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-142 A new graphical interface to capture quantitative venous outflow metrics
ConclusionsOur newly developed graphical interface allows users to output quantitative metrics that may represent AIF and VOF. These metrics should be checked against existing scales for association and performance.Abstract E-142 Figure 1Disclosures G. Adusumilli: None. S. Christensen: 2; C; iSchemaView. 4; C; iSchemaView.

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-151 Efficacy of an incidental aneurysm alert system (IAAS) and the associated disparities of incidentally detected intracranial aneurysms
ConclusionsIAAS is an effective alerting system and can improve the management of incidentally discovered cerebral aneurysms. The natural history of cerebral aneurysms may differ for Hispanic andAsian Americans, suggesting a potentially higher risk at presentation. Future research is needed to better understand these disparities’ causes and reduce their risks.Disclosures K. Fukuda: None. Y. Ghochani: None. D. Enzmann: None. C. Arnold: None. X. Chen: None. J.

E-152 Cone-beam CT angiogram acquisition in the angiography suite for LVO detection in acute ischemic stroke
ConclusionDTAS triage workflow with cone-beam head CT and CTA image acquisition in the angiography suite may be a next step to further optimize LVO stroke pathways by bypassing conventional CT/MR. This new workflow has the potential to further decrease door-to-needle times and thereby may improve patient outcome.Disclosures A. Kuhn: None. J. Singh: None. M. Garcia: None. S. Sarid: None. M.

E-164 Symptomatic developmental venous anomaly thrombosis associated with covid-19 infection
We describe a milder case of DVA thrombosis in the setting of COVID-19 infection presenting with unilateral hemiparesis requiring medical management alone. A 41-year-old female with hypertension who presented with left hemiparesis. Non-contrast computed tomography (CT) of head revealed linear calcifications in the right centrum semiovale consistent with DVA. Magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the right corona radiata adjacent to the vascular abnormality. Extensive workup for other causes of ischemic stroke was unrevealing. Cerebral angiography ruled out arteriovenous shunting and did not ...

E-189 Outcomes of tenecteplase versus alteplase after mechanical thrombectomy in a multiethnic stroke consortium registry
ConclusionIn this prospective, multi-center stroke consortium study, IV TNK in comparison to tPA prior to MT for ischemic stroke resulted in non-inferior outcomes related to angiographic reperfusion and functional status at discharge. These findings compliment the current literature and include a large Hispanic US cohort. Further analysis will include expansion of contributing centers and use of propensity scoring.Abstract E-189 Table 1 and 2Disclosures M. Gaub: None. D. Ramaswamy: None. A. Cardentey: None. S.

E-203 Dynamic extrinsic compression of extracranial cerebral arteries causing recurrent strokes

E-212 A comparison of outcomes between transfemoral versus transradial access for carotid stenting
ConclusionThe TR approach is safe, feasible, and provides similar rates of complications and high rates of successful stent deployment compared with the TF route. Neurointerventionalists adopting the radial first approach should carefully assess the pre-procedural computed tomography angiography to identify patients amenable to TR approach for carotid stenting.Abstract E-212 Table 2Comparison of outcomes between trans-radial vs trans-femoral access Outcome Trans-Femoral (n=232) Trans-Radial(n=110) Odds Ratioβ(95% CI) p-valueβ Odds Ratio*(95% CI) p-value* Primary Outcome: Any Complication, n (%) 15 (6.5%) 3 (2.7%...

E-226 Endovascular treatment of pediatric arteriovenous shunts
ConclusionEndovascular treatment of pediatric arteriovenous shunts is extremely difficult and associated with high risks of complications. However, excellent clinical results can be achieved in specialized clinics. The choice of embolic agent should depend on the hemodynamic load of the pathological blood flow.Disclosures V.

E-231 Long-term safety and efficacy of the pipeline embolization device for treatment of small vs. large aneurysms: a systematic review and meta-analysis
ConclusionThe long-term occlusion rate after PED treatment is higher in large vs. small aneurysms. Symptomatic thromboembolic rates with stroke are also higher in large vs. small aneurysms. The difference in the rates of aneurysm rupture and intracranial hemorrhage was insignificant. Although the PED seems a safe and effective treatment for small and large aneurysms, further studies are required to clarify how occlusion rate and morbidity are affected by aneurysm size.Disclosures A.

E-257 Flow diversion of the ophthalmic aneurysms, outcomes in relation to the ophthalmic artery origin
ConclusionFlow diversion is safe and effective for carotid ophthalmic aneurysms treatment. Adjunct coil embolization and ophthalmic artery origin in relation to the aneurysm sac are independent factors that can influence treatment result, and should be considered when planning treatment.Disclosures M.

E-260 Bilateral cerebral arteriovenous shunting through pial and perforating vessels with multiple strokes and intraparenchymal hemorrhages in a patient with hepatopulmonary syndrome
This study presents a unique case of a 54-year-old male patient with a history of stroke, liver cirrhosis, portal vein thrombosis, hypertension, diabetes, and bladder cancer, who experienced multiple episodes of intracranial hemorrhages, stroke and worsening confusion over the past five years. The patient‘s clinical presentation raised suspicion for an underlying occult vasculopathy. Digital subtraction angiography (DSA) revealed multiple curvilinear, irregular, bilateral pial vessels with early high-flow arteriovenous shunting, consistent with vascular shunting that is associated with liver cirrhosis. The patient&ls...

Slow is smooth, smooth is fast
Modern infantry combat motto. If you can’t move, you get pinned down but if you move too fast you get outflanked and surrounded. The milestone trials1 in 2015 showed that patients with large vessel occlusion can be effectively treated to prevent future disability and, to a certain extent, their mortality. Large vessel occlusion thrombectomy opened the doors of a new era in neurointerventional surgery, in which small departments, often handled by one or two operators, had to pivot and face a steady, continuous increase in the number of procedures two- or threefold their usual capacity. Stroke can also be held accounta...
