E-115 Trans-radial versus trans-femoral access routes for diagnostic cerebral angiograms: a large single-center comparative cost-analysis study
ConclusionOverall, our study shows that the TR approach can be less a less expensive option for patients undergoing diagnostic cerebral angiograms, especially if complications occur. Future studies can corroborate our findings and potentially lead to the adoption of TR as a low-cost, efficient, gold-standard technique for cerebral angiography.Costs (dollars) Associated with Trans-Radial Versus Trans-Femoral AccessAbstract E-115 Table 1 Variable Trans-Femoral (n=314) Trans-Radial(n=612) P-value Total Cost, mean (SD) 12591.8 (19128) 12789.5 (18424) .88 Catheters, median (range) 12.4 (12.4-1900) 55.2 (12.4-369) .03 Closure d...

E-142 A new graphical interface to capture quantitative venous outflow metrics
ConclusionsOur newly developed graphical interface allows users to output quantitative metrics that may represent AIF and VOF. These metrics should be checked against existing scales for association and performance.Abstract E-142 Figure 1Disclosures G. Adusumilli: None. S. Christensen: 2; C; iSchemaView. 4; C; iSchemaView.

E-164 Symptomatic developmental venous anomaly thrombosis associated with covid-19 infection
We describe a milder case of DVA thrombosis in the setting of COVID-19 infection presenting with unilateral hemiparesis requiring medical management alone. A 41-year-old female with hypertension who presented with left hemiparesis. Non-contrast computed tomography (CT) of head revealed linear calcifications in the right centrum semiovale consistent with DVA. Magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the right corona radiata adjacent to the vascular abnormality. Extensive workup for other causes of ischemic stroke was unrevealing. Cerebral angiography ruled out arteriovenous shunting and did not ...

O-017 Viz LVO versus rapid LVO in detection of large vessel occlusion on computed tomography angiography for acute stroke
ConclusionViz LVO and Rapid LVO had similar NPV, but Rapid LVO produced a significantly larger number of false positive values. False positive values can be a source of alarm desensitization, leading to missed alarms or delayed responses. EF and intracranial atherosclerosis were significant predictors of incorrect predictions in both software packages. We hope this data will be used to improve future algorithms.Disclosures A.

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.

E-212 A comparison of outcomes between transfemoral versus transradial access for carotid stenting
ConclusionThe TR approach is safe, feasible, and provides similar rates of complications and high rates of successful stent deployment compared with the TF route. Neurointerventionalists adopting the radial first approach should carefully assess the pre-procedural computed tomography angiography to identify patients amenable to TR approach for carotid stenting.Abstract E-212 Table 2Comparison of outcomes between trans-radial vs trans-femoral access Outcome Trans-Femoral (n=232) Trans-Radial(n=110) Odds Ratioβ(95% CI) p-valueβ Odds Ratio*(95% CI) p-value* Primary Outcome: Any Complication, n (%) 15 (6.5%) 3 (2.7%...

E-029 Thrombectomy in stroke patients with low ASPECTS: is TICI 2C/3 superior to TICI 2B?
ConclusionIn patients with low ASPECTS, achieving a TICI 2C/3 score after MT is associated with a more favorable 90-day outcome. These findings suggest that TICI 2C/3 is a better target for MT than TICI 2B in patients with low ASPECTS.Abstract E-029 Figure 1Disclosures S. Samir Elawady: None. M. Mahdi Sowlat: None. I.

Case report: Mechanical thrombectomy for acute basilar artery occlusion via persistent hypoglossal artery
Persistent hypoglossal artery (PHA) is a rare carotid-vertebrobasilar anastomosis in adults. Here, we report a case of mechanical thrombectomy for acute basilar artery occlusion via the PHA. A 44-year-old man was admitted to our stroke unit with an unstable gait and aphasia for 2 h. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 4, but the clinical symptoms continued to worsen. Computed tomography angiography showed the absence of the basilar artery and an abnormal anastomosis between the anterior and posterior circulation. Clinical symptoms continued to worsen, and endovascular treatment was sch...

Direct current cardioversion practices following percutaneous left atrial appendage closure
DiscussionThere is a widely varied practice pattern of TEE, CCTA, and OAC use with DCCV after LAAC, with a 6% rate of LAT/DRT. LAA imaging before DCCV appears prudent in all cases, especially within 1 year of LAAC, to assess for device position, PDL, and LAT/DRT.
