journal of neurointerventional surgery

All occlusions were in the left MCA. RNI occurred in 31% of the 112 patients studied. The Journal of the Society of NeuroInterventional Surgery. Immediate post-treatment angiography demonstrated reduced flow into all aneurysms although no long term angiographic data are yet available. Results: Background/objective: Revascularization of acute ischemic stroke from a large vessel occlusion continues to be a challenge with current thrombectomy devices. Females of childbearing age are most commonly affected with RCVS. We also review the embryonic development and the clinical significance of this anomaly. Conclusions: Angiographic recurrence was observed in four cases (16.7%), all grade A (p=0.006). The primary outcome measures were 30 day stroke and death, and in most cases 30 day myocardial infarction (MI) also. 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. The use of the Wingspan stent in patients with ≥50% symptomatic intracranial stenosis is associated with good long term clinical outcome. In this technique, an over-the-wire balloon was inflated in the distal vessel followed by gentle retraction of the balloon catheter and microwire allowed only a wire bridge across the aneurysm neck, thereby allowing the stent catheter to be brought up in a standard fashion. The median age of the patients was 54 years (range 21-76) and 19 (59%) were women. We appreciate the comments of Dr Hartman1 regarding our series of cavernous carotid aneurysms treated by endosaccular embolization therapy.2 However, we believe his discussion incorrectly cites the literature. 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. Admission NIHSS ranged from 8-27 and recanalization occurred between 7-49 min of carotid access. This technique was not associated with any new neurological deficits or radiographic ischemia. The Journal of Neurological Surgery (JNLS) publishes in two parts: JNLS Part A: Central European Neurosurgery JNLS Part B: Skull Base. Challenging anatomy for carotid artery access can result in a delay to achieve successful recanalization in patients with acute ischemic stroke. Since then, Congress has intervened on 13 separate occasions to prevent additional cuts from being imposed. Primary MAT is an alternative endovascular recanalization technique with reasonable first pass efficacy that will likely improve with technology and experience. 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. The catheter was wedged into the thrombus followed by manual aspiration with a 20 ml syringe. Delayed parent vessel occlusion occurred in two cases (8.3%), both grade C2 (p=0.014). Cases of reversible vasculopathy have also been reported in menopausal women. ;] 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. This technique may facilitate the use of new stent technologies for the treatment of aneurysms that would otherwise be untreatable with endovascular therapies. The Journal of Neuroradiology is a peer-reviewed journal, publishing worldwide clinical and basic research in the field of diagnostic and Interventional neuroradiology, translational and molecular neuroimaging, and artificial intelligence in neuroradiology.. Journal of neurointerventional surgery. Methods: Interventional Neuroradiology (INR) is a peer-reviewed clinical practice journal documenting the current state of interventional neuroradiology worldwide. The technical success rate was 98%. Interobserver agreement using simplified scales for occlusion (Montreal) and parent artery patency were higher for DSA (0.88 and 0.61) and CE-MRA (0.74 and 0.55) than for 3D-TOF-MRA (0.51 and 0.02). A single-center aneurysm database was reviewed to identify patients who underwent anterior circulation aneurysm embolization with the PED while using the Navien distal intracranial catheter. 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. Two of the four strokes occurred in vascular territories separate from the target carotid artery. The Navien catheter (5 Fr, 0.070 inch outer diameter, 0.058 inch inner diameter, 115 cm) was used in 78 cases of anterior circulation PED. The Journal of NeuroInterventional Surgery (JNIS) is a leading peer review journal for scientific research and literature pertaining to the field of neurointerventional surgery. Asymptomatic patients with moderate ISR (50-69%) at 6 months can be safely followed conservatively. 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. Previous studies have described a correlation between variants of the circle of Willis and pathological findings, such as cerebrovascular diseases. At 2 months followup, all patients had survived with mRS 0-4 except for one patient who had a large infarct despite 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. Bihemispheric PICA crosses midline and typically serves both PICA territories. Safe deployment through an occluded vessel may be assisted by use of an intermediate catheter. The Journal of NeuroInterventional Surgery™ (JNIS) is the leading peer-reviewed journal for scientific research and literature pertaining to the field of neurointerventional surgery. Conclusions: You can use it to subscribe to this data in your favourite RSS reader or to display this data on your own website or blog. In fact, I am not a regular reader of your journal. Methods: Thus it can pose significant therapeutic challenges. Implantation of the LVIS Jr device as a support device for stent-assisted coil embolization seems to be safe and effective. Results: Large unruptured AVMs (Spetzler-Martin grades IV-V) should be treated with target embolization of high flow fistulas or intranidal aneurysms. Vertebral artery origin anomalies are typically incidental findings during angiography or post mortem examination. Brain arteriovenous malformations (AVMs) are a rare pathology, and their treatment is discussed. The four patients reviewed were all treated using coils. The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. Her examination was remarkable only for a partial left third nerve palsy manifest as a non-pupil sparing mild ptosis. Larger studies with a longer follow-up are needed to further delineate the safety and efficacy of this technique. Aneurysm occlusion rates were similar in both groups. 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. 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). Extremely low groin morbidity is achievable using rigorous parameters around femoral catheterization in children. Compared with the Orbit/Galaxy coils, our analysis suggests that the Penumbra coil is more efficient and cost effective in the treatment of intracranial aneurysms. 16 aneurysms embolized with the PC 400 in 2011 were compared with 79 equally matched aneurysms embolized with conventional coils from 2004 to 2011. Results: 84 patients (52 men, 32 women; mean age 38.2 years; range, 9-70 years) were treated at our institution with Onyx18 from 2001 to 2011. Methods: 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. A reversible cerebral vasoconstriction syndrome may occur in some circumstances after a hysterectomy with bilateral salpingo-oophorectomy. Journal of NeuroInterventional Surgery Publication Information. This was accomplished in a median time of 20 min compared with 45 min in the Penumbra Pivotal trial (p<0.0001). 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. The branching point to the contralateral hemisphere always occurred distal to the ascending tonsillar loop and all true bihemispheric variants had contralateral PICA aplasia. Five ischemic strokes were secondary to vasospasm; one was definitely related to thrombus formation within the stent and one was possibly related to the stent. Latest articles in this journal Transition to virtual appointments for interventional neuroradiology due to the COVID-19 pandemic: a survey of satisfaction Ronda Lun, Gregory Walker, Zeinab Daham, Tim Ramsay, Eduardo Portela De Oliveira, Mohammed Kassab, Robert Fahed, Aiman Quateen, Howard Lesiuk, Marlise P Dos Santos, et al. The study included a total of 75 consecutive patients treated with stent-assisted coiling. 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. The routine use of seizure prophylaxis following aSAH is controversial. A third nerve palsy is most often associated with posterior communicating artery aneurysms which are explained by the anatomic proximity of nerve and artery. The final catheter tip position was in the cervical ICA (1/78, 1%), petrous ICA (23/78, 30%), proximal cavernous ICA (48/78, 62%), distal cavernous/clinoidal ICA (3/78, 4%), supraclinoid ICA (2/78, 2%) and the M1 segment (1/78, 2%). The results of the EC-IC bypass group trial in 1985 were surprising to many and sobering to all; EC-IC bypass for stenosis or occlusion of the high internal carotid artery or middle cerebral artery did not decrease the risk of subsequent stroke compared with medical management. We reviewed cases of acute ischemic stroke in which direct carotid artery puncture was used for access. Standard Journal Abbreviation (ISO4) - Journal of NeuroInterventional Surgery The Standard Abbreviation (ISO4) of Journal of NeuroInterventional Surgery is “J Neurointerv Surg” . I am not a neurosurgeon, neuroradiologist, nor interventionalist. The etiology of SAM remains indeterminate although there is evidence it may be an endogenous pathological response to vasospasm. Methods and results: It has been hypothesized that mass effect, hemotoxicity and ischemia are all possible causes of third nerve injury in remote aneurysms, as in this case. The 30 day stroke and death rate for symptomatic patients was 2.5% and for asymptomatic patients 1.4%. In each case the catheter was tracked to its desired position (100% clinical success) despite significant proximal vessel tortuosity in 34 cases (44%). The FRED system was technically easy to deploy with no procedural complications occurring in this first reported series of 14 aneurysms. Aneurysm size ranged from 2.5 to 24 mm and neck width from 2 to 8 mm. Stenting and angioplasty were then performed, followed by removal of the embolic protection device which had visibly trapped debris. For topics on particular articles, maintain the dialogue through the usual channels with your editor. 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. Treating either lesion first has its respective shortcomings. A single aneurysm was treated without coil embolization. More studies are required to further establish the pathophysiology, diagnosis and treatment of this condition. The authors have designed and implemented an Enhanced Recovery After Spine Surgery (ERASS) protocol for patients undergoing elective procedures at a tertiary care facility and evaluated the ERASS protocol's efficacy (e.g., opiate use on postoperative day 1 and length of stay) by comparing patients enrolled in the ERASS group (n = 97) to a historic cohort (n = 146). The Journal of NeuroInterventional Surgery (JNIS) is a Plan S compliant Transformative Journal. 46 talking about this. Data were collected prospectively from 296 consecutive elective CAS procedures. Three interventional neuroradiologists, two neurosurgeons, and two neurologists rated the image quality of all 3D reconstructions as good, acceptable, or poor. Only a single center employed EEG routinely in all aSAH patients but most supported EEG use when the neurologic examination was unreliable or inexplicably declining. Neuroradiologists, neurologists, and neurosurgeons should be aware of this potential variant. Results 61 complications occurred during coil embolization and 33 periprocedural complications occurred within 1 week. Journal of neurointerventional surgery (Online) (DLC) 2010233981 (OCoLC)471506510: Material Type: Periodical, Internet resource: Document Type: Journal / Magazine / Newspaper, Internet Resource: All Authors / Contributors: Society of Neurointerventional Surgery. At 1 month follow-up, the patient had no complaints and showed complete resolution of all oculomotor symptoms. Based on our observation that cerebral complications are associated with this treatment, we predict that the number of intraprocedural complications will rise as a result of this trend. PLUS: Download citation style files for your favorite reference manager. Data Source: Scopus®, Metrics based on Scopus® data as of April 2020. These complications were observed in 8.6% of ruptured aneurysm embolization procedures (55/637) and in 3.5% of unruptured aneurysm embolization procedures (39/1127). 51 patients were treated with the Wingspan stent system for a symptomatic intracranial atherosclerotic stenosis of 50-99%.
