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...

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...

Background and purpose : Ârterial embolism is one of the most prevalent cause of transient ischemic attack (TÏÂ) and other types of brain ischemias and about 5o% of TÏÂ patiens have vascular stenosis. Therefore the presence of mild atherosclerotic plaques in carotid arteries, as a source of embdlism in causing TÏÂ and other brain strokes are of a great importance. Ïn present study the ...

Background and purpose: Recommended treatment for patients with carotid stenosis, is Carotid Endarterectomy (CEA) that is more effective in preventing stroke compared to other therapies. The purpose of this study was to evaluate morbidity and mortality rate in patients with carotid stenosis after CEA. Material and Methods: In this descriptive study, 138 patients undergoing CEA admitted in the ...

Background: In many studies, Serum lipoprotein(a) [Lp(a)] levels considered as an independent risk factor for atherosclerosis. The aim of this study was to assess the association between Lp(a) and cervical carotid artery stenosis in one sample the Iranian population. Methods: As a cross sectional study, between June 2004 and January 2005, at Tehran Heart Center, 1189 candidates for any kind of...

Introduction: Digital Subtraction Angiography (DSA) is the standard method for detection of carotid artery stenosis. This technique has high radiation dose. With the progress of imaging techniques, noninvasive or minimally invasive methods like the CT angiography, MR angiography and ultrasonography with Doppler or Duplex mode were applicable. This study aimed to evaluate and assesse the results...

Background: Carotid endarterectomy (CEA) is a standard method for patient with significant carotid stenosis but direct surgical repair via carotid endarterectomy may not be a good option in some patients because of the overall health status that may make the surgery too risky. Carotid angioplasty and stenting (CAS), is a relatively new procedure for the treatment of carotid artery disease in pa...
