BACKGROUND AND PURPOSE All carotid stenosis ratio methods are based on the inability of digital subtraction angiography to measure in millimeters. Each method has potential flaws. The Carotid Stenosis Index (CSI) was designed to reduce ambiguities of NASCET and ECST ratios. We test this method's ability to correctly estimate carotid stenosis using direct computed tomography angiography millimet...

BACKGROUND A major debate in cerebrovascular medicine today is over the choice of the best treatment to implement for stenosis of the carotid artery. Carotid artery stenting is a less invasive technique than endarterectomy for the treatment of carotid stenosis, and is becoming more widely performed, particularly on patients with carotid artery stenosis who present also with comorbidities. To ad...

In vitro studies have demonstrated that geometry of the carotid bifurcation predicts blood flow alterations associated with atherosclerotic plaque formation. We investigated intraindividual asymmetry of carotid atherosclerosis by measuring geometric aspects of the carotid bifurcation. We measured diameter stenosis, the internal carotid artery/common carotid artery area ratio, and the angle of t...

BACKGROUND Previous studies demonstrated a modest association between C-Reactive Protein (CRP), stenosis of carotid artery, and carotid Intima-Media Thickness (IMT) in general population. During present study, we aimed to evaluate the relationship between High Sensitivity C-Reactive Protein (hsCRP) and Common Carotid Intima-Media Thickness (CCIMT) in patients who candidate for Coronary Artery B...

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 ...

Carotid endarterectomy (CEA) is a beneficial procedure for patients with high-grade carotid stenosis. However, patients with bilateral carotid stenosis have a higher surgical risk during CEA. Since the introduction of carotid stenting (CAS) may decrease some of the surgical complications of CEA, a combined treatment using CEA and CAS may be favorable for patients with bilateral carotid stenosis...

A 58-year-old man presented for re-evaluation of an asymptomatic right-sided carotid stenosis. Besides conventional ultrasound techniques, we could confirm a moderate right internal carotid artery stenosis by the innovative inverse fly-through technique (figure). Regular checkups were initiated. There is growing evidence that 3D ultrasound may provide new possibilities for evaluating carotid di...

INTRODUCTION Duplex ultrasonography is an excellent non-invasive screening tool for carotid artery stenosis. The aim of this study was to evaluate optimal ultrasonographic criteria for determination of internal carotid artery stenosis with reference to digital subtraction angiography. MATERIALS AND METHODS From January 1995 to December 2003, 114 symptomatic patients underwent both duplex ultr...

BACKGROUND AND PURPOSE Traditional vascular risk factors do not completely explain the asymmetry, racial, and sex differences in carotid artery disease. Carotid anatomy and geometry may play a role in the pathogenesis of internal carotid artery (ICA) stenosis, but their effects are unknown. We hypothesized that carotid artery anatomy and geometry would be independently associated with ICA steno...

Atherosclerosis is the most frequent cause of extracranial cerebrovascular disease, and represents an important cause of stroke and transient ischemic attack, being responsible for up to 15% to 20% of all ischemic strokes (1). Carotid artery stenosis has long been recognized as an important risk factor. In most studies of carotid artery stenosis intervention, clinically important stenosis, beyo...
