E-111 Repeat thrombectomy after large vessel occlusion stroke: incidence, clinical and technical outcomes
ConclusionsRepeat EVT for patients with re-occlusion within 30 days of thrombectomy is associated with favorable improvement in NIHSS, similar functional outcomes to patients undergoing single EVT, but has significantly higher risk of hemorrhagic conversion.Disclosures Y.

Real-world outcomes associated with the use of the EmboTrap revascularization device for ischemic stroke in the United States
Conclusions This is the first study in the US to report real-world outcomes sourced by retrospective database analysis among patients with AIS undergoing MT using the EmboTrap device. Further research is needed to better understand performance of the EmboTrap device in real-world settings.

E-060 Analysis of reported adverse events of flow-diverter stents for intracranial aneurysms using the FDA MAUDE database
ConclusionsPost-market surveillance is an important to guide patient counselling and identify adverse events and device problems that were not identified in initial trials. Although there are inherent limitations to the MAUDE database, our results highlight some important PR and DR complications that can help optimize patient counseling and management.Disclosures M.

E-096 COVID status is related to clot burden during thrombectomy in acute stroke patients
ConclusionOf 230 patients included in this interim analysis across 24 centers in the United States, between 02/2021 and 01/2022, 16 patients had a history of COVID. Comparing COVID-positive to non-positive, patients with COVID were younger (median 66.5 years vs 71.5 years, p 0.042), and had more intracranial clot by weight (median 101.0 mg vs 42.0 mg, p 0.047). There was a trend toward COVID positive patients to have more clot volume (median 180 cc vs 77.5 cc p 0.08), suggesting the difference was a higher clot burden instead of more density to the thrombus. These results suggest different histopathological characteristics...

E-182 A multicentric experience for the use of flow diverter in the treatment of anterior communicating artery aneurysms
ConclusionFlow diverters appear to be a safe and effective treatment for anterior communicating artery aneurysms, presenting as an alternative strategy in the armamentarium of interventionalist. Mid-term results were favorable, and complication rates were low. Additional studies with longer follow-up time and independent adjudication are warranted to confirm the safety and effectiveness of the technique.Disclosures V. Benalia: None. G. Cortez: None. N.

O-052 The pennsylvania post-market multicenter experience with flow re-direction endoluminal device (FRED)
ConclusionThe results of the early post-market experience with the FRED device show reasonable safety and adequate aneurysmal occlusion rates comparable to other flow diverters. However, more extensive multicenter studies with more extended follow-up data are needed to assess the long-term safety and durability of the device.Abstract O-052 Table 1Baseline descriptive statistics Number of patients n=61 Gender Male 11 (18%) Female 50 (82%) Age (Years: median; IQR) 58 (51 – 68) Multiple Intracranial Aneurysms 21 (34.4%) Family history of aneurysms 9 (14.8%) Smoking History Never smokers 26 (42.6%) Past smokers 13 (21.3...

O-005 Comparison of on-label versus off-label treatment of intracranial aneurysms with the pipeline embolization devices
ConclusionIn real-world practice, off-label uses of PED can achieve similar safety and efficacy to on-label uses, though there may be a slightly higher rate of ischemic complications in off-label uses. Expert judgment is a useful supplement to official guidelines when assessing reasonable PED use beyond its approved indications.Disclosures S. Cler: None. D. Lauzier: None. A.
