This study aimed to determine the prevalence of symptomless internal carotid artery stenosis in consecutive patients presenting with peripheral vascular disease. Duplex ultrasound screening of the carotid arteries was used to determine the degree of stenosis. Co-morbidities were recorded together with age, sex and tobacco use. Internal carotid artery stenosis of > 50% was found in 35% of patients. Among these there was greater than or equal to 70% stenosis in 18% of patients and of this group 5% had an occluded carotid vessel at first presentation. Males presented with peripheral vascular disease and associated carotid stenoses at a younger age than females. Male smokers had a higher prevalence of stenosis (P = 0.036) but all smokers had developed stenoses 3-5 years before non-smokers. Females with abdominal aortic aneurysms had a greater prevalence of carotid stenosis (P = 0.037), and male aneurysmal disease diminished stenosis prevalence (P = 0.023), Men with an elevated serum creatinine were more likely to have a stenosis (P = 0.019), but not women. The other co-morbidities were not specifically associated with carotid artery stenosis. (C) 1998 The Society for Cardiovascular Surgery. Published by Elsevier Science Ltd. All rights reserved.
