O-015 The safety and efficacy of cangrelor use in endovascular thrombectomy compared with glycoprotein IIb/IIIa inhibitors
ConclusionCangrelor use was associated with a decreased risk of hemorrhagic conversion and may lead to favorable functional outcomes for patients during hospitalization when compared to GPI use. Future prospective studies are warranted to investigate its use in EVT.Disclosures A. Devarajan: None. S. Gottiparthi: None. J. Zhang: None. D. Goldman: None. A. Schupper: None. C. Rossitto: None. J.

O-018 Utilizing DSC MR perfusion images for evaluation of hemorrhagic transformation after mechanical thrombectomy with Heidelberg grading and comparison to SWI, GRE, and CT
ConclusionAmong the 3 acquisitions, HT was identified more often on SWI/GRE than on CT or MR perfusion. For HT more likely to be clinically significant (Heidelberg grade 2 or higher), both SWI/GRE and DSC-MR perfusion performed similarly to CT. Thus, when obtaining DSC MR perfusion images for ischemic stroke imaging, SWI/GRE may not be necessary for evaluating HT.Abstract O-018 Figure 1Disclosures C. Reynolds: None. B. Renshaw: None. S.

O-026 Incremental value of arterial spin labeling (ASL) over conventional MRI sequences in the detection of intracranial arteriovenous malformations in patients with hereditary hemorrhagic telangiectasia (HHT)
ConclusionsOur findings underscore the incremental value of ASL in addition to conventional MRI sequences as a screening tool in the detection of brain AVMs in patients with HHT. ASL was more sensitive than conventional contrast-enhanced MRI alone, potentially improving diagnostic accuracy in this patient population with many small AVMs. These findings further highlight the need for further research to explore the benefits of integrating ASL sequences into the initial evaluation and routine follow-up of patients with sporadic and HHT-related brain AVMs.Abstract O-026 Figure 1Disclosures W.

O-027 Contrast density and volume on post-thrombectomy dual-energy head computed tomography predict delayed hemorrhagic transformation
ConclusionMaximum contrast density predicted the occurrence of delayed petechial hemorrhage, while contrast volume predicted the occurrence and volume of delayed parenchymal hematoma. The volume of contrast on DEHCT can serve as a useful predictor of DHT and may have implications for patient management.Abstract O-027 Figure 1Disclosures S. Ahn: None. S. Roth: None. Y. Ko: None. A.

O-035 Endovascular treatment of cerebral venous thrombosis involving the deep venous system
ConclusionsAlthough deep venous involvement of CVT is uncommon, these patients are at risk of quickly becoming critically ill with an elevated rate of death or dependency. Although these patients may develop stroke, hemorrhage, or neurologic decline prompting consideration of endovascular therapy, the deep cerebral venous system is not easily accessible with catheters due to small lumens and risk of perforation. It has been proposed that deep cerebral veins may have a higher chance of recanalization if venous thrombus burden is reduced in other parts of the dural venous sinuses. Current literature has not fully explored th...

O-042 Complications of DAPT cessation at 3 months versus 6 months after flow diversion of unruptured intracranial aneurysms
ConclusionsOnly 0.6% (n=1) of patients exhibited complications after 3 month follow-up. We conclude that DAPT duration of 3 months after endoluminal flow diversion of unruptured cerebral aneurysms of the anterior circulation is not associated with increased rates of hemorrhagic or thromboembolic complications compared to a traditional 6-month regimen.Disclosures S.

O-065 Multicenter investigation into presentation, management and outcome of infectious intracranial aneurysms
ConclusionPatients with IIAs are at high risk of aneurysm rupture or re-hemorrhage despite treatment with antibiotics. Antibiotic failure occurred in 43% of medically treated patients, and failure was associated with 6 times higher odds of mortality in 1 year.Disclosures A. Alawieh: None. L. Dimisko: None. Y.

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...

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....

E-006 U.S. health care system-wide transition from alteplase to tenecteplase before mechanical thrombectomy: functional outcomes, early reperfusion rates, intracranial bleeding and femoral access site complications
ConclusionsThe first-year experience demonstrates the effectiveness and safety of the transitioning from TPA to TNK. The higher early recanalization rates with TNK are striking. Additional studies are required to investigate whether TNK is superior to TPA in the setting of LVO stroke.Disclosures M. Collins: None. C. Schirmer: None. G. Weiner: None. O. Goren: None. I.

E-007 CLEVER: clinical evaluation of WEB 0.017 device in intracranial aneurysms - final results for ruptured and unruptured aneurysm at 12 months
ConclusionThese results show good efficacy and safety results at 12 months month, and no WEB related mortality at 12 months. These data confirm the safety and efficacy of WEB 0.017 use in intracranial aneurysm treatment, unruptured as well as ruptured, and are consistent with the results published up to date.Disclosures L.

E-020 Flow diversion for intracranial aneurysms: intracranial hemorrhage and thromboembolic complications in a multi-center cohort of 200 patients
ConclusionComplication rates in our study are comparable to previous reports, and our findings further support the general safety and efficacy of flow diversion. Despite a relatively large population, the low number of ICH and TE complications limit statistical significance. Further study of complications in more robust samples are needed. However, the descriptive understanding of these complications can help direction future investigations.Abstract E-020 Table 1ICH and TE Stratifications ICH Non-ICH p n=7 n=193 Hypertension 7 (100%) 97 (50.3%) 0.035 Currently Smoking 3 (42.9%) 28 (14.5%) 0.319 Mean Procedural Fluoroscopi...
