E-103 Transradial carotid stenting using a 6 french simmons-2 guide catheter in comparison to transfemoral approach: a single center experience
ConclusionsTransradial carotid stenting using lower profile technique appears to be a safe, effective, and faster option for carotid revascularization compared to traditional transfemoral approach although conversion rate may be high which can be mitigated through proper case selection.Disclosures M.

Mechanical thrombectomy is cost-effective versus medical management alone around Europe in patients with low ASPECTS
Conclusions MT is efficient versus MM alone for patients with low ASPECTS in eight countries across Europe. Patients with a large ischemic core could be treated with MT because it is both clinically beneficial and economically sustainable.

Poor clinical outcome despite successful basilar occlusion recanalization in the early time window: incidence and predictors
Conclusions Early successful reperfusion with EVT occurred in 80.5% of patients, and the only treatment-related factor predictive of clinical outcome was first pass mTICI 2b-3 reperfusion. Further research is warranted to identify the optimal techniques and devices associated with first pass reperfusion in the posterior circulation.

Thrombectomy in basilar artery occlusions: impact of number of passes and futile reperfusion
Conclusions We found that BAO patients had a significant relationship between the number of MT passes and both recanalization and favorable functional outcome. We further found that the benefit of recanalization in BAO patients was significant only when recanalization was achieved within three passes, encouraging at least three passes before stopping the procedure.

Patient and aneurysm factors associated with aneurysm recanalization after coiling
Conclusions Several factors are identified by the ARETA study as playing a role in aneurysm recanalization after coiling: current smoking, aneurysm status (ruptured), aneurysm size (≥10 mm), neck size (wide neck), and aneurysm location (middle cerebral artery). This finding has important consequences in clinical practice. Trial registration number URL: http://www.clinicaltrials.gov; Unique Identifier: NCT01942512.

O-042 Incidence of periprocedural stroke with radial access for diagnostic cerebral angiograms
ConclusionIn our experience, transradial access for diagnostic cerebral angiograms was associated with a low but not neglectable incidence of periprocedural strokes when compared to the traditional femoral approach. Patient vascular anatomy should be evaluated prior to selection of vascular access and patients should be made aware of the possibility of a slightly higher possibility of periprocedural stroke with transradial access.Abstract O-042 Table 1 Patient Age Access Vessels catheterized Catheter used Radial Medication Contrast Fluoro Time Platelet Count INR GFR COVID Status Stroke Symptoms NIHSS Imaging performed 1 5...
