Rates of operative intervention for infection after synthetic or autologous cranioplasty: a National Readmissions Database analysis
CONCLUSIONS: SFs are increasingly replacing ABFs as the material of choice for cranioplasty, despite their association with increased hospital charges. Female sex, nonroutine discharge, and SF cranioplasty are associated with increased risk for reoperation after cranioplasty.PMID:35901766 | DOI:10.3171/2022.4.JNS22301

E-038 Stroke registries and publication metrics in relation to registration and industry sponsorship
ConclusionsStroke registries generate a substantial amount of publications and citations in literature. Approximately two-thirds of all publications do not reach their expected number of citations. Those registered at clinicaltrials.gov have fewer citations than their unregistered counterparts. Industry-sponsored registries have a higher impact factor, reflecting their publications in more prominent journals, but are less cited than non-sponsored ones.Disclosures W. Khawar: None. A.

E-040 Factors associated with failed mechanical thrombectomy in acute ischemic stroke
ConclusionFailed MT was encountered in approximately 12% of cases. The most common location of failed MT was intracranial and this was predominantly due to ICAS. Further studies to evaluate better treatment modalities of ICAS related LVO are warranted.Disclosures O. Lajthia: None. H. Ali: None. R. Neyes: None. E. Almallouhi: None. R. Chalhoub: None. K.

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-147 Ephrin receptor beta 1 single nucleotide polymorphisms in association with age in acute stroke patients undergoing thrombectomy
Conclusion193 patients were included in this interim analysis across 23 centers in the United States, between 02/2021 and 11/2021. For the EPHB1 SNP (rs13073658), Table 1 shows the numbers and proportions of patients with varying expressions of the SNP. While no patients 50 or older were homozygous for the SNP, 16% of those under 50 years old were. The potential relationship between EPHB1 SNP and stroke in younger patients requires further evaluation.Abstract E-147 Table 1Disclosures J.

O-007 First US multicenter experience using the pipeline flex embolization device with shield technology for treatment of intracranial aneurysms - periprocedural outcomes and early safety profile
ConclusionOur study is the first to report the early experience with the newly FDA-approved PED Flex with Shield technology amongst US centers. Our results are comparable with non-US, international studies showing a high technical success rate and safe peri-procedural angiographic and patient outcome. Long-term follow-up will be needed to provide more robust data on angiographic and patient outcomes.Disclosures A. Kuhn: None. J. Singh: None. A. Abdelsalam: None. V. Saini: None. J. Burks: None. G.

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...

P-013 Designing and prototyping a novel balloon-stent device for minimally invasive temporary aneurysm occlusion and embolization
ConclusionA balloon-stent device allows for longer neuro-interventional procedures by providing continuous perfusion without arresting blood flow during balloon inflation. In addition, this novel medical device provides a smooth surface at the aneurysm neck for consistent device placement, minimization of parent vessel trauma, elimination of ischemic effects distal to the parent artery, and minimization of intra-saccular flow remnants pre- and post-treatment.Abstract P-013 Figure 1a) FPR results from theoretical estimation, benchtop modeling, and computational fluid dynamic (CFD) simulation.

P-017 Triple therapy versus dual antiplatelet therapy for dolichoectatic vertebrobasilar fusiform aneurysms treated with flow-diverters: the last frontier?
ConclusionsPatients with dolichoectatic VBFAs treated with flow-diversion and kept under triple therapy had less ischemic strokes, less progression of symptoms and overall better outcomes at last follow-up than similar patients kept under DAPT.Disclosures A.
