For most of the large arterial vessels, surgeons can rely on a constant anatomy. In head and neck surgery, the common carotid arteries are important landmarks, defining the plane of the dissection during radical neck surgery (Ord & Ward-Booth, 1986). Conventional angiography is considered the most accurate technique for diagnosis of carotid bifurcation diseases, such as stenosis (Schwartz et al...

Numerous CFD studies have been performed on the motivation to elucidate the role of hemodynamic forces in the development of atherosclerosis in the coronary arteries and the carotid bifurcation artery. In order to improve CFD predictions, and to consider CFD as a clinical diagnostic or treatment planning tool, there is a need to ensure its accuracy and reliability through a systematic approach ...

Background and Purpose—Why is carotid plaque often so strikingly asymmetrical within individuals, and why does the extent of disease vary so considerably between individuals with similar systemic risk factors? Variability of carotid bifurcation anatomy is a possible explanation. Flow models suggest that vessel anatomy, in particular vessel diameter and area ratios, affects plaque formation at a...

STROKE DUE TO ATHEROMATOUS DISEASE of the carotid artery is preventable by endarterectomy if a causative lesion is identified early enough. Despite its limitations arteriography remains the definitive test for carotid disease. Ideally, arteriography should be done when the risk of stroke is considerably greater than the risk of a complication from the diagnostic procedure. The warning signs of ...

A new algorithm is proposed for the correct identification of the lumen and bifurcation contours of the carotid artery in ultrasound B-mode images. The algorithm uses hipoechogenic characteristics to guide the lumen identification and echogenic characteristics to detect the artery bifurcation. The input image is preprocessed for speckle removal by an anisotropic diffusion filter and morphologic...

The purpose of this study was to propose an innovative approach of setting outlet boundary conditions for the computational fluid dynamics (CFD) simulation of human common carotid arteries (CCAs) bifurcation based on the concept of energy loss minimisation at flow bifurcation. Comparisons between this new approach and previously reported boundary conditions were also made. The results showed th...

Management of the symptomatic multiple stenosis of supra-aortic vessels (MSSVs) in a "bovine" aortic arch (BAA) configuration is infrequently reported. The optimal treatment choice remains debatable. A successful hybrid treatment for a proximal critical stenosis of the innominate and left common carotid artery was performed in a high-risk patient with a tandem symptomatic lesion in the right ca...
