E-078 Advancement in coil technology for treatment of brain aneurysms
ConclusionThis study concludes that is SMART coil system is safe and efficacious for the use in Endovascular treatment of intracranial aneurysms. The smart coil system is promising in the treatment of wide spectrum of intracranial aneurysms. The result of follow up angiographic data should reflect the high packing density and will be published when completed.Disclosures S. Khairandish: None. S. Pakbaz: None. M. McManus: None. G.

E-089 Rural versus metropolitan stroke activation incidence: using Viz.ai to determine disease penetrance
ConclusionCompared to a metropolitan PSC in our network, two rural PSCs had significantly higher per capita incidence of stroke activations. There was a trend toward higher per capita thrombectomy alerts as well. Given the known health disparities in rural regions of the US, these findings provide clear confirmation of the importance of stroke care protocols in rural areas, and the value of rapid identification and triage for rural communities. Our future studies will examine more detailed patient-specific factors based on geographic region.Disclosures J. Fraser: None. J. Frank: None. A. Chen: None. M. Campbell: None. L. W...

E-098 Initial experience with the pipeline vantage flow diverter - vantage one study: six-month results, technical and clinical consideration
ConclusionThe new PVED reveals improved device visibility, ease of delivery and repositioning with precise distal opening in comparison to previous PED generations. Initial results demonstrate overall good device performance, safety profile and effectiveness. The implant requires a modified deployment technique for successful vessel wall apposition of the proximal stent as opposed to the previous generations of PED.ReferencesLylyk I, Scrivano E, Lundquist J, Ferrario A, Bleise C, Perez N, Lylyk PN, Viso R, Nella-Castro R, Lylyk P.

E-107 Carotid artery stenting in patients with symptomatic non-stenotic carotid artery disease - a case series
ConclusionsIn this case series performed over a 10-year period at a high-volume stroke center we show that CAS is safe and efficient in patients with SyNC. Previous studies have established safety and effectiveness of CES in patients presenting with SyNC, however there is a paucity of reports in the literature regarding the effect of CAS in this patient population. Recent guidelines have brought specific attention to high-risk plaque characteristics which suggest that plaque instability plays a major role in the onset of ischemic events, regardless of lumen narrowing. Advanced imaging techniques, such as Optical Coherence ...

E-110 Bilateral hypoplasia of the internal carotid artery (ICA) and intracranial vasculopathy with 'moyamoya phenomenon in association with alagille syndrome
ConclusionThe educational value of our case lies not only in the rarity of the condition but also in the uniqueness of patient presentation. It would be a helpful addition to the existing literature on rare genetic syndromes with cerebral vasculature involvement.Abstract E-110 Figure 1Disclosures H. Shakeel: None. J. Gandhi: None. R.

E-115 Trans-radial versus trans-femoral access routes for diagnostic cerebral angiograms: a large single-center comparative cost-analysis study
ConclusionOverall, our study shows that the TR approach can be less a less expensive option for patients undergoing diagnostic cerebral angiograms, especially if complications occur. Future studies can corroborate our findings and potentially lead to the adoption of TR as a low-cost, efficient, gold-standard technique for cerebral angiography.Costs (dollars) Associated with Trans-Radial Versus Trans-Femoral AccessAbstract E-115 Table 1 Variable Trans-Femoral (n=314) Trans-Radial(n=612) P-value Total Cost, mean (SD) 12591.8 (19128) 12789.5 (18424) .88 Catheters, median (range) 12.4 (12.4-1900) 55.2 (12.4-369) .03 Closure d...

E-126 Multicenter flow diversion in 200 patients for treatment of intracranial aneurysms
ConclusionThis report characterizes patient demographics, aneurysm characteristics, procedure complications and long-term angiographic and clinical outcomes for a large patient population across multiple medical centers treated with flow diversion. Overall, procedures resulted in a high rate of occlusion and low rate of serious complications. Continued iterative outcomes analysis is warranted particularly as flow diversion technology evolves. Despite diverse hospital settings, differences in presentation, patient characteristics and the inclusion of off-label treatments, flow diversion procedures remained safe and effectiv...

E-135 Dejerine-roussy syndrome in the setting of right sigmoid sinus thrombosis: a unique case report
DiscussionThis case illustrates the important clinical aspects and physical findings needed to diagnose DRS. The presence of focal allodynia and hyperalgesia with recent cerebrovascular incidents provides significant evidence for DRS. The purpose of this case is to provide awareness and to increase clinical suspicion of DRS during examination, especially in the setting of cerebral venous sinus occlusion as infarction alone may not present as atypical allodynia.Disclosures S.

E-150 Mechanical thrombectomy in distal middle cerebral artery occlusions using a novel blind exchange mini-pinning technique: experience in 7 consecutive cases
ConclusionBlind mini-pinning allows for combined use of distal stentriever with a 035 thrombectomy catheter, affording a larger ID than traditional microcatheter engagement of the thrombus with enhanced stability for removal, and improved reperfusion rates in distal occlusions. This technique may be efficacious for the treatment of distal occlusions and further studies are needed to compare outcomes in distal occlusions.Abstract E-150 Figure 1(A) Deployment and blind mini-pinning navigation of 035 aspiration catheter (blue) through 071 (black) and 088 thrombectomy catheter (orange) into the M2 segment with follow-up angiog...

E-006 U.S. health care system-wide transition from alteplase to tenecteplase before mechanical thrombectomy: functional outcomes, early reperfusion rates, intracranial bleeding and femoral access site complications
ConclusionsThe first-year experience demonstrates the effectiveness and safety of the transitioning from TPA to TNK. The higher early recanalization rates with TNK are striking. Additional studies are required to investigate whether TNK is superior to TPA in the setting of LVO stroke.Disclosures M. Collins: None. C. Schirmer: None. G. Weiner: None. O. Goren: None. I.

E-012 Reasons for choosing nondominant vertebral artery as an access route in hyperacute vertebrobasilar ischemic stroke
ConclusionsUndoubtedly, the fastest treatment is best through the dominant VA. Nondominant VA may be another option in situations where it is accessible, stable, or less risky despite nonvisualized VA in angiogram.Disclosures G. Lee: None. C. Yang: None. C. Kang: None. J.

E-044 Long-term safety and efficacy of pipeline embolization device compared in anterior and posterior circulation aneurysms: a systematic review and meta-analysis
ConclusionThe long-term occlusion rate after PED was higher in AC aneurysms and the cumulative incidence of ischemic complications and aneurysm rupture was significantly higher in PC. The intracranial hemorrhage rate was not different. More extensive studies are required to identify factors predisposing to incomplete occlusion and postprocedural complications.Disclosures E.
