%X <B>BACKGROUND: </B>Age is often used as a predictor in determining outcomes in large vessel occlusions treated with mechanical thrombectomy. However, limited data exist for octo/nonagenarian outcomes compared to younger individuals in acute basilar artery occlusions treated with thrombectomy.<BR><B>METHODS: </B>Patient data were obtained from the PC-SEARCH Thrombectomy Registry which consists of 444 acute basilar artery occlusions treated with mechanical thrombectomy. Individuals were dichotomized based on age (>80 and ≤80 years old). Primary outcome was defined as modified Rankin Scale of 0-3 at 90 days. Logistic and multivariate regression, as well as control-matched analysis, were performed.<BR><B>RESULTS: </B>There were 373 and 71 patients in the younger and older cohorts, respectively. Gender, ethnicity, smoking status, atrial fibrillation, and coronary artery disease were noted to be significantly different between cohorts. At 90 days, 178 (47.7%) and 23 (32.4%) patients achieved primary outcome at 90 days (p = 0.02), however, after controlling for potentially confounding factors this association lost significance (OR 0.50 95% CI 0.24-1.05; p = 0.07). There were 84 patients included in the control matched analysis and demonstrated no significant differences on multivariate analysis between cohorts (OR 0.68 95% CI 0.25-1.84; p = 0.45).<BR><B>CONCLUSIONS: </B>Octa/nonagenarians presenting with an acute basilar artery occlusion treated with mechanical thrombectomy can achieve acceptable rates of favorable functional outcomes compared to younger individuals with similar baseline demographic and stroke characteristics.
