E-173 Thrombectomy passes and clinical outcomes in patients with stroke intervention beyond 24 hours
ConclusionIn our patients undergoing MT beyond the 24-hour window, the number of device passes was not associated with functional outcome, successful recanalization, or sICH. This may be due to the delayed intervention window, small sample size, or other factors. A larger study and further investigation is warranted.Disclosures A. Pandhi: None. A. Alrohimi: None. M.

E-177 Treatment of ischemic stroke in patients diagnosed with covid-19: a matched analysis of the national inpatient sample
ConclusionsIn this matched NIS analysis of patients treated for ischemic stroke with a concomitant COVID diagnosis, we demonstrate that EVT trends towards, although nonsignificant, higher rates of favorable functional outcomes when compared to medically managed patients.Abstract E-177 Table 1Patients with COVID and Acute Ischemic Stroke Comparing medical management vs EVT 1:1 Nearest Neighbor Matching for EVT based on Age, NIHSS, Gender, and Comorbidities Medically Managed N = 495 1 Endovascular ThrombectomyN = 495 1 p-value 2 Age in years at admission 66.82 ± 16.98 (19.00-90.00), (1.77) 65.67 ± 14.81 (28...

E-186 Assessing congruency of first pass effect on outcomes in mechanical thrombectomy for large vessel occlusions via unsupervised machine learning
This study was approved by the local institutional review board (IRB). Clustered outcomes to formulate clusters included the number of passes, the final reperfusion obtained, the discharge NIHSS, and complications. FPE was defined as TICI 2C or 3 reperfusions on the first pass. Uniform manifold approximations and projections (UMAP) and K-means unsupervised clustering were done to identify outcome clusters. Logistic regression with and without interaction coefficients was used to determine associated factors with cluster membership or FPE. P-values less than 0.05 were considered significant.Results287 consecutive patients w...

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-194 One road to two places: a unique case report of bilateral thalamic infarctions with neuroanatomical anomaly
ConclusionThe scientific relevance of the present case is to address various etiologies of bilateral thalamic stroke with special attention to single artery causes of bilateral strokes versus other causes of bilateral thalamic strokes. It is important to consider bilateral ischemic pathology, even as might arise from a single artery, as a differential in cases of acute encephalopathy. Reviewing the various etiologies of cerebral infarction can improve patient outcomes and provide a comprehensive understanding of the patients’ presenting symptomatology.A practice gap exists in the identification and treatment of bilat...

E-197 Use of balloon-mounted stents and drug eluting stents in intracranial atherosclerotic disease: single center experience
ConclusionDES appears effective and relatively safe with good long-term outcomes in treating intracranial atherosclerosis and secondary stroke prevention and is associated with lower delayed in-stent stenosis on follow up imaging compared to BMS and Wingspan stents. Use of DES for symptomatic ICAD in acute and non-emergent settings warrants further investigation.Balloon mounted stent, drug eluting stent, Wingspan, intracranial atherosclerotic disease, outcomes.Disclosures N.

E-207 Endovascular thrombectomy versus medical management for large vessel occlusion stroke patients with severe baseline disability: long-term outcomes and transitions to comfort care
ConclusionsAmong patients with severe baseline disability, EVT is associated with less post-stroke accumulated disability without limiting transitions to comfort care. EVT is compatible with goal-concordant care in patients with severe baseline disability; it should not be routinely withheld on the sole basis of baseline disability.Disclosures A. Awad: None. M.

E-211 Association of cerebrovascular injury and secondary vascular insult with poor outcomes following gunshot wound to the head in a large civilian population
ConclusionThese data suggest that intracranial CVI from GSWH and associated secondary vascular insult are associated with poor outcomes. Given the high prevalence and potentially reversible nature of these secondary injuries, early screening with vascular imaging and treatment of underlying cerebrovascular injury may prove critical to improve outcomes by reducing the rate of stroke and re-hemorrhage.Abstract E-211 Figure 1Disclosures J.

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-223 Improved time to diagnosis with portable MR imaging
ConclusionPortable MRI is a promising innovation with the aim to expand patient access and improve diagnostic times so that critical and potential lifesaving imaging diagnoses can be promptly treated with the urgency that is required. While initial analysis provides evidence that portable MRI has advantages over conventional MRI systems including workflow efficiency and improved patient imaging times, this will need to be compared to the unfortunate negative drawbacks of lessened image resolution and limited imaging sequences that come with the convenience of portable MRI systems. If the hypothesis is further corroborated,...
