Large vessel occlusive disease portends a poor prognosis unless recanalization is rapidly achieved. It maneuvers atraumatically, providing improved distal intracranial support for a variety of complex cerebrovascular interventions and preserves necessary ID for quality intraprocedural roadmaps and angiography. A leading journal selection tool is available free of charge for authors to find the best fit for their manuscript. Materials and methods Patients treated with flow diverters between January 2009 and January 2013 followed by MRA at 3 T (3D-TOF-MRA and CE-MRA) and DSA within a 48 h period were included in a prospective single-center study. The device proved technically easy to deploy and recapture after partial deployment if needed. Rather, the incidence of stroke increased, and the events were noted to occur sooner than with medical therapy alone. The primary outcome measures were 30 day stroke and death, and in most cases 30 day myocardial infarction (MI) also. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values. Journal of NeuroInterventional Surgery. The Journal of NeuroInterventional Surgery (JNIS) aims to be the leading peer review journal for scientific research and literature pertaining to the field of neurointerventional surgery. Duration of levetiracetam prophylaxis ranged from 1 day to 6 weeks following SAH (mean 13.2; median 11). Results: Cases of reversible vasculopathy have also been reported in menopausal women. Thus it can pose significant therapeutic challenges. The development of techniques and materials in endovascular, radiosurgical, and neurosurgical fields led to higher rates of complete occlusions and good clinical outcomes. Thromboembolic events are common after stent-assisted coiling with an incidence comparable to DWI studies after coiling alone. Methods: Diffusion-weighted MRI (DWI) can be used for detection of these lesions. Ratio of a journal's items, grouped in three years windows, that have been cited at least once vs. those not cited during the following year. Data Source: Scopus®, Metrics based on Scopus® data as of April 2020. We also review the embryonic development and the clinical significance of this anomaly. This is the Citationsy guide to Journal of NeuroInterventional surgery citations, reference lists, in-text citations, and bibliographies. The Journal of NeuroInterventional Surgery (JNIS) is a Plan S compliant Transformative Journal. The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. This journal is particularly interested in addressing common diseases and their treatment, or illuminating mechanisms of disease or modes of action of treatments, whether related to their efficacy or their complications. All patients treated with the Wingspan stent in a single academic center from January 2006 to February 2008 were identified. Transcervical access for acute ischemic stroke leads to rapid and high quality recanalization. Tandem proximal and distal occlusions in the setting of an acute stroke are therapeutic challenges. Conclusions RNI following IATT for stroke is more likely when at least two of the following are present: good reperfusion, good pial collateral formation and treatment within 4.5 h of symptom onset, and is strongly predictive of 3 month outcomes. The hormonal and physiologic changes that take place during the postpartum period and menopause may not be very different from those that occur after a hysterectomy and oophorectomy. Methods: The Thrombolysis In Myocardial Infarction (TIMI) 2 or 3 revascularization rate was 91% compared with a reported 82% in the Penumbra Pivotal trial. 3D-DSA is the 'gold standard' imaging technique for the diagnosis and characterization of intracranial aneurysms. Conclusions: Eleven of the 34 aneurysms (32.3%) were treated with a Y-stent configuration. In post-procedural DWI, 48 of the 75 patients (64%) had 163 DWI lesions in a pattern consistent with embolic events. Endovascular therapy is frequently the method of treatment in such situations but there remains a chance of incomplete recanalization. BMJ Neurology Open is an online, peer-reviewed, open access journal, dedicated to publishing research in all areas of clinical neurology and neuroscience. Conclusions: Our initial clinical experience with the FRED system is described. Only one patient had disability at the 3 month follow-up that was possibly related to the stent (mRS score of 3 and NIHSS score of 2). JNIS is a leading peer review journal for scientific research and literature pertaining to the field of neurointerventional surgery. The routine use of seizure prophylaxis following aSAH is controversial. The median age was 66 years and the median NIH Stroke Scale score was 17. The Journal of NeuroInterventional Surgery is a peer-reviewed medical journal covering the field of neurointerventional surgery.It is published by the BMJ Group on behalf of the Society of NeuroInterventional Surgery.It is also the official journal of the Interventional Chapter of the Australian and New Zealand Society of Neuroradiology. Primary MAT is an alternative endovascular recanalization technique with reasonable first pass efficacy that will likely improve with technology and experience. Conclusions: The objective of this study was to determine current practices regarding seizure prophylaxis in aneurysmal subarachnoid hemorrhage (aSAH).

Since 2002, the SGR has annually recommended reductions in Medicare reimbursements. Background and purpose: One stroke occurred after the first 30 days, suggesting a significant stabilization of the adverse event rate after the first month. Variations of the A1 segment occurred significantly more frequently in the aneurysm group than in the control group. We have employed a treatment approach that uses both complete proximal occlusion and reversal of flow in the ipsilateral A1 segment, using different endovascular modalities such as coils, stent-assisted coiling, or flow diverters (FDs) plus coiling concomitantly. Primary outcomes were those patients receiving treatment and the ratio of untreated to treated aneurysms per state. Immediate angiographic results were categorized according to the pattern of extra-aneurysmal Onyx leakage: grade A, none; grade B, 'hat brim' lamination; and grade C, 'ectopic' Onyx (C1, non-flow limiting; C2, flow limiting). A retrospective analysis was performed of 32 cases comprising 34 aneurysms in which the LVIS Jr device was used for stent-assisted coil embolization of intracranial aneurysms from February to October 2012, including all clinical and angiographic data as well as mid-term follow-up (1-12 months of treatment). Results Greater than 50% reperfusion of the involved territory, time to treatment within 270 min and good pial collateral formation (large penumbra zone) significantly predicted RNI. At 1 month follow-up, the patient had no complaints and showed complete resolution of all oculomotor symptoms. Referencing books, youtube videos, websites, articles, journals, podcasts, images, videos, or music in Journal of NeuroInterventional surgery. Direct carotid artery puncture is a feasible alternative to transfemoral artery access in cases of stroke with difficult anatomy, including unfavorable arch type, carotid tortuosity, or an ostial lesion. In addition, a systematic review of the literature is presented describing previous experience with HPC of the cervical region. The other two were treated with a FD. Methods: These catheters must accommodate 0.027 inch microcatheters, be supple enough to track distally and be able to provide sufficient support for manipulations required for PED deployment. The aneurysm was deemed treatable by endovascular coil embolization and the patient underwent successful placement of a detachable helical coil. Angiographic recurrence was observed in four cases (16.7%), all grade A (p=0.006). No significant catheter-related complications occurred. Mean age of the sample was 67 years, and 54% were women. Conclusions: Aneurysm occlusion was assessed with full and simplified Montreal scales and parent artery patency with three-grade and two-grade scales. Immediate total occlusion was observed in 16/34 (47%), near total occlusion (90-95%) in 5/34 (14.7%) and a 'dog ear' or subtotal occlusion in 12/34 (35.2%). This simple grading system may help predict long term angiographic results. Background: Individual Rates: Personal subscription orders can only be placed by individuals and must include the recipient's name and personal address. Future studies will focus on improved hemostasis and early identification of patients who would benefit the most from direct carotid access for acute stroke. Absolutely nothing? The frequency of any stroke or death within 30 days or ipsilateral stroke beyond 30 days was 5/51 (10.0%) at a mean follow-up time of 14.6 months (range 8-30). The users of Scimago Journal & Country Rank have the possibility to dialogue through comments linked to a specific journal. Journal of Neurology, Neurosurgery and Psychiatry is a Plan S compliant Transformative Journal.. Journal of Neurology, Neurosurgery and Psychiatry (JNNP)'s ambition is to publish the most ground-breaking and cutting-edge research from around the world. An embolic protection device was deployed through the intermediate catheter which was subsequently removed. Three interventional neuroradiologists measured two dimensions of each aneurysm for all protocols. Vertebral artery origin anomalies are typically incidental findings during angiography or post mortem examination. When I first saw the title of the article by Choulakian, Drazin and Alexander1 in the December 2010 JNIS, I thought that I had misread it. Conclusions At 3 T, CE-MRA is superior to 3D-TOF-MRA for the evaluation of aneurysm occlusion and parent artery patency after flow diversion treatment. Results Twenty-two patients harboring 23 treated aneurysms were included. The Institute of Medicine called attention to the pervasive differences in treatments and outcomes between ethnic groups. In each case the catheter was tracked to its desired position (100% clinical success) despite significant proximal vessel tortuosity in 34 cases (44%). Methods: The Navien intracranial catheter is an important component of the triaxial system for embolization of cerebral aneurysms with the PED. We retrospectively reviewed all neurointerventions performed by the senior author during an 18-month period to identify patients in whom the Navien intracranial catheter was placed in an ultra-distal position, defined as beyond the clinoidal internal carotid artery (ICA) or V3 segment of the vertebral artery. The Journal of NeuroInterventional Surgery is a Plan S compliant Transformative Journal. The mechanisms involved in the development of this condition are explained by current research concerning effects on the vasculature of sudden drops in estrogens and progesterones. Progression of ISR after 6-12 months is uncommon over a 2-3 year period. Primary MAT was carried out with a preference for the largest catheter considered to be trackable into the target occlusive lesion. Demographic data, aneurysm characteristics and angiographic parameters were correlated with properties of DWI lesions. Onyx HD-500 embolization of intracranial aneurysms leads to high rates of complete and durable occlusion. This technique may facilitate the use of new stent technologies in the treatment of large aneurysms that have traditionally been exceedingly difficult to treat via an endovascular approach. We illustrate two strategies for using 4 F and 5 F systems for interventions in a manner that enables such techniques as balloon assisted coil embolization and the deployment of triaxial catheter systems to be used. I went on to read, with dismay, the description of treatment of what most commonly should be regarded as ‘do not touch’ lesions. The Journal of NeuroInterventional Surgery™ (JNIS) is the leading peer-reviewed journal for scientific research and literature pertaining to the field of neurointerventional surgery. Measurements included packing density, number of coils per unit aneurysm volume, and total coil length per unit aneurysm volume. There was one MI. The chart shows the ratio of a journal's documents signed by researchers from more than one country; that is including more than one country address. The latest citescore of Journal of NeuroInterventional Surgery is 2.98.CiteScore is a new standard that gives a more comprehensive, transparent and current view of a journal’s impact that will help you guide your journal more effectively in the future. CE-MRA yielded better accuracy than 3D-TOF-MRA for aneurysm remnant detection (sensitivity 83% vs 50%; specificity 100% vs 100%) and for the status of the parent artery (specificity 63% vs 32%; sensitivity 100% vs 100%). Intraprocedural Navien positions were as follows: supraclinoid ICA (n=2); mid M1 (n=1); V3-V4 junction (n=2) (both using 6 F Navien); distal V4 (n=3); proximal basilar (n=1); proximal-mid basilar (n=1); mid basilar (n=1). In fact, I am not a regular reader of your journal. For topics on particular articles, maintain the dialogue through the usual channels with your editor. The flow redirection endoluminal device (FRED; Microvention, Tustin, California, USA) system is a next generation closed cell paired stent flow diversion device. Further studies are necessary to improve the safety of stent-assisted coiling for patients in conditions with increased risk potential (age, procedure time, stent length). Rates of facilitated endogenous recanalization at 24 h (FER(24)) were compared by imaging within the immediate post-intervention 5-24 h period in those with proximal recanalization and in those without. Our primary outcomes were ischemic stroke related to the stent and bleeding complications possibly related to antithrombotic therapy. International Collaboration accounts for the articles that have been produced by researchers from several countries. Stable angiographic results were seen in 85%, 94%, 94%, and 100% at 6, 12, 24, and 36 months, respectively. Two patients had asymptomatic occlusions at 6 months (0.8%). The aim of the present study was to investigate the incidence of DWI lesions after stent-assisted coiling and the evaluation of possible risk factors. The Penumbra 054 catheter may be used both to aspirate the distal thrombus and to house the embolic protection device as it is advanced past a proximal occlusion. Restricting groin access to 4 F and 5 F systems constrains the range of procedures that can potentially be performed. The ischemic brain volume was significantly increased in older patients (≥55 years) as well as in patients who were implanted with a shorter stent (<20 mm). The case of a 61-year-old woman is reported who presented with a 7 month history of dizziness, mild ataxia and left-sided tinnitus when supine. In a 41-year-old woman with a ruptured anterior communicating artery aneurysm, cerebral angiography incidentally showed an absence of the right common carotid artery. Radiographic visibility and ability to maintain its internal cylindrical shape in tortuous arteries, as demonstrated by fluoro CT, was at least as good as the pipeline embolization device. 17 patients were included in the analysis. Acute, simultaneous, concomitant internal carotid artery (ICA) and middle cerebral arteries (MCA) occlusions almost invariably lead to significant neurological disability if left untreated. Neurointerventional surgery is a multi-disciplinary Accreditation Council for Graduate Medical Education (ACGME) accredited and American Medical Association (AMA) recognized medical specialty specializing in minimally invasive image-guided procedures to treat disorders of the brain, head/neck, and spine. Complete occlusion was achieved in 27/84 patients (32.2%), in 40/84 (47.6%) brain AVMs occlusion of 80-90% of the nidus was obtained, and in 17/84 (20.3%) cases <80% of the nidus was occluded. Interventional Neuroradiology (INR) is a peer-reviewed clinical practice journal documenting the current state of interventional neuroradiology worldwide. Aneurysm occlusion rates were similar in both groups. This study compares the diagnostic accuracy of three-dimensional time-of-flight MR angiography (3D-TOF-MRA) and contrast-enhanced MRA (CE-MRA) at 3 T for the evaluation of aneurysm occlusion and parent artery patency after flow diversion treatment, with digital subtraction angiography (DSA) as the gold standard. With an average follow-up of 20.7 (range 16-24) months, the mean Visual Analog Scale score for back pain decreased from 8.67 to 0.67 and no patient experienced tumor recurrence. Methods: Large unruptured AVMs (Spetzler-Martin grades IV-V) should be treated with target embolization of high flow fistulas or intranidal aneurysms. Primary MAT was associated with faster procedural times (mean 63 vs 97 min, p<0.0001) but not with higher rates of favorable outcomes. The time course and frequency of moderate and severe ISR in our single institution prospective registry of CAS procedures is reported here. Journal of NeuroInterventional Surgery Publication Information. The Journal of NeuroInterventional Surgery (JNIS) is a leading peer review journal for scientific research and literature pertaining to the field of neurointerventional surgery. Results: Safe deployment through an occluded vessel may be assisted by use of an intermediate catheter. Our objective was to study emergent direct percutaneous carotid artery puncture as an alternative access approach for acute endovascular stroke interventions. Despite the known limitations of this landmark study, the number of EC-IC bypass procedures fell precipitously over the ensuing decades. The number of coils per aneurysm volume of 0.026 coils/mm(3) for the Penumbra coil was significantly lower than 0.114 coils/mm(3) for the Orbit/Galaxy coils. Preoperative embolization with Onyx-18 should be considered for large HPC as it may decrease the risk of intraoperative hemorrhage. * Required. To describe procedural aspects and clinical outcomes in a consecutive series of patients in whom manual aspiration thrombectomy (MAT) was performed as the first treatment modality with other techniques used only in case MAT did not yield recanalization. 24 (96%) respondents agreed that a trial randomizing patients to levetiracetam or no antiseizure medication is warranted at this time, and all 25 (100%) believed that such a trial would be appropriate or ethically sound. All cases of Onyx embolization for unruptured aneurysms performed between September 2008 and April 2010 were retrospectively reviewed. The LVIS Jr device can also be implanted in a Y-stent configuration, offering a novel technique with a potentially lower risk of thromboembolic complications compared with other devices. The Journal of NeuroInterventional Surgery (JNIS) is a leading peer review journal for scientific research and literature pertaining to the field of neurointerventional surgery. We also reviewed current literature relevant to this subject. Mean baseline NIHSS score was 17 and 90 day mRS score was 4. Scientific Journal Selector (2018-2019), we collect latest information of SCI journals, include ISSN, h-index, CiteScore, online submission URL, research area, subject area, submission experience, etc. Intermodality agreement was higher for CE-MRA (0.88 and 0.32) than for 3D-TOF-MRA (0.59 and 0.11). The Journal of the Society of NeuroInterventional Surgery. This catheter is highly trackable to distal positions, atraumatic and provides sufficient support for the microcatheter manipulations used during typical PED deployments. A single aneurysm was treated without coil embolization. To compare the image quality and accuracy of low dose 3D-DSA protocols in patients with unruptured intracranial aneurysms. Conclusions The periprocedural complication rate was higher in ruptured aneurysms than in unruptured aneurysms. Background and purpose Follow-up of intracranial aneurysms treated by flow diverter with MRI is complicated by imaging artifacts produced by these devices. However, intraluminal evaluation remains difficult with MRA regardless of the sequence used. This was a retrospective single operator experience of aneurysm coiling at the Ochsner Clinic, comparing the Penumbra coil 400 with the other most commonly used coil types, Orbit and Galaxy. Favorable outcomes (90-day modified Rankin Scale ≤2) were 46%. PLUS: Download citation style files for your favorite reference manager. The published series of Steibel-Kalish and coworkers3 and Goldenberg-Cohen and coworkers4 were series in which either endovascular parent artery occlusion or surgical bypass was utilized as the treatment strategy, not endosaccular occlusion, as was utilized in our series. Delayed parent vessel occlusion occurred in two cases (8.3%), both grade C2 (p=0.014). 44 aneurysms in 42 patients were treated. Important to clinical management, IATT may need to be reconsidered in patients with poor pial collateral formation if time to treatment exceeds 4.5 h. In-stent restenosis (ISR) is a potentially preventable cause of stroke in carotid artery stent (CAS) patients. Intraprocedural adverse events occurred in 11/84 patients (13.1%), and overall mortality and disabling permanent morbidity were 2.3% (2/84) and 4.7% (4/84), respectively. 12 patients had good initial proximal recanalization but a residual partial or total occlusion of the MCA while five patients failed any recanalization. The absence of the common carotid artery is extremely rare and association with a ruptured cerebral aneurysm is even less common. The opposite was true for lower Charlson Comorbidity Index (OR 3.03, 95% CI 2.71 to 3.39, p<0.0001), coverage by Medicaid (OR 1.12, 95% CI 1.03 to 1.23, p=0.012), or private insurance (OR 1.92, 95% CI 1.80 to 2.04, p<0.0001), and lower income (OR 1.22, 95% CI 1.15 to 1.31, p<0.0001). Evolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years. Stenting and angioplasty were then performed, followed by removal of the embolic protection device which had visibly trapped debris. While oculomotor nerve palsy is an incredibly rare sequelae of anterior cerebral artery aneurysm rupture, it is important that clinicians and researchers continue to report and study such cases. Background Intracranial aneurysms are increasingly treated with endovascular treatment. Not every article in a journal is considered primary research and therefore "citable", this chart shows the ratio of a journal's articles including substantial research (research articles, conference papers and reviews) in three year windows vs. those documents other than research articles, reviews and conference papers. Two patients had asymptomatic intracranial hemorrhages and one patient had a symptomatic intracranial hemorrhage. Among a sampling of 25 major academic centers, most administer prophylaxis, while a significant proportion does not. Embolic protection devices may have a role in the emergency treatment of proximal occlusions in the setting of an acute ischemic stroke. Consequently, since the inception of Medicare programs in 1965, several methods have been used to determine the amounts paid to physicians for each covered service. Successful neuroendovascular treatments rely on microcatheter stability from guide catheter support. Patients with moderate ISR at 6 months did not progress to severe ISR. All-cause mortality was 25.6%. Moreover, anatomic variations of the anterior cerebral artery (ACA) seem to correspond to the prevalence of aneurysms in the anterior communicating artery (ACoA). pmRFA of spinal osteoid osteomas is feasible, even when the tumor is abutting the spinal canal. Find out more about Transformative Journals and Plan S compliance on our Author Hub. The journal launch addressed growing professional interest in neurointerventional techniques for the treatment of a range of neurological and vascular problems including stroke, aneurysms, brain tumors, and spinal disorders. Over the ensuing years, JNIS flourished and has published a considerable number of high-profile articles. Understanding the frequency and timing of ISR would be useful in developing optimal protocols for carotid stent surveillance. The HDE: what is it good for? SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from Post-deployment angiography and fluoro CTs were obtained in all cases.
