screening programs. This study was done to determine the prevalence of asymptomatic carotid artery stenosis (ACAS) among patients with severe peripheral vascular disease (PVD). METHODS: Between March 2005 and February 2006, 54 consecutive patients with severe PVD admitted at a vascular surgery unit and underwent carotid duplex scanning in a prospective study. A questionnaire was used to collect data concerning known risk factors. Significant CAS was defined as a stenosis of 70% or greater. RESULTS: 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. CONCLUSION: The prevalence of significant ACAS is higher among patients with severe PVD. This patient population may indicate a suitable subgroup for screening of ACAS, especially when hypercholesterolemia and carotid bruit are present.
