It is estimated that approximately 30% of ischemic strokes are caused by rupture of plaque in the carotid artery. Development of techniques focusing on identifying plaques that are vulnerable to rupture is thus indispensable for stroke prevention. Recent studies have demonstrated that motion analysis of plaques from B-mode and RF ultrasound (US) image sequences can be used to estimate plaque strain. However, viability of these methods in a clinical setting, with variable acquisition protocols, has not been demonstrated yet...

BACKGROUND: Carotid-femoral pulse-wave velocity (cf-PWV) and brachial-ankle PWV (ba-PWV) are the 2 most frequently applied PWV measurements. However, little is known about the comparison of hypertensive target organ damage (TOD) with cf-PWV and ba-PWV. METHODS AND RESULTS: A total of 1599 community-dwelling elderly subjects (age >65 years) in northern Shanghai were recruited from June 2014 to August 2015. Both cf-PWV and ba-PWV were measured using SphygmoCor and VP1000 systems, respectively...

Spontaneous chronic subdural hematoma (CSH) in infants is extremely rare. A very limited number of cases are known and reported in literature. The clinical presentation can be myriad varying from asymptomatic cases to gross neurological deficits. We report a case of a 3-month-old child who presented to us with repeated episodes of focal seizures of the left upper and lower limb of 1 month duration. Subsequent imaging revealed bilateral CSH (right > left) with left internal carotid artery infarct and midline shift to left by 8 mm...

OBJECTIVE: Despite multiple landmark clinical trials, little data exists on real-world cost of carotid artery stenting (CAS) and carotid endarterectomy (CEA) to the United States healthcare system. We aim to study differences in actual hospitalization cost between patients who underwent CAS vs CEA in a nationally representative database. METHODS: We studied hospital discharge and billing records of all patients, in the Premier Perspective Database, who underwent CEA or CAS between the third quarter of 2009 and the first quarter of 2015...

Though the variations of vertebral artery are clinically asymptomatic yet abnormalities are of diagnostic importance either prior to vascular surgery in the neck region or in patients of intravascular diseases such as arteriovenous malformations or cerebral aneurysms. Therefore, the aim of the study is to bring out 2 variations in the configuration of vertebral artery and their clinical implication. During dissection of thorax of 2 female cadavers, 2 different variants of configurations of left vertebral arteries were observed...

INTRODUCTION: The number of patients receiving chronic dialysis treatment in Japan currently exceeds 300,000 people. Few reports have described carotid endarterectomy(CEA)for chronic renal failure patients because of the unacceptable rate of perioperative stroke and other morbidities. A strategy for and treatment results of CEA for chronic renal failure patients in our hospital are described herein. METHODS: The present study included 6 patients who underwent CEA while receiving dialysis treatment between April 2011 and November 2014...

OBJECTIVE: In-stent restenosis is a recognized complication of carotid angioplasty and stenting (CAS), and it is associated with an increased risk of stroke. Few case series have reported outcomes separately following carotid endarterectomy (CEA) and CAS for the treatment of in-stent restenosis. In this study, we perform an evaluation of redo-CAS vs CEA in a large contemporary cohort of patients who underwent prior ipsilateral CAS. METHODS: We studied all patients in the Vascular Quality Initiative (VQI) database, who underwent CEA or CAS between January 1, 2003, and April 30, 2016, after prior ipsilateral CAS...

OBJECTIVE: Randomized trials support carotid endarterectomy (CEA) in asymptomatic patients with ≥60% internal carotid artery (ICA) stenosis. The widely referenced Society for Radiologists in Ultrasound Consensus Statement on carotid duplex ultrasound (CDUS) imaging indicates that an ICA peak systolic velocity (PSV) ≥230 cm/s corresponds to a ≥70% ICA stenosis, leading to the potential conclusion that asymptomatic patients with an ICA PSV ≥230 cm/s would benefit from CEA. Our goal was to determine the natural history stroke risk of asymptomatic patients who might have undergone CEA based on consensus statement PSV of ≥230 cm/s but instead were treated medically based on more conservative CDUS imaging criteria...

BACKGROUND: Chromogranin A (CgA), a circulating protein released by the neuroendocrine system, can regulate vascular physiology and angiogenesis. Full-length CgA (CgA1-439) and its fragment CgA1-76 (called vasostatin-1, VS-1) preserve the physiological integrity of the endothelial barrier function and are antiangiogenic, whereas CgA1-373 is proangiogenic. We investigated whether these polypeptides are altered in patients with various degrees of carotid artery atherosclerosis. METHODS: We studied 81 patients with carotid artery atherosclerosis, asymptomatic for cerebrovascular diseases...

AIMS: Routine screening of carotid atherosclerosis lesions is frequently suggested for people with type 2 diabetes, the presence of a carotid lesion being associated with a significant increase risk for vascular events. However, the impact of this strategy on medical management is not validated. We herein question the usefulness of such screening. METHODS: We assessed the prevalence and severity of carotid lesions in 337 consecutive people with type 2 diabetes without known cardiovascular disease who underwent a systematic carotid duplex ultrasonography...

Carotid endarterectomy (CEA) carries a significant risk of procedural stroke and death Guidelines recommend keeping this risk below 6% and below 3% for symptomatic and asymptomatic patients respectively. After analysing our Institute's CEA results during the past 25 years, we found the rate of postoperative complications was now well below Guideline thresholds. Accordingly, we studied temporal changes in procedural risks in randomized controlled trials (RCTs) and in large observational studies in order to compare these against Guidelines...

PURPOSE: To evaluate in a proof-of-concept study the feasibility of Simultaneous Noncontrast Angiography and intraPlaque hemorrhage (SNAP) imaging as a clinical magnetic resonance angiography (MRA) technique for measuring carotid stenosis. There is a growing interest in detecting intraplaque hemorrhage (IPH) during the clinical management of carotid disease, yet luminal stenosis has remained indispensable during clinical decision-making. SNAP imaging has been proposed as a novel IPH imaging technique that provides carotid MRA with no added scan time...
