Ultrasound of the carotid and vertebral arteries.
نویسنده
چکیده
Ultrasound plays an important role in the assessment of carotid arterial disease, complimentary to other imaging modalities. However, ultrasound does have limitations, not least the requirement of a high degree of operator skill. Recent advances in ultrasound technology will strengthen its role by improving accuracy. This review discusses the role of ultrasound in assessing the carotid arterial system with emphasis on evaluating stenosis.

Carotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion
Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
متن کاملAnatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
متن کاملA case of aberrant bilateral vertebral arteries orgin presenting with right VA dissection
Background: Knowledge of variations in the origin of vertebral artery (VA) is indispensable to vascular surgeons. Aberrant origin of vertebral artery on either side is an uncommon finding. There are unilateral and bilateral variability in VA origin. Case presentation: We present a case of vertebral artery dissection who was found to have bilateral VAs aberrant origin. The right VA took origin ...
متن کاملSpontaneous dissection of the carotid and vertebral arteries.
The carotid color Doppler ultrasound is usually the first imaging modality employed for the assessment of patients with cerebrovascular symptoms. The recognition of the distal stenoocclusive flow pattern is key for the detection of spontaneous dissection of the internal carotid and vertebral arteries in young patients who present cerebral ischaemic signs. We present six cases of patients whose ...
متن کاملEvaluation of Diameter Changes, Stress-strain Elastic Modulus and Stiffness in Normal and Atherosclerotic Common Carotid Arteries in Both Sex Based on End Pressure Variation
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...
متن کاملEvaluating the effect of stenosis increase and pulsatile blood pressure on effective stress distribution in viscoelastic finite element model based on carotid artery ultrasound images
The aim of this study is to evaluate the changes of effective stress distribution in plaque by progressing to the stenosis throat and to assess the pulsatile pulse pressure effect on effective stress of a viscoelastic finite-element model of carotid arteries having less and more than 50% stenosis. In-vivo geometries of the arteries were reconstructed using consecutive transverse ultrasound imag...
