The complete segmentation of the common carotid artery (CCA) bifurcation in ultrasound images is important for the evaluation of atherosclerosis disease and the quantification of the risk of stroke. This requires the extraction of the intima-media complex (IMC), the delineation of the lumen the atherosclerotic carotid plaque and measurement of the artery stenosis. The current research proposes ...

The common carotid artery (CCA) usually bifurcates at the level of the upper border of the thyroid cartilage (C3 –4 cervical vertebrae) or the body of the hyoid bone (C3) [1]. Despite the fact that bifurcation can occur at any level in the neck, low level bifurcation occurs far less frequently than at higher levels [2,3]. The CCA is close to many vital structures in the neck, including the trac...

The precise sequence of events leading to carotid plaque vulnerability is as yet unknown, and the majority of ischemic strokes seem to result from atherosclerotic plaque rupture or thrombus propagation at the carotid bifurcation.1 Traditionally, the surgical approach of carotid endarterectomy is well accepted for the treatment of symptomatic and severe asymptomatic carotid stenosis.2,3 More rec...

PURPOSE Hemodynamics has a key role in atheropathogenesis. Indeed, atherosclerotic phenomena occur in vessels characterized by complex geometry and flow pattern, like the carotid bifurcation. Moreover, lifestyle is a significant risk factor. The aim of this study is to evaluate the hemodynamic effects due to two sedentary lifestyles - sitting and standing positions - in the carotid bifurcation ...

A novel algorithm is proposed for the segmentation of the lumen and bifurcation boundaries of the carotid artery in B-mode ultrasound images. It uses the image contrast characteristics of the lumen and bifurcation of the carotid artery in relation to other tissues and structures for their identification. The relevant ultrasound data regarding the artery presented in the input image is identifie...

Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...

Acute embolic occlusion of the intracranial internal carotid bifurcation is associated with a poor prognosis. Recanalization rates of this lesion with intravenous or intraarterial thrombolysis are exceedingly low. We describe the use of balloon angioplasty after failed thrombolysis to achieve immediate recanalization of acute carotid T occlusions in two patients. At 1-month follow-up, both pati...

Fig. 3: Segmental distribution of the individual upper 15% of OSI and lower 15% of WSSmag in all analyzed 64 carotid arteries and 6 analysis planes in the CCA and ICA. The segmental distribution in the central graphs represents the number of volunteers who had potentially atherogenic low WSSmag or high OSI in the respective carotid region. Three-dimensional Assessment of Wall Shear Stress Distr...

Large pseudoaneurysms which compress the parent vessel are challenging lesions to successfully treat with endovascular therapy. We describe the endovascular treatment of a giant extracranial carotid artery (ECCA) pseudoaneurysm resulting in substantial mass effect on the common carotid artery (CCA) bifurcation using a telescoping dual covered stent graft construct. A 56-year-old male was diagno...

We determined the angiographic presence of extracerebral and intracerebral arterial disease in 122 patients with minor stroke within the carotid territory; we excluded patients with a recognized cardiac source of emboli. Based on clinical features and computed tomographic findings, patients were classified as having lacunar infarcts (n = 61), nonlacunar infarcts (n = 53), and infarcts of indete...
