E-204 Outcomes of radial and femoral access in mechanical thrombectomy for posterior circulation occlusions: a multicenter propensity-adjusted analysis

In this study, we compare outcomes for radial and femoral access for MT in posterior circulation strokes.MethodsA retrospective analysis of all patients with a posterior circulation large vessel occlusion whom underwent mechanical thrombectomy at two large comprehensive stroke centers was performed. Data on demographics, clinical presentation, procedural data, including radial or femoral access, and outcomes were tabulated. Outcomes of interest included National Institute of Health Stroke Scale at discharge and 24-hours. The Thrombolysis in Cerebral Infarction (TICI) scale was used to ascertain revascularization after intervention. Operative time and hospitalization duration were also investigated. Univariate analysis relied on the Mann-Whitney Test, and Chi-square test. Multivariate analysis utilized propensity adjustments in Firth’s logistic regression for dichotomous outcomes and Poisson regression for continuous outcomes. A propensity adjustment was performed for the following variables: gender, age, admission NIHSS, ASPECT, presence of basilar, vertebral lesion, side of entry, tandem occlusion, stent/stent-retriever, pre-hospital anticoagulation or antiplatelet, and TPA usage.ResultsSixty-five patients were included in analysis, 50 (77%) of which had femoral access. 42% of femoral patients received TPA, whereas 6.7% of radial patients received TPA (p = 0.026). 94% of femoral patients had basilar occlusion, compared to 66.7% of radial patients (p = 0.017). Stent-Ret...
