The risk of stroke from carotid stenosis is proportionate to the degree of stenosis, but whether this is a direct and linear relationship is unknown. Using the degree of carotid stenosis in 500 patients with asymptomatic carotid bruits as a continuous variable, we plotted the frequency distribution and related this to the risk of ischaemic cerebral events and the progression of the arterial les...

Intravascular lithotripsy (IVL) has emerged as a game-changer for treating complex and severely calcified lesions. There have been increasing cases of IVL usage in different clinical scenarios. Therefore, we reviewed the literature to assess current use non-coronary artery PubMed Embase were accessed case reports series on peripheral disease, excluding conference abstracts. We then calculated m...

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

Background: Carotid ultrasound is useful examination for prevention and management of ischemic stroke and atherosclerosis linked with vascular risk factors. Age and gender are independent factors for stroke. Lacunar stroke is more attributed to chronic hypertension, diabetes mellitus and alcohol abuse, while nonlacunar infarction to carotid artery stenosis and atrial fibrillation. Methods: A re...

BACKGROUND AND PURPOSE Computed tomographic angiography (CTA) is a relatively new and minimally invasive method of imaging intracranial and extracranial blood vessels. The main purpose of this study was to compare CTA to the current gold standard of arterial imaging, digital subtraction angiography (DSA), for the detection and quantification of carotid artery bifurcation stenosis. We also compa...

BACKGROUND AND PURPOSE In the discussion on the cost-effectiveness of screening, precise estimates of severe asymptomatic carotid stenosis are vital. Accordingly, we assessed the prevalence of moderate and severe asymptomatic carotid stenosis by age and sex using pooled cohort data. METHODS We performed an individual participant data meta-analysis (23 706 participants) of 4 population-based s...

OBJECTIVES The purpose of this study was to determine the safety of carotid artery stenting with a unique distal embolic protection system in high-risk patients with severe carotid stenosis. BACKGROUND Previous studies suggest that some patients with carotid stenosis and serious comorbid conditions are at high risk for carotid endarterectomy, and may be safely treated by carotid artery stenti...

We investigated the effects of atherosclerosis in carotid region on cerebral haemodynamics. A total 15 stenosis cases following NASCET criteria were modelled using patient-specific medical i...

The Nurse Practitioner • April 2008 43 cclusive lesions of the internal carotid artery (ICA) caused by atherosclerosis can cause embolic stroke or cerebral ischemia, which may result in significant morbidity, mortality, and long-term disability. Carotid stenosis can be accurately diagnosed by carotid duplex ultrasound imaging. Specific hemispheric symptoms related to potential embolism from a c...

BACKGROUND AND PURPOSE Carotid endarterectomy is one of the main surgical procedures used for carotid stenosis and its recurrence. Besides the setting of a randomized controlled trial for asymptomatic and symptomatic carotid artery stenosis, there is little information about the rate of restenosis after carotid endarterectomy in Hispanics. The purpose of this study is to describe the results of...
