| pubmed-article:485960 | pubmed:abstractText | Many patients with intermittent claudication improve due to development of collateral vessels. Only a small proportion worsen, and few progress to severe ischaemia with the risk of amputation. Accordingly, most patients can be reassured and treated expectantly. Those patients have a reduced life expectancy compared with the population at large. Thus, surgical treatment should be reserved for patients who are severely restricted by claudication. The early technical results of arterial reconstruction for claudication are excellent. However, the late results are much worse in patients who continue to smoke. Nowadays, the complication rate from surgery is low. | lld:pubmed |
