P162/231 Good Clinical Outcome Decreases With Number of Retrieval Attempts in Posterior Circulation Stroke Thrombectomy
ConclusionSuccessful reperfusion within the first three retrieval attempts is associated with improved clinical outcome compared to patients without reperfusion. We conclude that at least three retrieval attempts should be performed in EVT of posterior circulation strokes.Disclosure of InterestDr Thomall: personal fees from Acandis, grants and personal fees from Bayer, personal fees from Bristol Myers Squibb/Pfizer, Boehringer Ingelheim, Daiichi Sankyo, Portola, Stryker outside the submitted work.

P164/236 Antithrombotic regimen in emergent carotid stenting for acute ischemic stroke due to tandem lesion: a meta-analysis of aggregate data
ConclusionsIn AIS due to tandem occlusion, the periprocedural antithrombotic regimen of eCAS seems to have a marginal effect on good functional outcome. Overall, high intensity antithrombotic therapy may provide a marginal benefit on good functional outcome and carotid stent patency without a significant increase in risk of sICH.Disclosure of InterestNothing to disclose

P170/281 Endovascular thrombectomy with or without thrombolysis bridging in patients with acute ischemic stroke: a systematic review and meta-analysis of randomized trials
ConclusionLow-certainty evidence shows a small possible decrease in functional independence, low-certainty evidence shows a small possible decrease in mortality, and moderate-certainty evidence that there is probably a decrease in sICH for patients with EVT alone compared to EVT plus IVT.Disclosure of InterestThe authors have nothing to disclose.

P174/304 CGuard stent in emergent settings- is the dual-layer stent safe? A multicenter study
ConclusionIn this multicenter study, the use of CGuard for emergent carotid artery stenting, particularly in tandem occlusions, was safe and resulted in lower rates of in-stent occlusions.Disclosure of InterestThe authors stated explicitly that there are no conflicts of interest in connection with this abstract.

P175/308 Analysis of demographic, procedural and imaging data of patients with acute arteriosclerotic tandem lesion: Age and stroke severity matters most for clinical outcome
ConclusionEVT for TL is safe and effective. Lower age and shorter procedural time both correlate with successful outcomes, but the fact that stroke severity, neurological issues and diabetes are linked to higher mortality shows the connotation of comorbidities with long-term survival.Disclosure of InterestAll authors: Nothing to disclose

Rethinking the role of CT perfusion in the management of emergent large vessel ischemic stroke
The treatment of emergent large vessel occlusion (ELVO) was revolutionized by endovascular thrombectomy (EVT). The identification of eligible patients for EVT has sparked significant interest in determining the neuroimaging modality that offers optimal results. The American Stroke Association recommend the use of both non-contrast CT and CT angiogram for patients coming in the early window (0–6 hours).1 In the late window (6–24 hours) the randomized trials, DAWN and DEFUSE 3, showed clinical benefit utilized some form of quantitative estimation of the core infarct.2 3 Consequently the society recommends automat...

Decoding the data: a comment on the American Heart Association/American Stroke Association (AHA/ASA) 2023 Guideline for the Management of patients with Aneurysmal Subarachnoid Hemorrhage
Guideline summary The 2023 Guideline for the Management of Patients With Aneurysmal Subarachnoid Hemorrhage was recently released with endorsements from multiple societies, including the Society of NeuroInterventional Surgery.1 All who worked on this document should be congratulated for their work, as it provides many updates, and addresses new components of aneurysmal subarachnoid hemorrhage (aSAH) care. We encourage providers to thoroughly read the statement. While this Guideline statement is thorough, it is important to highlight opportunities for future research, and gaps in the literature, where rigorous adherence to ...

Modern endovascular management of chronic total carotid artery occlusion: technical results and procedural challenges
Conclusions In the modern endovascular era, revascularization of CTO is a feasible procedure in most cases, and it may be offered in selected patients. However, the high re-occlusion rate is still a limitation of the technique, underlining the need for more research on the technical procedural and periprocedural management.

Retained radial catheters associated with variant radial anatomy in neurointerventional procedures
Conclusion Retained catheters for neurointerventional procedures performed via TRA are rare. However, this complication may be associated with variant radial anatomy. With the increased use of TRA for neurointerventional procedures, awareness of anatomical abnormalities that may lead to a retained catheter is necessary. We propose a simple protocol to avoid catheter entrapment, including in emergent situations such as TRA for stroke thrombectomy.

Alberta Stroke Program Early CT Score and collateral status predict target mismatch in large vessel occlusion with delayed time windows
Conclusions NCCT ASPECTS had a strong correlation with CTP core volumes in patients with LVO-AIS in delayed time windows. Combining NCCT ASPECTS with sCTA-CS resulted in a more accurate prediction of target mismatch. If a CTP scan is not available, NCCT ASPECTS combined with sCTA-CS may guide clinicians in making treatment decisions.
