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-088 A novel neuroprotection device, EnCompass F2 for improved stroke prevention in transcatheter aortic valve replacement: an in vitro study
ConclusionsIn our in vitro model, the EnCompass F2 filter stent demonstrated superior efficacy in providing full cerebral protection with smaller pores compared to the partial protection offered by the Sentinel device, potentially contributing to improved cerebral protection.Abstract E-088 Figure 1Disclosures M.

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-093 Carotid webs and stroke: a comprehensive overview of clinical characteristics, risk factors, and treatment modalities
ConclusionThis is the largest systematic review of CWs to date. This study provides novel information not only about risk factors and common treatment modalities for CWs, but also the relationship between CWs and stroke. This data may aid physicians in diagnosis of CWs in younger patients who present with stroke-like symptoms and no cardiovascular risk factors. Furthermore, medical treatment alone may not be as effective as stenting or surgical options.Disclosures N. Gupta: None. V. Kasulla: None. A. Shahbandi: None. J. Gendreau: None. R. Singh: None. N.

E-049 Complications of middle meningeal artery embolization - a systematic review
ConclusionThe published literature suggests that MMA embolization is a generally well-tolerated procedure, but with a low risk of significant complications, including, but not limited to stroke, seizures, visual obscurations, and facial palsy. Further studies and sub-analyses are needed to fully characterize the incidence of such complications.Disclosures J. Gerstl: None. M. Shafi: None. S. Badikol: None. N. Nawabi: None. R. Mekary: None.

E-051 Regional differences in infarction among stroke patients with low aspects: a retrospective cohort study
ConclusionBrain regions are differentially affected in patients with low ASPECTS, but whether this variability contributes to long-term outcomes and should guide treatment decisions requires further investigation with a larger sample size.Abstract E-051 Figure 1Disclosures M.

E-059 Endovascular thrombectomy after acute ischemic stroke of the basilar artery: a meta-analysis of four randomized controlled trials
ConclusionsEVT conferred significant patient benefit over MEDT alone in the treatment of PC-LVO. Future studies should better define patients in whom EVT is futile and determine factors that contribute to higher rates of sICH.Disclosures G. Adusumilli: None. H. Kobeissi: None. S. Ghozy: None. N.

E-061 Glycoprotein inhibitors as a standalone post-thrombectomy rescue treatment for intracranial atherosclerotic disease-related stroke: a systematic review and meta-analysis
ConclusionThese findings highlight the potential value of GPIs as a viable first line therapy for EVT rescue therapy in the setting of ICAD. This study was limited by the nature of the literature, which were non-randomized observational studies. Randomized controlled trials are needed to validate and refine our understanding of the role of GPIs in the management of refractory or re-occlusive ICAD stroke.Disclosures A. Brake: None. C.

E-070 Evaluation of flow control relative to guide catheter position during acute ischemic stroke treatment
ConclusionThe benchtop flow model provided physiologically-relevant vessel tortuosity, hemodynamics, and vessel material characteristics. The resulting quantification of the intracranial flow effects in the vessel branches during aspiration catheter placement provides valuable information regarding flow through the CW in the left-sided vasculature for comparison to placement in the right-side of the brain.Abstract E-070 Figure 1A: Test article Zoom 71 (Z71) and Zoom 88 (Z88) in the L-MCA.

E-071 Mechanical thrombectomy for isolated posterior cerebral artery occlusion stroke: systematic review and meta-analysis
ConclusionOur results suggest that MT for isolated PCA occlusion stroke is feasible. However, when compared with best medical management there is no difference in functional independence, 90-days mortality or symptomatic ICH. Given the limitations of our results, further confirmation in well-designed RCTs is needed.Abstract E-071 Figure 1Disclosures J. Sequeiros: None. M. Padilla: None. F. Terry: None. M.
