P62 Continuing early mTICI 2b reperfusion during mechanical thrombectomy is not beneficial for all patients
ConclusionContinuing MT after early mTICI2b might improve functional outcome of the patients who are successfully converted to mTICI2c/3 but an increase in complications due to further retrieval attempts may diminish the potential functional benefit.ReferencesGoyal M, Menon BK, Van Zwam WH, et al.

P-028 Impact of the covid-19 pandemic on the intracranial aneurysm treatment and associated outcomes: a propensity score matching study
Conclusions and RelevanceThe COVID-19 pandemic has significantly impacted the healthcare system and has led to changes in the treatment of various neurological conditions, including ICAs. The pandemic resulted in a shift in the treatment of SAH and an increase in endovascular procedures over open surgical clipping. COVID-19 infection has been associated with an increased risk of ischemic stroke and worsened outcomes for stroke patients. Further research is necessary to understand the long-term effects of the pandemic on the healthcare system and patient outcomes.Disclosures A. Ghaith: None. M. Ghanem: None. E. Greco: None....

P-026 pufs primary endpoint complications by aneurysm size
ConclusionsAll 6 major neurologic morbidity and neurologic mortality events in the PUFS trial was observed in 84 patients harboring large aneurysms, for 7% complication rate in this subgroup. Patients with giant aneurysms suffered no such complications, however, their parent vessel occlusion rates were higher at 18.2% (4/22). More aggressive or more prolonged antiplatelet treatment may be necessary in patients with giant aneurysms treated with flow diversion alone.DisclosuresT. Becske: 2; C; Proctor for Covidien. M.

P-001 Permanent Implantation of the Solitaire Device as a Bailout Technique for Large Vessel Intracranial Occlusions
ConclusionWith the recent over-whelming evidence demonstrating the effectiveness endovascular therapy in acute ischemic stroke, the expansion of stroke therapy requires that a variety of techniques be available to the operators. Permanent implantation of the Solitaire stent achieves adequate distal flow and good clinical outcomes in the setting of AIS. This case series suggests this technique provides a safe alternative for difficult cases refractory to other revascularization techniques.Key Wordsstroke, revascularization, stentDisclosuresJ.

O-032 Treatment outcomes for ARUBA eligible brain arteriovenous malformations: a comparison of real world data from the NVQI-QOD AVM registry to the ARUBA trial
ConclusionARUBA eligible patients from the NVQI-QOD registry demonstrate a significantly lower risk of stroke or death with intervention of 8.0% (N=174) compared to the 30.7% (N=114) ARUBA trial interventional risk, and is nearly equivalent to the ARUBA trial medical management risk of 10.1% (N=109) over 33 months.Disclosures N.

P-011 Risk of intracranial hemorrhage associated with rescue intracranial stenting in patients who receive IV thrombolysis
ConclusionsIn this retrospective study of a 10-year experience at a high-volume comprehensive stroke center, our study shows that rescue stenting after failed mechanical thrombectomy in the setting of prior administration of IV thrombolysis appears to be associated with a higher rate of all types of intracranial hemorrhages, but similar rates of symptomatic intracranial hemorrhage. 90-day functional status was better in the patients who received IV tPA, although the 90-day mortality was higher. Our report suggests that further larger studies are needed to determine the safety and efficacy of RS for failed mechanical thromb...

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 ...

Efficacy of intra-arterial therapy in the elderly requires further study
We salute Dr Ghobrial and colleagues for their important contribution regarding the endovascular management of elderly ischemic stroke patients.1 Although this topic is relatively new to the literature, it is of critical importance to the field of intra-arterial therapy (IAT), given the increasing use of catheter based stroke therapies2 and the expanding population of elderly Americans who are at the highest risk for ischemic stroke. The authors conducted an extensive, retrospective, single center study using chart review that identified elderly patients (aged >75 years) that underwent IAT between 2006 and 2012. Th...

O-025 The Superiority of Thrombectomy over IV rtPA Monotherapy May be Associated with Thrombus Length - Results of the THERAPY Trial
ConclusionExtensive thrombus burden presents a challenge for stroke intervention, posing greater risk of complications and poor clinical outcome. However, this effect is dampened when IAT is the interventional modality, leading to a more favorable prognosis over IV-rtPA alone. This study finding supports the use of aspiration thrombectomy in treatment of extended thrombi, demonstrating relative advantages over thrombolytic monotherapy, and enables better clinical outcomes.DisclosuresR. von Kummer: 2; C; Penumbra, Inc.
