| description | <ul><li><strong>BACKGROUND</strong>: The prevalence of carotid artery stenosis (CAS) in the&nbsp; eneral population is not high enough to justify screening programs. This study was done to determine the prevalence of asymptomatic carotid artery stenosis (ACAS) among patients with severe peripheral vascular disease (PVD).</li><li><strong>METHODS</strong>: Between March 2005 and February 2006, 54 consecutive&nbsp; atients with severe PVD admitted at a vascular surgery unit and underwent carotid duplex scanning in a prospective study. A&nbsp; uestionnaire was used to collect data concerning known risk factors. Significant CAS was defined as a stenosis of 70% or greater.</li><li><strong>RESULTS</strong>: The mean age was 62.5 years (51-72). Out of 54 patients, 2 (3.7%) had an occluded internal carotid artery. Significant CAS was found in 9 (16.7%) and its presence was correlated with diabetes, hypertension, hypercholesterolemia, hypertriglyceridemia, coronary artery disease, severity of symptoms, ankle-brachial index, and carotid bruit. On multivariate analysis, only hypercholesterolemia and carotid bruit seemed to have independent influence.</li><li><strong>CONCLUSION</strong>: The prevalence of significant ACAS is higher among&nbsp; atients with severe PVD. This patient population may indicate a&nbsp; uitable subgroup for screening of ACAS, especially when hypercholesterolemia and carotid bruit are present.</li><li><strong>KEYWORDS</strong>: Carotid artery stenosis, duplex ultrasound scanning, peripheral vascular disease, carotid endarterectomy,</li><li>cerebrovascular accident.</li></ul> |
