Introduction: Prevalence of stroke following coronary artery bypass graft surgery (CABG) is % 2.1-5.2 and associated with high mortality. The purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing CABG surgery. Methods: This cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (CABG) in...
Sixty carotid bifurcations in 34 symptomatic patients were examined prospectively with ultrasound (continuous wave Doppler and high resolution, B-mode imaging) and intravenous digital subtraction angiography (IV-DSA). The overall quality of examination was better with DSA than with ultrasound. Imaging of the external carotid artery was particularly difficult with sonography. For evaluation of t...
Usefulness of Doppler Sonography of Ophthalmic Artery for Occlusive Internal Carotid Artery Diseases
Background & Aims: Due to the high incidence of breast cancer, the use of easy, safe, noninvasive and readily available diagnostic procedures that can accurately determine the initial stages of the disease and its spread is very important. Ultrasonography as a method may be able to realize these goals and to help patients and physicians. The aim of this study was to evaluate diagnostic val...
Background & Objective : Several indices have been introduced to estimate arterial stiffness that based on changes in brachial blood pressure. But because of the error resulted by the substitution of brachial blood pressure instead of the other central arteries, such as carotid, it will be very important to present elastic parameter based on the mechanical models without any emphasis on brach...
background: the presence of significant carotid stenosis in coronary artery bypass grafting (cabg) patients increases the risk of either transient ischemic attack or stroke. however, there is a dearth of data on the risk for patients with unilateral total occlusion of the carotid artery. we herein report our results of cardiac surgery in patients with unilateral total occlusion of the carotid a...
Doppler sonographic criteria for assessing peripheral lymph nodes ! Introduction B-mode criteria provide the foundation for the sonographic identification of peripheral lymph nodes as normal or pathological and for differential diagnosis. “Sonography of Peripheral Lymph Nodes Part 1: Normal Findings and B-Image Criteria” therefore provides a comprehensive description of the sonographic appearan...
Abstract Background: Epidemiologic studies have shown the relationship of maternal hemoglobin level and abnormal findings in uterine Doppler sonography with pregnancy- related complications. In this study, we evaluated the relationship of uterine artery Doppler velocimetry findings and hemoglobin level with the outcomes of pregnancy in women with preeclampsi...
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....
AIM Population studies have shown obesity and diabetes to be risk factors for atherosclerosis. We assessed changes in the common carotid arteries in rat models of obesity and diabetes without hypertension. METHODS Twenty 30-week-old male spontaneously diabetic and obese model Otsuka Long-Evans Tokushima Fatty (OLETF) and 20 control Long-Evans Tokushima Otsuka (LETO) rats were used in the expe...
