O-034 Women with large vessel occlusion acute ischemic stroke are less likely to be routed to comprehensive stroke centers
ConclusionsLVO patients who presented to PSCs were less likely to receive EVT than patients directly presenting to a CSC. Anterior circulation LVOs were more likely to be transferred for EVT evaluation. Despite a higher NIHSS, and similar other baseline characteristics, female patients were less likely to be routed to a CSC.Disclosures M. Tariq: None. S. Salazar-Marioni: None. S. Khose: None. L.

E-057 Process Improvement in Door-to-Groin Puncture Times at a Comprehensive Stroke Center Shows a Trend Towards Reduced Mortality at 90 Days
ConclusionOur systematic process improvement initiative significantly reduced door-to-groin puncture times and showed a trend towards reduced mortality at 90 days. A multidisciplinary approach and ensuring hospital system investment are key to an effective process.DisclosuresY. Kayan: 2; C; Medtronic, Penumbra. J. Delgado Almandoz: 2; C; Medtronic, Penumbra. M.

P-006 evaluation of baseline ct aspects and admission neutrophil-lymphocyte ratio in perfusion-guided selected ica/mca stroke patients for endovascular reperfusion therapy
ConclusionsIn our cohort, baseline CT ASPECTS inversely correlated with admission NLR in anterior circulation AIS patients who had favorable perfusion imaging profile for IA reperfusion therapy. Additionally, in this subgroup of patients, NLR of 5 or less discriminated favorable from unfavorable ASPECTS.DisclosuresA. Honarmand: None. A. Shaibani: None. F. Syed: None. A. Elmokadem: None. M.

P-008 Normoglycemia following thrombectomy is associated with improved 90-day favorable outcomes in ischemic stroke patients
Conclusions Normoglycemia is an important marker following thrombectomy. If patients have normoglycemia following thrombectomy and recanculization, they are likely to have a favorable long-term course. Hyperglycemia following thrombectomy however is an indication of poor future outcome. Further studies are warranted to elucidate the validity of normoglycemia as a marker for long-term favorable outcome following thrombectomy. Disclosures B. Lucke-Wold: None. S. Boo: None. J.

Correlation of von Willebrand factor and platelets with acute ischemic stroke etiology and revascularization outcome: an immunohistochemical study

E-042 Clinical and cost effectiveness of using evolving ace reperfusion catheters as first-line treatment of acute ischemic stroke due to large vessel occlusions
Conclusion ADAPT with the ACE68 reperfusion catheter resulted in a significantly higher rate of successful reperfusion using aspiration alone (90%) compared to previous generation ACE catheters. ADAPT also resulted in significant cost savings compared to Solumbra or SR first-line approaches. Disclosures Y. Kayan: 2; C; Medtronic Neurovascular, Penumbra. J.

O-007 Recanalization and Outcome Comparisons in Acute Ischemic Stroke Patients Treated with Mechanical Thrombectomy Selected by CT/MR Perfusion Imaging Versus CT Angiography
ConclusionsMechanical thrombectomy patients selected by CTA or perfusion imaging demonstrated no difference in successful recanalization rate, but higher level of recanalization/reperfusion and a trend of improved outcomes with CTA selection that may be attributed to improved treatment times.DisclosuresA.

E-045 Product Cost and Utilization in Mechanical Thrombectomy: A Comparison of Techniques
ConclusionA cursory evaluation of the data from this selected subset of patients suggests that there may be no significant difference in overall product cost to the patient for utilization of these two techniques for performance of mechanical thrombectomy. However, upon closer inspection of the data, the cost for aspiration thrombectomy appears to vary quite widely across the subset, with a standard deviation of $22470.99, while the standard deviation for stent retrieval is $2846.91. It is difficult to determine whether this trend would be borne out in a larger sample set; however, it may suggest that product utilization i...

E-069 Fluoroscopy Time and Radiation Dose in Mechanical Thrombectomy: A Comparison of Techniques
ConclusionData from this limited subset of patients suggest a statistically significant difference in fluoroscopy time for mechanical thrombectomies performed with stent retrieval versus those performed with suction aspiration. No significant difference was seen in dose area product data.The difference in fluoroscopy time between the two techniques may reflect operator comfort rather than intrinsic differences between the two techniques. Notably, however, these data were obtained across multiple operators at our institution, so it may be plausible that these differences are generalizable to technique. It is important to ag...

E-070 The use of inpatient virtual shared medical appointments for patients with acute cerebrovascular pathologies and their caregivers: a pilot study to improve health literacy, patient self-efficacy and reduce provider burnout
ConclusionsImplementation of a vSMA program at a tertiary care center during a pandemic was feasible. Themes caregivers expressed on the post-survey included better understanding of caring for a stroke patient, and coping with the unpredictability of a patient’s prognosis. The pandemic has precipitated shifts towards telehealth, but our study highlights the importance of avoiding marginalization of the elderly and less technologically inclined populations.Tables to be presented:Abstract E-070 Table 1Inclusion and exclusion criteriaAbstract E-070 Table 2Characteristics of Study ParticipantsAbstract E-070 Table 3Patien...

P-014 Improvement in Angiographic Transit Times Post Endovascular Vasospasm Treatment in Patients with Aneurysmal Subarachnoid Haemorrhage
Conclusion The DSA TT correlated with improvements in neurological status in patients with clinical vasospasm. TT might reflect a better way to assess vasospasm severity and response to treatment as compared to vessel diameter. This method may serve as a useful indirect technique for cerebral blood flow assessment in the angiography suite.

Cerebral vasospasm patterns following aneurysmal subarachnoid hemorrhage: an angiographic study comparing coils with clips
Conclusions Patients with aSAH treated by endovascular coiling and surgical clipping demonstrate distinct vasospasm patterns. While both initially exhibit perianeurysmal spasm, patients treated by coiling go on to develop stepwise progression distally over time. This finding may reflect dispersion of blood breakdown products along preserved CSF egress pathways in patients treated by endovascular coiling.

Assessment of intracranial aneurysm rupture based on morphology parameters and anatomical locations
Conclusions Size ratio, height–width ratio, aneurysm inclination angle, aneurysm shape, and aneurysm location might be important for discriminating between ruptured and unruptured aneurysms. Further investigation will determine whether these morphological parameters and anatomical locations will be reliable predictors of aneurysm rupture.
