\u00a0 When this happens and tests show reduced blood flow, then critical limb ischaemia has developed and the leg is at risk of amputation.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;What are the signs of PVD in the legs?&#8221; tab_id=&#8221;1759014855534-cd1bf395-e35520d4-347b&#8221;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">What are the signs of PVD in the legs?<\/h2>\n<p>In longstanding PVD (the usual case for patients with intermittent claudication) the tissues have frequently adapted to the shortage of blood and consequently there may be little to see to indicate PVD.\u00a0 On feeling the leg it may be a little cooler and some of the pulses in the leg may be absent. In more severe cases the foot may be quite blue and dusky. The foot may become very pale when lifted up above the heart with the patient lying down and become a bright red when placed dependent (Buerger\u2019s sign, sometimes called sunset foot). The shortage of blood can cause the development of ulcers or gangrene. In the less common situation when patients develop a very sudden (acute) shortage of blood to the leg and foot the limb may turn white (pallor), the pulses will be absent (pulseless), the limb will be cold (poikilothermia), painful, parasthetic (numb or tingling) and may be paralysed.\u00a0 The most important features in a limb with an acute shortage of blood are the numbness and paralysis as these indicate a very severe ischaemia with impending limb loss. Doppler studies may be helpful in both the chronic and acute situations by confirming the diagnosis but are not critical in deciding further management.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Does the blockage in the artery ever re-open?&#8221; tab_id=&#8221;1759014887716-648cb14b-001920d4-347b&#8221;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">Does the blockage in the artery ever re-open?<\/h2>\n<p>The blockages in the arteries never re-open spontaneously.\u00a0 Fortunately, the blockages themselves are not dangerous.\u00a0 It is only the symptoms they cause that are important.\u00a0 Many people live for many years with blockages in the arteries that never cause any serious problems.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Will intermittent claudication get worse?&#8221; tab_id=&#8221;1759352532053-4dfad344-544d&#8221;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">Will intermittent claudication get worse?<\/h2>\n<p>Often when patients develop claudication their symptoms can be worse in the first few months.\u00a0This is because it takes time for the body to adjust to the restricted blood flow.\u00a0 After 2-3 months the situation can improve due to smaller arteries opening up (collateral circulation) and carrying more blood around any blockages. Smaller blood vessels, although not the major blood vessels to the leg, usually carry enough blood to prevent severe disability.\u00a0 Overall about one third of patients with claudication will improve, one third will remain stable and one third will deteriorate.\u00a0 In the majority of patients (&gt;65%) the symptoms will remain stable or improve.\u00a0 The patients whose symptoms deteriorate tend to be those who continue to smoke. Further improvements in walking can be made by taking regular walks.\u00a0 This appears to develop fitness in the affected muscles (much as in an athlete).\u00a0 A formal exercise programme can be a very effective way of improving walking distance. Unless the leg is at risk, it is important not to attempt to improve the blood supply at this early stage in the disease as many patients will develop spontaneous improvement without any help.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;What is the risk of losing my leg?&#8221; tab_id=&#8221;1759352533196-2caf65fb-f167&#8243;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">What is the risk of losing my leg?<\/h2>\n<p>Very few patients with intermittent claudication end up with an amputation and your surgeon will make every effort to avoid amputation, if your leg is at risk.

PVD is an independent risk factor for cardiovascular death and 50% of patients with claudication may die within 10 years from the effects of hardening of the arteries in other parts of the body (Shearman CP, 2002). This is why it is so important to stop smoking and treat other vascular risk factors.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;How can I help my intermittent claudication?&#8221; tab_id=&#8221;1759352780254-0cc96cc3-b7e3&#8243;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">How can I help my intermittent claudication?<\/h2>\n<p>There are several things you can do which may help. The most important are to stop smoking, take regular exercise, lose weight and to have any vascular risk factors treated (<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC1118719\/\" target=\"_blank\" rel=\"noreferrer noopener\">Davies AH 2000<\/a>,\u00a0<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/12637405\" target=\"_blank\" rel=\"noreferrer noopener\">Burns et al 2003<\/a>).\u00a0 This can not only improve your walking and reduce the low risk of limb loss even further, it can also help to reduce problems from generalised atherosclerosis.\u00a0 Vascular risk factors are factors which put a patient at increased risk of hardening of the arteries.<\/p>\n<p><strong>Smoking<\/strong>\u00a0\u2013 If you are a smoker you must make a determined effort to give up completely. Tobacco is harmful on two counts. Firstly, it speeds up the hardening of the arteries, which is the basic cause of the trouble and secondly, cigarette smoke constricts the small collateral vessels and reduces the amount of blood and oxygen to the muscles. The best way to give up is to choose a day when you are going to stop completely rather than trying to cut down gradually. If you do have trouble giving up please ask your doctor who can give you advice on nicotine gum and patches or put you in touch with a support group.\u00a0 If you ever need to have angioplasty or surgery the results are likely to be much poorer if you are still a smoker.<\/p>\n<p><strong>Cholesterol and Diet<\/strong>\u00a0\u2013 It is very important not to put on weight, because the more weight the leg muscles have to carry around the more oxygen and hence blood flow they will need. Your doctor or dietician will give you advice with regard to a weight reducing diet. If your blood cholesterol is high you will need a low fat diet and may also require cholesterol lowering drugs.<\/p>\n<p><strong>Exercise<\/strong>\u00a0\u2013 There is good evidence that patients with intermittent claudication who take regular exercise can increase their walking distance (the distance that they can walk before they have to stop because of pain in the muscles).\u00a0 To develop improvements in walking distance it is important to set aside time to exercise.\u00a0 Walk at an easy pace until the pain comes on and then try to push on a little further.\u00a0 When the pain increases to near maximum, stop and rest until the pain disappears, then return to where you started.\u00a0 Remember the distance that you walked on this first occasion and walk the same distance the next day.\u00a0 Repeat the same exercise distance for one week and on the second week increase the distance slightly.\u00a0 This increased distance is then used for the second week and on the third week the distance is increased slightly further.\u00a0 It is important to only increase the distance walked each week by a small amount otherwise it will become too difficult. It is important to exercise at least 3-4 times each week and very gradually over a period of weeks to increase the walking distance.\u00a0 Initially this can be uncomfortable but you should start to feel real benefit at about 6-8 weeks.\u00a0 It is important not to try and increase your walking distance too rapidly as this can become painful and frustrating.<\/p>\n<p>Supervised exercise programmes are available in some centres.\u00a0 They have shown the most benefits when the exercise session lasted more than 30 minutes, when sessions took place at least 3 times each week, when the patient walked until near maximal pain was reached and when the programme lasted at least 6 months (<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/12477945\" target=\"_blank\" rel=\"noreferrer noopener\">Stewart et al, 2002<\/a>).\u00a0 Exercise can improve walking ability in patients with intermittent claudication by 150 per cent (<a href=\"http:\/\/onlinelibrary.wiley.com\/store\/10.1002\/14651858.CD000990.pub2\/asset\/CD000990.pdf?v=1&amp;t=hdphin7a&amp;s=00c554a3c41184721b7f7f06da3785f033be08cb\" target=\"_blank\" rel=\"noreferrer noopener\">Watson et al, 2008<\/a>). Improvements in walking from an exercise programme appear to be better than any medication including cilostazol (see below) and may be equivalent in the long term to walking improvement from angioplasty.\u00a0 Angioplasty can bring faster improvements to walking ability, but these may not last.\u00a0 Angioplasty also has a number of intrinsic risks. A recent study comparing supervised exercise and angioplasty demonstrated good improvements in up to 50% of patients with exercise alone and at the end of one year there were no major differences between patients undergoing angioplasty and those managing with exercise. Interestingly nearly 70% of patients in the angioplasty groups developed renarrowing of the treated artery by one year (<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/22021102\" target=\"_blank\" rel=\"noreferrer noopener\">Mazari et al, 2012<\/a>).<\/p>\n<p><strong>Flat shoes.\u00a0\u00a0<\/strong>Some patients find that flat shoes can make their symptoms worse.\u00a0 A raised heel to the shoe will raise the heel of the foot and reduces the work that the calf muscles have to perform.\u00a0 This can increase your walking distance.<\/p>\n<p><strong>Blood pressure<\/strong>\u00a0\u2013 It is important that your blood pressure is measured, and if found to be consistently high it should be treated by your doctor.\u00a0 Raised blood pressure can cause further deterioration in hardening of the arteries if left untreated.<\/p>\n<p><strong>Diabetes<\/strong>\u00a0\u2013 If you have diabetes it is important that your sugar levels are tightly controlled as this helps to reduce the risk of future problems.<\/p>\n<p><strong>Thrombophilias.\u00a0\u00a0<\/strong>Sometimes specific treatment for thombophilias can be helpful.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Are there any tablets I can take?&#8221; tab_id=&#8221;1759352850475-ee1412c5-82b4&#8243;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">Are there any tablets I can take?<\/h2>\n<p>There is no medicine that will unblock the arteries.\u00a0 Claims are made for some tablets that dilate the blood vessels but there is little evidence that they make a significant difference, enough to improve the quality of life.\u00a0 Cilostazol is a tablet that is not available in New Zealand, but does appear to improve walking distance.\u00a0 It is best taken at a dose of 100mgs twice daily and produces about 20% improvements in maximal walking distance (<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/11951094\" target=\"_blank\" rel=\"noreferrer noopener\">Strandness DE et al 2002<\/a>).\u00a0 Cilostazol can cause headache, diarrhoea and palpitations.\u00a0<a href=\"http:\/\/www.bmj.com\/content\/338\/bmj.b603.pdf+html\" target=\"_blank\" rel=\"noreferrer noopener\">Naftidrofuryl<\/a>\u00a0is another drug that has shown some small benefits by increasing the maximum walking distance by approximately 50-60 metres, but here also it is doubtful whether this makes a significant difference to quality of life.<\/p>\n<p>A low dose of Aspirin (75milligrammes) is advised\u00a0 for patients with PVD.\u00a0 This is because it makes the blood less sticky and reduces the chances of having further problems in any artery in the body, not only the legs.\u00a0 Aspirin may occasionally cause irritation of the stomach and so if symptoms of indigestion or heartburn develop it should be stopped.\u00a0 Aspirin produces a 20% relative reduction in the risk of heart attack, stroke or death due to vascular disease, in patients with PVD. The absolute benefit is smaller (8.1% reducing to 6.5%, that is 98 out of 100 patients who take aspirin do not have any benefit). Combinations of aspirin-like drugs may also be better than aspirin alone (<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/11412247\" target=\"_blank\" rel=\"noreferrer noopener\">Robless P etal, 2001<\/a>). Clopidogrel is a newer, more expensive, alternative to aspirin which may be used in some patients intolerant of aspirin.\u00a0 It is more expensive than aspirin, but a recent large randomised clinical trial comparing aspirin with clopidogrel did find a very small benefit in favour of clopidogrel in terms of reduction of cardiovascular events (<a href=\"http:\/\/www.columbiamedicine.org\/education\/r\/Cardiology\/ACS\/ASA\/CAPRIE.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">CAPRIE Steering Committee, 1996<\/a>).

Before considering any treatment it is important to obtain more detailed information on the arterial tree by using imaging techniques. This is because the type of interventions possible can only be decided after obtaining a road map of the arteries and then weighing up the risks of intervention against the benefits. An x-ray of the arteries (arteriogram or angiogram) or an ultrasound scan are usually performed first to provide more information about the disease in the arteries. Sometimes short blockages can be stretched open with a balloon (angioplasty) in the x-ray department. This is usually done under local anaesthetic and often involves an overnight stay in hospital.\u00a0 Longer blockages may be bypassed using a plastic tube or vein from the leg (bypass graft). This is a major operation under general anaesthetic and involves being in hospital for about a week to ten days.\u00a0 Very few people with claudication need this operation.\u00a0 In patients who develop critical limb ischaemia (the minority) some form of procedure to restore blood flow to the leg is essential to avoid amputation. The decision about surgery is usually one for you to make in discussion with your vascular specialist after they have explained the likelihood of success, and the risks involved.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Useful links&#8221; tab_id=&#8221;1759014929506-4e94bf49-783d20d4-347b&#8221;][vc_column_text css=&#8221;&#8221;]\n<h2 class=\"wp-block-heading\">Useful links<\/h2>\n<p><a href=\"http:\/\/www.emedicine.com\/emerg\/topic862.htm\">http:\/\/www.emedicine.com\/emerg\/topic862.htm<\/a><\/p>\n<p><a href=\"http:\/\/www.surgical-tutor.org.uk\/default-home.htm?system\/vascular\/peripheral_vascular.htm~right\">http:\/\/www.surgical-tutor.org.uk\/default-home.htm?system\/vascular\/peripheral_vascular.htm~right<\/a><\/p>\n<p><a href=\"http:\/\/www.scotland.gov.uk\/library5\/health\/clpl-00.asp\">http:\/\/www.scotland.gov.uk\/library5\/health\/clpl-00.asp<\/a><\/p>\n<p><a href=\"http:\/\/www.worldwidewounds.com\/2001\/march\/Vowden\/Doppler-assessment-and-ABPI.html\" target=\"_blank\" rel=\"noreferrer noopener\">http:\/\/www.worldwidewounds.com\/2001\/march\/Vowden\/Doppler-assessment-and-ABPI.html<\/a>\u00a0\u2013 Very detailed explanation of Dopplers and ABI measurements<\/p>\n<p><a href=\"http:\/\/www.vascularweb.org\/vascularhealth\/Pages\/peripheral-arterial-disease-(-pad-)-and-claudication.aspx\">http:\/\/www.vascularweb.org\/vascularhealth\/Pages\/peripheral-arterial-disease-(-pad-)-and-claudication.aspx<\/a><\/p>\n<p><a href=\"http:\/\/www.nlm.nih.gov\/medlineplus\/ency\/article\/000170.htm\">http:\/\/www.nlm.nih.gov\/medlineplus\/ency\/article\/000170.htm<\/a><\/p>\n<p><a href=\"http:\/\/en.wikipedia.org\/wiki\/Peripheral_vascular_disease\">http:\/\/en.wikipedia.org\/wiki\/Peripheral_vascular_disease<\/a><\/p>\n<p><strong>Treatment<\/strong><\/p>\n<p><a href=\"http:\/\/archinte.ama-assn.org\/cgi\/content\/abstract\/159\/17\/2041\">http:\/\/archinte.ama-assn.org\/cgi\/content\/abstract\/159\/17\/2041<\/a><\/p>\n<p><a href=\"http:\/\/www.medicine.ox.ac.uk\/bandolier\">http:\/\/www.medicine.ox.ac.uk\/bandolier<\/a><\/p>\n<p><a href=\"http:\/\/www.aafp.org\/afp\/20011215\/1965.html\">http:\/\/www.aafp.org\/afp\/20011215\/1965.html<\/a><\/p>\n[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;References&#8221; tab_id=&#8221;1759015003224-6e58c0d1-e0df20d4-347b&#8221;][vc_column_text css=&#8221;&#8221;]\n<h2>References<\/h2>\n<p><a href=\"http:\/\/ije.oxfordjournals.org\/content\/25\/6\/1172.full.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Leng GC, Lee AJ, Fowkes FG et al.
