Regarding the 29 patients presenting with diplopia, one could debate whether treatment is necessary or even helpful; the authors cite articles on the subject but fail to mention that in …. We treated four patients in whom we redirected the pre-existing flow in the supraclinoid ICA into the ipsilateral A1 and M1 segments, to a new unilateral, linear flow from the supraclinoid ICA solely into the ipsilateral M1 segment. The Journal of the Society of NeuroInterventional Surgery. Conclusions: The perioperative CAS complications in this series were well below the 6% for symptomatic patients and 3% for asymptomatic patients currently recommended based on historic carotid endarterectomy data. MRI of the cervical spine demonstrated a gadolinium enhancing mass arising from the dorsal cervical dura, extending from the occiput to C2, with internal flow voids and extension into the C2 lamina and spinous process. Seven patients (58.3%) in the first group and none in the second had FER(24) on interval imaging after intervention (p=0.04). Vertebral artery origin anomalies are typically incidental findings during angiography or post mortem examination. The branching point to the contralateral hemisphere always occurred distal to the ascending tonsillar loop and all true bihemispheric variants had contralateral PICA aplasia. The Navien, either 6 F 0.072 inch ID or 5 F 0.058 inch ID, provided ultra-distal large-bore access in the following 11 intracranial interventions: anterior circulation aneurysm treatment with Pipeline embolization device (PED) (n=3); posterior circulation aneurysm single-stage stent coiling (n=5); liquid embolization of arteriovenous malformations (n=2); PED coiling of posterior circulation aneurysm (n=1). This manuscript describes certain important aspects of the 2012 physician fee schedule. We describe the technical aspects, limits, and potential complications associated with direct carotid artery puncture for intracranial acute ischemic stroke interventions, and present cases to illustrate the utility of this access approach. We devised a simple grading scheme based on the pattern of parent artery and aneurysm neck reconstruction, and correlated it with long term outcome. Aneurysm occlusion was assessed with full and simplified Montreal scales and parent artery patency with three-grade and two-grade scales.

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. Purpose: Digital subtraction angiography demonstrated multiple corkscrew-shaped supplying vessels, marked hypervascularity, rapid arteriovenous shunting and delayed contrast washout. International Collaboration accounts for the articles that have been produced by researchers from several countries. Abbreviation: J Neurointerv Surg. The therapeutic strategy should be to cure small and medium AVMs with endovascular treatment alone or combined treatment. Extremely low groin morbidity is achievable using rigorous parameters around femoral catheterization in children. 12 patients had good initial proximal recanalization but a residual partial or total occlusion of the MCA while five patients failed any recanalization. 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. Standard Journal Abbreviation (ISO4) - Journal of NeuroInterventional Surgery The Standard Abbreviation (ISO4) of Journal of NeuroInterventional Surgery is “J Neurointerv Surg” . 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. Results: The purpose of this study was to determine if there were geographic and racial disparities in access to treatment of unruptured cerebral aneurysms based on the NIS. Demographic data, aneurysm characteristics and angiographic parameters were correlated with properties of DWI lesions. The focus of this study was to determine ease of deployment, safety and effectiveness of the LVIS Jr device. The 5 s 0.24 μGy/f protocol generates one-third smaller radiation dose than the standard 5 s 0.36 μGy/f protocol without compromising diagnostic image quality or accuracy. The two stent associated ischemic strokes and one symptomatic intracranial hemorrhage occurred in patients with Hunt and Hess grades III-V (n=17) and patients with external ventricular drains (EVDs) (n=17). The complete, comprehensive guide shows you how easy citing any source can be. 112 consecutive patients were evaluated. Distal parent vessel access was obtained by allowing the microwire to follow the local hemodynamics into a giant internal carotid artery aneurysm and around its dome. Methods Angiograms and clinical information derived from consecutive patients receiving treatment initiated within 6 h of stroke onset were retrospectively reviewed. Endovascular therapy is frequently the method of treatment in such situations but there remains a chance of incomplete recanalization. The Journal of NeuroInterventional Surgery (JNIS) is a leading peer review journal for scientific research and literature pertaining to the field of neurointerventional surgery. Citation analysis is a method of quantifying various metrics related to scholarly publications. 116 patients were reviewed from 2008 to 2011. 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. Results 61 complications occurred during coil embolization and 33 periprocedural complications occurred within 1 week. Despite this significant setback, cerebral revascularization is not obsolete. Acute, simultaneous, concomitant internal carotid artery (ICA) and middle cerebral arteries (MCA) occlusions almost invariably lead to significant neurological disability if left untreated. The overall 30 day stroke/death/MI rate was 5/226 (2.2%). Journal of NeuroInterventional Surgery (JNIS) [English] ISSNs.

Understanding the frequency and timing of ISR would be useful in developing optimal protocols for carotid stent surveillance. 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. A novel technique is reported that helps the operator in achieving reliable access to the distal parent vessel with a microcatheter for stent assisted aneurysm coiling. Aneurysm size ranged from 2.5 to 24 mm and neck width from 2 to 8 mm. Physical examination, imaging and laboratory findings were descriptive of RCVS, and the patient's rapid recovery was consistent with the usual disease progression of a reversible vasculopathy. 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. 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). The purpose of the SPEED study was to report the safety and effectiveness of the Penumbra 054 Reperfusion Catheter System in revascularizing large vessel occlusions. Immediate post-treatment angiography demonstrated reduced flow into all aneurysms although no long term angiographic data are yet available. 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).
