Bifurcation aneurysms (carotid bifurcation aneurysms, top of basilar artery aneurysms and middle cerebral artery aneurysms) are frequently treated by endovascular treatment (EVT) but their treatment is sometimes difficult singularly when the neck is wide. The "remodelling technique" is used for the treatment of these difficult aneurysms. However, the use of this technique is more complicated in...

Management of carotid bifurcation stenosis is a cornerstone of stroke prevention and has been the subject of extensive clinical investigation, including multiple controlled randomized trials. The appropriate treatment of patients with carotid bifurcation disease is of major interest to the community of vascular surgeons. In 2008, the Society for Vascular Surgery published guidelines for treatme...

BACKGROUND AND PURPOSE The likelihood that carotid plaque will give rise to cerebral ischemia probably relates to the degree of arterial stenosis and to plaque morphology. The aim of this study was to assess whether features seen at CT angiography might be used to predict carotid plaque stability by comparing CT angiograms with histopathologic examinations of the carotid artery bifurcation. M...

A mathematical model for the flow of human blood through an artery bifurcation is studied using finite element analysis (FEA). The FEA has been applied for a two-dimensional steady flow of an in-viscous fluid through different geometries. The flow through a two-dimensional model of a carotid artery bifurcation has been simulated. The velocity profiles through the bifurcation branches were compu...

INTRODUCTION We aimed to show the spread of local anesthetic following an ultrasound-guided, double-injection technique of a carotid sheath block before carotid endarterectomy. METHODS The study included 15 patients scheduled for elective carotid endarterectomy. The carotid sheath block was performed after ultrasound-guided localization of the carotid bifurcation (level C4-C6) at the posterio...

Introduction: Nitroglycerin is a fast-acting drug that rapidly dilates coronary arteries and thus increases blood flow to these vessels, and increases the blood flow through the lateral vessels to low blood areas. It also reduces both end diastolic pressure and volume of the left ventricular. However, the effect of nitroglycerin on the circulation hemodynamic is not known. Caro...

The external carotid artery originates branches to face structures. The superior thyroid, lingual and facial arteries are originated from this vessel as artery trunks or separately. The aim of this study was to determinate the arrangement frequency of these artery branches. For this, thirty six (36) hemi-heads of adult cadavers from both genders were studied. The anatomic parts were fixed in 10...

The alterations in cerebral perfusion with graded hypercapnia were measured in the baboon using the intra-carotid xenon clearance technique. In addition, the tidal percent of COj and the blood flow in the common carotid artery were measured using a capnograph and an electromagnetic flowmeter respectively. The delay times between the induced increments in tidal respiratory percent of CO] and the...

Although atherosclerosis has been widely investigated at carotid artery bifurcation, there is a lack of morphometric and hemodynamic data at different stages of the disease. The purpose of this study was to determine the lesion difference in patients with carotid artery disease compared with healthy control subjects. The three-dimensional (3D) geometry of carotid artery bifurcation was reconstr...
