Carotid stenosis is a major cause of stroke and timely intervention with stenting manipulation can significantly reduce the risk of secondary stroke. The impact of stenting procedures on patient functional capabilities has not yet been explored. The primary aim of this study was to examine associations between periprocedural carotid sonography parameters and post-treatment functional capabilities in stroke patients.Sixty-seven patients who received carotid stenting at 1 angiography laboratory were included...

BACKGROUND: and Purpose: The treatment strategy for bilateral carotid stenosis (BCS) is not clear. We report our experience of treating 12 patients with BCS using separate carotid artery stenting (CAS) using the restrict protective method. The order of treatment site and the protective method are also discussed. MATERIALS AND METHODS: Between April 2012 and November 2016, 24 lesions in 12 patients (range, 44-83 years; mean, 71 years; 1 woman) underwent CAS at Kariya Toyota General Hospital...

OBJECTIVE: MRI technique known as Territorial ASL (TASL) allows for noninvasive visualization of their perfusion territories. The objective of this study was to use TASL to assess the relationship between perioperative changes in the perfusion territories of ICA and CBF after carotid revascularization. METHODS: In 32 patients, ICA perfusion volume (PV) and CBF were measured before and after CEA/CAS using TASL and SPECT, respectively. ICA flow was measured during CEA before and after reconstruction, using an electromagnetic flowmeter...

INTRODUCTION: Von Willebrand factor propeptide (VWF:Ag II) is proposed to be a more sensitive marker of acute endothelial activation than von Willebrand factor antigen (VWF:Ag). Simultaneous data on VWF:Ag and VWF:Ag II profiles are very limited following TIA and ischaemic stroke. METHODS: In this prospective, observational, case-control study, plasma VWF:Ag and VWF:Ag II levels were quantified in 164 patients≤4weeks of TIA or ischaemic stroke (baseline), and then ≥14days (14d) and ≥90days (90d) later, and compared with those from 27 healthy controls...

OBJECTIVE/BACKGROUND: Carotid endarterectomy (CEA) prevents future stroke, but this benefit depends on detection and control of high peri-operative risk factors. In symptomatic patients, diastolic hypertension has been causally related to procedural stroke following CEA. The aim was to identify risk factors causing peri-procedural stroke in asymptomatic patients and to relate these to timing of surgery and mechanism of stroke. METHODS: In the first Asymptomatic Carotid Surgery Trial (ACST-1), 3,120 patients with severe asymptomatic carotid stenosis were randomly assigned to CEA plus medical therapy or to medical therapy alone...

BACKGROUND: Carotid atherosclerosis is responsible for ~20% of ischemic strokes, but it is unclear whether carotid disease is associated with the presence of downstream silent brain infarction (SBI). We performed a systematic review and meta-analysis to study the relationship between SBI and 2 separate manifestations of carotid atherosclerosis, carotid intima-media thickening (IMT) and luminal stenosis. METHODS: Ovid MEDLINE, Ovid Embase, and the Cochrane Library Database were searched with an additional search of references and citing articles of target studies...

Elevated homocysteine (Hcy) levels are predictors of cardiovascular disease (CVD). Hyperhomocysteinemia has also been associated with total and CVD mortality. However, whether Hcy is just a marker or plays a causal role in CVD remains to be elucidated. In this narrative review, we discuss the associations between Hcy and non-cardiac vascular diseases, namely stroke, peripheral artery disease (PAD), carotid artery disease, chronic kidney disease (CKD), atherosclerotic renal artery stenosis (ARAS), abdominal aortic aneurysm (AAA) and erectile dysfunction (ED)...

BACKGROUND AND PURPOSE: Atrial fibrillation (AF) and significant carotid artery stenosis (CAS) often coexist in patients with acute stroke but whether CAS affects the stroke recurrence rate in anticoagulated AF patients is largely unknown. The effect of concomitant CAS on both short- and long-term prognosis after stroke in patients with AF was evaluated. METHODS: The multicentre, retrospective FibStroke registry included AF patients with an ischaemic stroke or transient ischaemic attack (TIA) during 2003-2012...

BACKGROUND AND PURPOSE: Because magnetic resonance imaging (MRI) focuses on the morphological characteristics of carotid artery plaques, its diagnostic value with respect to plaque vulnerability is limited. We examined the correlation between N(ε)-(carboxymethyl)lysine (CML), a main chemical structure of advanced glycation end-products, and the vulnerability of plaques visualized on MRI scans. MATERIALS AND METHODS: We enrolled 43 patients who had undergone carotid artery stenting (CAS) for carotid artery stenosis; all underwent MRI studies, including black-blood MRI and diffusion-weighted imaging (DWI)...

Background Emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy is a routine procedure. Yet, precise indications and clinical safety in this setting remains controversial. Present data for mechanical thrombectomy include few studies with acute stenting of tandem occlusions. We evaluated the feasibility, safety and clinical outcome of this endovascular treatment in a retrospective analysis of all consecutive cases at a comprehensive stroke centre...

BACKGROUND AND PURPOSE: Intracranial atherosclerosis is a common cause of ischemic stroke. Intracranial stenosis is most commonly quantified by the Warfarin-Aspirin Symptomatic Intracranial Disease method, which involves calculating a ratio of luminal diameter measurements on conventional angiography. Our purpose was to determine whether a single linear measurement of the narrowest caliber of the intracranial ICA on MRA can accurately predict Warfarin-Aspirin Symptomatic Intracranial Disease stenosis measurements...

OBJECTIVE: To report the prevalence of Silent Brain Infarcts (SBI) at MRI before and after surgery for asymptomatic high grade carotid stenosis. DESIGN: Single-center retrospective observational study METHODS: Asymptomatic patients who underwent carotid endarterectomy between October 2012 and October 2014 were included. The preoperative assessment included a Doppler and a CT scan dating less than 3 months. A neurological examination was performed during the anesthesia consultation and in the 15 days before surgery...

OBJECTIVES: Doppler ultrasound (US) has been widely used to evaluate the cervical venous system of multiple sclerosis (MS) patients according to the hypothesis of chronic cerebrospinal venous insufficiency (CCSVI) with contradictory results. Venous anatomy and pathology can be examined with less operator-dependent magnetic resonance imaging (MRI). DESIGN: To assess the inter-observer agreement in measuring internal jugular vein (IJV) cross-sectional area (CSA) in MR-images and to explore the agreement between US and MRI in the detection of calibres of ≤ 0...

BACKGROUND: Patients (pts) scheduled for coronary artery bypass grafting, burdened with high risk of carotid stenosis, are recommended to undergo duplex ultrasonography (DUS) of carotid arteries. PURPOSE: To validate pocket-size imaging device (PSID) equipped with linear probe as an easily accessible tool enabling bedside screening for carotid artery stenosis (CAS). METHODS: A total of 100 pts (60 men, mean age 69±11 years) with multivessel coronary artery disease underwent bedside DUS of carotid arteries with the use of PSID performed by a cardiology resident trained in DUS...

OBJECTIVE This article describes the use of ultrasound measurements of physical strain within carotid atherosclerotic plaques as a measure of instability and the potential for vascular cognitive decline, microemboli, and white matter changes. METHODS Asymptomatic patients with significant (> 60%) carotid artery stenosis were studied for dynamic measures of plaque instability, presence of microemboli, white matter changes, and vascular cognitive decline in comparison with normative controls and premorbid state...

BACKGROUND AND PURPOSE: Up to 50% of ischaemic strokes in young adults are classified as cryptogenic despite extensive work-up. We sought to evaluate the prevalence of non-obstructive carotid atherosclerosis (NOCA) and its association with patent foramen ovale (PFO) in young adults with cryptogenic stroke (CS). METHODS: Patients aged 18-54 years, consecutively treated for first-ever CS in an academic stroke service, were included. NOCA was assessed using carotid ultrasound examination and was defined as carotid plaque with <50% stenosis...
