To our knowledge, the utility of coronary covered stents in the treatment of atherosclerotic carotid artery stenosis has not been defined in the English-language literature. Covered stents may prevent microembolic complications in select atherosclerotic carotid lesions, as they exclude the atherosclerotic lesion from the circulation by pressing the plaque against the vessel wall. Our early clin...

BACKGROUND AND PURPOSE Various Doppler criteria have been used to predict hemodynamically significant carotid stenosis. This study was performed to elucidate whether hemodynamically significant stenosis can be predicted indirectly by the blood flow velocity in the common carotid artery (CCA) measured with duplex ultrasonography in patients with unilateral stenosis of internal carotid artery (IC...

PURPOSE Accurate calculation of the percentage of stenosis is crucial for identifying candidates for endarterectomy. Our goal was to quantify the reduction in diameter of the distal internal carotid artery (ICA) as a function of proximal ICA stenosis and to discuss the implications of distal ICA narrowing on the calculation of percentage of stenosis using the criteria of the North American Symp...

OBJECTIVE To assess the early results of combined coronary artery bypass graft surgery and carotid endarterectomy. DESIGN Retrospective and ongoing analysis of patients who underwent combined coronary artery bypass graft surgery and carotid endarterectomy. SETTING Cardiothoracic unit in a London teaching hospital. PATIENTS From June 1987 to March 1995, 64 patients were identified. They we...

BACKGROUND Restoration of carotid artery patency is one of the most frequently performed operations in vascular surgery. One of the most important problems that occur both short- and long-term after carotid endarterectomy is recurrent stenosis. Despite advances in imaging studies and better knowledge of the mechanisms of atherogenesis, the mechanism of restenosis remains unclear. Patients with ...

In severe valvular aortic stenosis, obstruction to ventricular contraction results in prolonged ventricular systole and diminished peak flow velocity. This may translate into weak or impalpable peripheral arterial pulses. We report a case of severe aortic stenosis associated with an impalpable carotid pulse (in the absence of local carotid artery disease) that became easily detectable following...

Objective: CASPER Rx stent (Terumo, Tokyo, Japan) is one of the dual-layer micromesh stents for carotid artery stenosis. Although it expected to be safe and efficacious even vulnerable plaque, we report a case in-stent occlusion 2 weeks after stenting with stent.

BACKGROUND It is recognized that complicated plaque largely accounts for the morbidity and mortality from atherosclerosis. Ideally, investigation of symptomatic and asymptomatic patients would identify atheromatous plaques independently of stenosis. We have previously shown that a magnetic resonance direct thrombus imaging (MRDTI) technique demonstrates complicated atheroma as high signal withi...

Purpose. To correlate ultrasonographic peak systolic velocity (US-PSV) and 64-row multidetector computed tomography angiography (MDCTA) with advanced vessel analysis (AVA) software in the quantification of 50-70% carotid artery stenosis. Materials and methods. 199 consecutive patients (247 arteries) with internal carotid artery (ICA) or third proximal bifurcation stenosis. Each patient was stud...

BACKGROUND Ischemic stroke and glioblastoma multiforme have similar features on anatomic magnetic resonance imaging (MRI) and thus may require a surgical biopsy for a definitive diagnosis. CASE PRESENTATION A 55-year-old male complained of dysphasia for 4 weeks and continuous deterioration for 5 days. Cerebral infarction was considered based on MRI, which showed hyperintensity at the border z...
