BACKGROUND: Carotid artery near occlusion is a critical degree of stenosis whereby blood flow is decreased and the distal cervical and intracranial internal carotid arteries (ICAs) are prone to collapse. Considering the diminished perfusion and the risk of progression to total occlusion and periocclusive embolism, we performed carotid endarterectomy (CEA) for carotid artery near occlusion. METHODS: Accurate evaluation of tandem stenosis or patency of the post-stenotic ICA in carotid artery near occlusion is often difficult preoperatively...

BACKGROUND: Physical activity reduces the risk of vascular disease. This benefit is not entirely explained through an effect on vascular risk factors. We examined the relationship of physical activity and characteristics of the carotid artery wall in patients with vascular disease or risk factors. METHODS AND RESULTS: Cross-sectional analyses were performed in 9578 patients from the SMART (Second Manifestations of Arterial Disease) study, a prospective cohort study among patients with vascular disease or risk factors...

BACKGROUND: It is currently unclear if carotid artery stenting (CAS) is as safe as carotid endarterectomy (CEA) for patients with significant asymptomatic stenosis. The aim of our study was to perform a systematic review and meta-analysis of trials comparing CAS with CEA. METHODS: On March 17, 2017, a search for randomized controlled trials was performed in MEDLINE and Scopus databases with no time limits. We performed meta-analyses with Peto odds ratios (ORs) and 95% confidence intervals (CIs)...

OBJECTIVES: The purpose was to analyze the agreement and binary accuracy of the degree of internal carotid artery stenosis (ICAS) as determined by 4-dimensionally (4D) real-time gray-scale guided 3-dimensional (3D) color-Doppler ultrasonography (3DC-US) (4D/3DC-US) compared with catheter angiography (CA) and duplex ultrasonography (DUS). This study hypothesized that 4D/3DC-US is noninferior to CA and DUS in grading ICAS in selected patients. BACKGROUND: Clinical stratification in patients with ICAS largely depends on a patient's symptomatic status and the degree of stenosis...

The RING finger protein 213 (RNF213) is an important susceptibility gene for moyamoya disease (MMD) and is also implicated in other types of intracranial major artery stenosis/occlusion (ICAS); however, the role of RNF213 in the development of ICAS including MMD is unclear. The constitutive expression of the RNF213 gene is relatively weak in brain tissue, while information regarding the expression patterns of the RNF213 gene under cerebral ischemia, which is one of characteristic pathologies associated with ICAS, is currently limited...

Background: Previously, we reported on vascular cognitive impairment (VCI) templates, consisting of patients with VCI associated with carotid stenosis (>60%) using a quantitative electroencephalographic (EEG) technique called neuronal activity topography (NAT). Here using the VCI templates, we investigated the hypothesis that internal carotid artery-intima-media thickness (ICA-IMT) is associated with EEG spectrum intensity (sNAT) and spectrum steepness (vNAT). Methods: A total of 221 community-dwelling elderly subjects were recruited...

BACKGROUND AND PURPOSE: Calcification of the intracranial vasculature is an independent risk factor for stroke. The relationship between luminal stenosis and calcium burden in the intracranial circulation is incompletely understood. We evaluated the relationship between atherosclerotic calcification and luminal stenosis in the intracranial ICAs. MATERIALS AND METHODS: Using a prospective stroke registry, we identified patients who had both NCCT and CTA or MRA examinations as part of a diagnostic evaluation for ischemic stroke...

Carotid artery atherosclerosis remains one of the major causes of stroke. The efficacy of carotid artery recanalization has already been established and is considered significant for symptomatic stenosis >70% and moderate for stenosis between 50-69 %. Regarding asymptomatic stenosis, carotid artery recanalization should be reserved for carefully selected patients with a stenosis between 70-90 % and an estimated procedural risk at less than 3 %. Two therapeutic options are currently available : angioplasty with stent placement and endarterectomy...

Platelet degranulation at the site of vascular injury prevents bleeding and may affect the chronic vascular wound healing response. Transforming Growth Factor (TGF)-β1 is a major component of platelet α-granules known to accumulating in thrombi. It was our aim to determine the role of TGFβ1 released from activated platelets for neointima formation following arterial injury and thrombosis. Mice with platelet-specific deletion of TGFβ1 (Plt.TGFβ-KO) underwent carotid artery injury. Immunoassays confirmed the absence of active TGFβ1 in platelet releasates and plasma of Plt...

INTRODUCTION    The corrective effect of carotid endarterectomy (CEA) on disturbed ophthalmic artery flow in patients with a significant internal carotid artery stenosis (ICAS) presenting with ocular ischemic syndrome (i.e., symptomatic patients) is well established. However, no clear evidence exists regarding the efficacy of CEA for improvement of neuro-retinal function in patients without symptoms of ocular ischemic syndrome. OBJECTIVES    We determined the effects of CEA on retinal function in asymptomatic patients with hemodynamically significant internal carotid artery stenosis...

INTRODUCTION: In ST-elevation myocardial infarction (STEMI) patients, multisite artery disease represents a serious issue influencing evolution, outcomes and prognosis. We evaluated for the first time the power of the Myocardial Infarction SYNTAX Score (MI SS) and Clinical SYNTAX Score (MI CSS) as predictors for renal artery stenosis (RAS) in STEMI. We also stratified the study population according to the two scores, and identified the variables correlated with the higher score. MATERIAL AND METHODS: We used data from the REN-ACS study, which included 181 consecutive patients prospectively investigated for presence of RAS (through renal angiography), arterial stiffness (carotid-femoral pulse wave velocity, cf-PWV) and hydration status (bioimpedance)...

INTRODUCTION: It is hypothesized that cerebral hypoperfusion promotes the development of Alzheimer pathology. We therefore studied whether longstanding cerebral hypoperfusion is associated with Alzheimer pathology in nondemented humans. METHODS: Cerebral blood flow and β-amyloid ((18)F-Flutemetamol) positron emission tomography retention were assessed in eleven patients with unilateral occlusion of precerebral arteries resulting in chronic and uneven hypoperfusion...
