INTRODUCTION: The value of simulation in medical education and procedural skills training is well recognized. Despite this, many mannequin-based trainers are limited by the inability of the trainee to view the internal anatomical structures. This study evaluates the usability and feasibility of a first-person point-of-view-augmented reality (AR) trainer on needle insertion as a component of central venous catheter placement. METHODS: Forty subjects, including medical students and anesthesiology residents and faculty, participated...

BACKGROUND: When an internal carotid artery (ICA) occludes, a patient may develop cerebral infarction (CI). We investigated whether CI caused by ICA occlusion (ICAO) is associated with collateral flow through the anterior and posterior communicating arteries (ACoA and PCoA). METHODS: In 100 patients with ICAO, we investigated CI and white matter disease by performing an MRI and the anatomy of the ACoA and PCoA were investigated by performing magnetic resonance angiography...

BACKGROUND AND PURPOSE: In 2006, the American Heart Association recommended that carotid revascularization generally occurs within 2 weeks of stroke based on data from 2 trials of carotid endarterectomy (CEA). We aimed to determine whether the time between stroke and CEA or carotid artery stenting (CAS) has decreased and whether the proportion of procedures occurring within 14 days has increased. METHODS: Using validated International Classification of Diseases, Ninth Revision, Clinical Modification codes and administrative claims data from nonfederal hospitals in CA, FL, and NY, we identified patients with ischemic stroke who underwent CEA or CAS within 90 days of an ischemic stroke from 2005 to 2013...

BACKGROUND: The goal of the treatment of direct carotid cavernous fistula (CCF) is to occlude the arteriovenous shunt and to preserve the patency of the concerned internal carotid artery (ICA). However, for the ipsilateral post-traumatic fragile cerebrum, coil embolization plus parent artery occlusion for the high flow direct CCF would be better for the prevention of hyper-perfusion syndrome and the intracranial hemorrhage. We experienced such a case and managed it successfully. CASE DESCRIPTION: A 6-year-old boy was suffered from severe head trauma caused by being hit by a car...

Acute ischemic stroke (AIS) is the leading cause of premature mortality and morbidity worldwide for both men and women. Extracranial carotid artery stenosis/occlusion is responsible for approximately 11.5%% of ischemic strokes, whereas extracranial large vessel disease comprises roughly 16.6% of ischemic strokes. Carotid artery disease has been the source of significant debate among neurovascular and cardiovascular specialists, as well as vascular surgeons, as to the best method of revascularization, surgical reconstruction versus endovascular recanalization...

We investigated whether type 2 diabetes (T2DM) and the presence of cognitive impairment are associated with altered cerebral blood flow (CBF). Forty-one participants with and thirty-nine without T2DM underwent 3-Tesla MRI, including a quantitative technique measuring (macrovascular) blood flow in the internal carotid artery and an arterial spin labeling technique measuring (microvascular) perfusion in the grey matter (GM). Three analysis methods were used to quantify the CBF: a region of interest analysis, a voxel-based statistical parametric mapping technique, and a 'distributed deviating voxels' method...

INTRODUCTION: Single stent deployment leads to a change in vascular geometry in wide necked bifurcation aneurysms. In some complex cases, the use of the single stent technique might not be sufficient or may not be feasible. The kissing-Y stenting technique appears to be an alternative endovascular treatment option. The aim of this study was to evaluate the effects of the kissing-Y stenting technique on vascular angular remodeling. METHODS: 21 patients with wide necked intracranial bifurcation aneurysms at different sites (10 anterior communicating artery, 6 middle cerebral artery, 3 basilar artery, 1 vertebral artery/posterior inferior cerebellar artery, 1 internal carotid artery/posterior communicating artery) were treated with 44 closed cell stents (follow-up 2012-2016) using the kissing-Y stenting technique...

Graves disease is rarely complicated with cerebrovascular steno-occlusive diseases. Previous studies have suggested several hypotheses for this occurrence, including excess thyroid hormone, which stimulates the sympathetic nervous system, which in turn causes an abnormal hemodynamic response with consequent atherosclerotic changes, and antithyroid antibodies cause local vascular inflammation in patients with Graves disease. However, radiological findings of vasculitis in patients with Graves disease and cerebral infarction remain less known...

BACKGROUND: Intracranial carotid sympathetic plexus schwannoma (CSPS) is extremely rare; thus differential diagnostic criteria, optimal surgical strategies, and even a precise definition are lacking. Here we describe a case of CSPS and propose a definition and classification for previously reported cases. CASE DESCRIPTION: A 54-year-old male presented with hypacusis and abducens nerve palsy. Radiological examinations revealed a well-enhanced mass at the right medial temporal base with erosion of the petrous apex and intact perilesional cortical bone...

OBJECTIVE: The best management of carotid artery dissection (CAD) is still controversial ranging from antiplatelet medication to open surgery or endovascular treatment. In this retrospective study we assessed the safety and efficacy of endovascular stent angioplasty for the treatment of CAD. METHODS: From February 2006 to February 2016, 44 patients (28 females and 16 males, age range 25-65 years, mean 42) with CAD were included in this study. The internal carotid artery (ICA) dissection was spontaneous in origin in 32 patients and post-traumatic in the remaining 12 (1 case it was bilateral)...

Bone mineral density (BMD) has been suggested to be associated with atherosclerosis. In the present study, we evaluated the association between lumbar BMD and the segments of carotid intima-media thickness (CIMT), a surrogate marker of subclinical atherosclerosis, in Korean adults, with consideration of sex and menopause status. Among 1,679 Korean adults who enrolled in a Healthy Twin Study, 723 men, 690 premenopausal women, and 266 postmenopausal women measured the CIMT at the common carotid artery intima-media thickness (CCA-IMT), carotid bifurcation intima-media thickness (BIF-IMT), internal carotid artery intima-media thickness (ICA-IMT) using B-mode ultrasound and lumbar BMD using dual-energy X-ray absorptiometry...
