BACKGROUND: Recent observations have suggested a decline in vulnerable carotid artery and iliofemoral atherosclerotic plaque characteristics over the past decade. The aim of this study was to determine whether, in the presence of clinically manifest carotid or peripheral artery disease, secondary adverse cardiovascular events decreased over this period. METHODS: Patients included in the Athero-Express biobank between 2003 and 2012 were analysed. During 3-year follow-up, composite cardiovascular endpoints were documented yearly, including: myocardial infarction, coronary interventions, stroke, peripheral interventions and cardiovascular death...

BACKGROUND AND PURPOSE: Randomized controlled trials have shown that bridging endovascular therapy (EVT) after intravenous thrombolysis (IVT) therapy improves outcome in patients with stroke with large-artery anterior circulation stroke compared with IVT alone. It remains unknown whether IVT adds any benefit to EVT in these patients. The aim of this study was to assess recanalization rates and thrombus dislocation before initiation of EVT in patients receiving bridging therapy. METHODS: All patients in the Bernese stroke registry (2008-2015) in whom bridging therapy was considered were included in this analysis...

Dissections of extracranial arteries are estimated to account for only 2% of all ischemic strokes but for approximately 20% of strokes in patients younger than 45 years old. Most dissections of extracranial arteries involve some trauma stretch, mechanical stress, or connective tissue abnormalities. In the absence of these disorders, determining the etiology of recurrent extracranial dissections is quite challenging because the underlying nature of these cases is poorly understood. We report the case of a 44-year-old female with recurrent dissections of the vertebral and carotid arteries associated with a heterozygous mutation p...

BACKGROUND: Despite recent improvements in angioplasty and placement of drug-eluting stents in treatment of atherosclerosis, restenosis and in-stent thrombosis impede treatment efficacy and cause numerous deaths. Research efforts are needed to identify new molecular targets for blocking restenosis. We aim to establish angiogenic factor AGGF1 (angiogenic factor with G patch and FHA domains 1) as a novel target for blocking neointimal formation and restenosis after vascular injury. METHODS AND RESULTS: AGGF1 shows strong expression in carotid arteries; however, its expression is markedly decreased in arteries after vascular injury...

BACKGROUND: The Rice-Vannucci model of hypoxic-ischaemic encephalopathy (HIE) has been associated with a high degree of variability with respect to the development of cerebral infarction and infarct lesion volume. For this reason, we examined the occurrence of communicational blood flow within the common carotid (CCA), internal (ICA), and external (ECA) carotid arteries following CCA occlusion as a source of variability in the model. NEW METHOD: We propose a novel modification to the Rice-Vannucci model, whereby both the CCA and ECA are permanently ligated; mitigating communicational blood flow...

BACKGROUND: Recent technological developments allowed significant improvements in interventional approach to carotid artery stenosis. Tapered stents were specifically designed for extracranial carotid artery stenting (CAS) to deal with vessels mismatch with the objective of decreasing the risk of thrombosis. Nevertheless, whether the stent geometry may affect the outcomes of CAS is uncertain. This study aims to investigate the impact of stent configuration on perioperative and long term results of this procedure...

OBJECTIVE: Identification of patients with high-risk asymptomatic carotid plaques remains an elusive but essential step in stroke prevention. Inflammation is a key process in plaque destabilization and a prelude to clinical sequelae. There are currently no clinical imaging tools to assess the inflammatory activity within plaques. This study characterized inflammation in atherosclerosis using dual-targeted microparticles of iron oxide (DT-MPIO) as a magnetic resonance imaging (MRI) probe...

Osthole (7-methoxy-8-isopentenoxy-coumarin), a compound extracted from Cnidiummonnieri (L.) Cusson seeds, has been found to exhibit potent therapeutic effects in cancer due to its ability to inhibit inflammation and cell proliferation. However, its effects on arterial wall hypertrophy-related diseases remain unclear. Therefore, in this study, we aimed to investigate the effects of Osthole on intimal hyperplasia in a rat model of carotid artery balloon injury. We established the balloon-induced carotid artery injury rat model in male Sprague-Dawley rats, after which we administered Osthole (20mg/kg/day or 40mg/kg/day) or volume-matched normal saline orally by gavage for 14 consecutive days...

Down syndrome is a frequent clinical entity, being considered one of the most frequent chromosomal aberrations. It is characterised by a typical clinical phenotype and is associated with a heterogeneous group of organ and system-specific abnormalities. The cardiovascular system is commonly affected and if so, it may be associated with an increased morbidity and mortality. Cerebrovascular events in patients with Down syndrome are multifactorial, being possibly related to congenital heart disease, vascular malformations and traditional cardiovascular risk factors...

Rapid, safe and effective arterial recanalisation to restore blood flow and improve functional outcome remains the primary goal of hyperacute ischaemic stroke management. The benefit of intravenous thrombolysis with recombinant tissue-type plasminogen activator for patients with severe stroke due to large artery occlusion is limited; early recanalisation is generally less than 30% for carotid, proximal middle cerebral artery or basilar artery occlusion. Since November 2014, nine positive randomised controlled trials of mechanical thrombectomy for large vessel occlusion in the anterior circulation have led to a revolution in the care of patients with acute ischaemic stroke...

BACKGROUND: There is a need to identify sensitive biomarkers of early tobacco-related cardiovascular disease. We examined the association of smoking status, burden, time since quitting, and intensity, with markers of inflammation and subclinical atherosclerosis. METHODS AND RESULTS: We studied 14 103 participants without clinical cardiovascular disease in ELSA-Brasil (Brazilian Longitudinal Study of Adult Health). We evaluated baseline cross-sectional associations between smoking parameters and inflammation (high-sensitivity C-reactive protein [hsCRP]) and measures of subclinical atherosclerosis (carotid intima-media thickness, ankle-brachial index, and coronary artery calcium [CAC])...

BACKGROUND: Direct carotid-cavernous sinus fistulas (CCF) are high flow arteriovenous shunts that are typically the result of a severe head injury. The endovascular treatment of these lesions includes the use of detachable balloons, coils, liquid embolic agents, and covered stents. To minimize the chance of treatment failure and subsequent complications, endoluminal reconstruction using a flow-diverting stent may be added to the treatment construct . METHODS: We present 3 cases and review the existing literature...

OBJECTIVES: The impact of left subclavian artery (LSA) revascularization prior to thoracic endovascular aortic repair (TEVAR) on cerebrovascular flow is not well described. We studied bilateral vertebral and carotid artery flow characteristics before and after TEVAR, to evaluate the hemodynamic effects of LSA revascularization. METHODS: Seventy-four patients with mixed etiologies (mean age 70.9±10.5 years) underwent LSA revascularization and TEVAR (2006-2016) and had available pre- and post-operative carotid Duplex study available...

We present a series of 4 patients with carotid restenosis following carotid endarterectomy (CEA) who underwent transcervical carotid artery stenting (CAS) using a novel prosthetic conduit technique. The patients were high risk for repeat CEA (short and obese necks) and had contraindications to transfemoral CAS (Bovine arch, prior dissection). Carotid artery stenting was thus performed via a transcervical approach with a polytetrafluoroethylene (PTFE) conduit anastomosed to the proximal common carotid artery (CCA)...

Hypoxic-ischemic (HI) brain injury in newborns is associated with high morbidity and mortality, with many babies suffering neurological deficits. Recently, we showed that hypoxic postconditioning (PostC) immediately post injury can protect against HI up to one week in neonatal rats. Here, we aimed to examine whether long term functional deficits were also improved by PostC. Sprague-Dawley rats were assigned to control (C) or HI group on postnatal day 7 (P7). The HI group underwent unilateral carotid artery occlusion followed by hypoxia (7% oxygen, 3h)...

BACKGROUND AND PURPOSE: Small studies have suggested that Ehlers-Danlos syndrome (EDS) is associated with a number of cerebrovascular complications. We sought to determine whether a clinical diagnosis of EDS is associated with a higher prevalence of cerebrovascular diseases than the general population by performing a case-control study of hospitalized patients in the Nationwide Inpatient Sample (NIS). METHODS: Using the 2000-2012 NIS, we performed a case-control study matching cases of EDS to controls without such a diagnosis...

BACKGROUND: The incidence of Blunt Carotid Artery and Vertebral Artery Injury (BCVI) is relatively low in modern trauma practice. However, these injuries may be associated with severe neurological consequences. Following the introduction of a Diagnostic Imaging Pathway in Department of Health of Western Australia, we hypothesized that this injury would be less likely to be missed, and accordingly diagnosed more frequently. METHOD: A review of all major trauma (Injury Severity Scale>15) admissions at the State Major Trauma Centre in Royal Perth Hospital was undertaken from 1995 until 2013...
