background: the incidence of stroke is 2.1-5.2% in bypass surgery patients with a mortality of 0-38%. this study was designed to evaluate the incidence of significant carotid artery stenosis and its related risk factors in candidates for coronary artery bypass graft (cabg) surgery. methods: 1045 consecutive candidates for cabg underwent carotid artery doppler examination in a prospective study....

vertebrobasilar insufficiency is the cause of cerebrovascular accidents in 20% of cases. there are few reports regarding spectral doppler indices (sdis) of vertebral arteries (vas) normal blood flow. the objective of this study was to provide basic reference data about sdis of vas normal blood flow separately and in comparison with internal carotid arteries (icas) and common carotid arteries (c...

background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...

background the behcet disease is a multisystemic disease with involvement of vessels. objectives our aim is to evaluate the frequency of carotid artery disease in asymptomatic carotid artery involvement in patients with behcet disease and compare the results with a control group. patients and methods fifty patients with behcet disease who were asymptomatic for any vascular involvement and 50 he...

this is retrospective double-blind research, which was carried out in imam khomeini hospital in order to study the accuracy of color doppler ultrasonography for detecting the site and grade of stenosis in cervical carotid artery. 40 patients with mean age of 62 years studied with color doppler before dsa angiography. the most common sites of stenosis were left internal carotid (39.5%) and right...

introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...
