BACKGROUND Vascular disease resulting from arteriosclerosis is a severe worldwide health risk. Early diagnosis and intervention is important to control adverse cerebral and cardiovascular events. The aim of this study was to assess the potential predictors of mortality in patients submitted to coronary bypass surgery. METHODS Cohort study included asymptomatic cerebrovascular disease patients...

Abstract We report a case of 4-year-old boy who presented with moyamoya disease associated midaortic syndrome. He had been treated for severe persistent hypertension until he suffered multiple episodes seizure and cerebral ischemic attack. Cerebral angiography showed bilateral terminal internal carotid artery stenosis. Angiographic survey stenosis abdominal aorta proximal renal arteries. This i...

conclusions according to the results, there were no significant and meaningful differences comparing acs and csa groups of patients by ecds using three indicators of stenosis, plaque morphology and imt as indicators of atherosclerosis. results also display that patients with acs had more stenosis, more plaque and thicker intima–media, but these differences were not statistically significant (p ...

BACKGROUND AND PURPOSE Carotid artery stenosis is an important etiologic factor of stroke related to coronary artery bypass surgery. We evaluated clinical and laboratory factors to identify biomarkers for pre-existing carotid artery stenosis in patients undergoing coronary artery bypass surgery. METHODS Between June 2006 and September 2008, 811 patients aged ≥50 years underwent preoperative c...

BACKGROUND The Carotid Artery Insufficiency Retinopathy (CAIR) is an uncommon sign of carotid artery obstruction. It is mainly found in patients with complete occlusion or severe obstruction of internal Carotid Artery (ICA). Retinopathy is caused by progressive and chronic hypoxia to ocular tissues. The purpose of the study is to describe the variable presentation of CAIR in patients with inter...

OBJECTIVE To determine frequency of carotid artery disease in patients undergoing elective coronary artery bypass grafting (CABG) using Doppler sonography. STUDY DESIGN Observational study. PLACE AND DURATION OF STUDY Radiology Department, The Aga Khan University Hospital, Karachi, from January 2005 to September 2008. METHODOLOGY Patients with known cardiovascular disease waiting for CABG...

Introduction Approximately one-quarter of ischaemic strokes involve the posterior or vertebrobasilar circulation. 1,2 Stenosis of the vertebral artery can occur in either its extra-or intracranial portions, and may account for up to 20% of posterior circulation ischaemic strokes. 3–6 Stenotic lesions, particularly at the origin of the vertebral artery, are not uncommon. In an angiographic study...

OBJECTIVE To determine the prevalence and risk factors for radiation-induced carotid stenosis in patients with malignant neoplasms of the head and neck. DESIGN Prospective cross-sectional screening of extracranial carotid stenosis by color-flow duplex ultrasonography with an analysis of demographic and comorbid risk factors. SETTING Tertiary oncology and vascular referral center. PATIENTS...

Evaluation of elastic properties of major arteries is subject of great interest with respect to the development of vascular diseases. In this study changes in diameter and cross-sectional area, stress-strain elastic modulus and stiffness of the common carotid arteries in healthy and atherosclerotic women and men were evaluated by using indirect end pressure changes. Variations in diameter and c...
