Background And Objectives: Previous studies have demonstrated the association between the procedure time (PT) and outcomes for patients with proximal large vessel occlusion; however, whether the relationship remains for patients with acute basilar artery occlusion (ABAO) was not clear. We aimed to characterize the association between PT and other procedure-related variables on clinical outcomes among patients with ABAO who underwent endovascular treatment (EVT).
Methods: Patients with ABAO who underwent EVT with a documented PT in the EVT for Acute Basilar Artery Occlusion (BASILAR) study from January 2014 to May 2019 among 47 comprehensive centers in China were included. Multivariable analysis was performed to reveal the association between PT and 90-day modified Rankin Scale score, mortality, complications, and all-cause death at 1 year.
Results: Of the 829 patients from the BASILAR registry, 633 eligible patients were included. Longer PT were associated with a lower rate of favorable outcome (by 30 minutes, adjusted OR 0.82 [95% CI 0.72-0.93], = 0.01). In addition, a PT ≤ 75 minutes was associated with a favorable outcome (adjusted OR 2.03 [95% CI 1.26-3.28]). The risk of complications and mortality increased by 0.5% and 1.5% with every 10 minutes increase in PT, respectively (R = 0.64 and R = 0.68, < 0.01). The cumulative rates of favorable outcomes and successful recanalization plateaued after 120 minutes (2 attempts). Restricted cubic spline regression analysis for the probability of favorable outcomes had an L-shape association ( nonlinearity = 0.01) with PT with significant benefit loss before 120 minutes and then appeared relatively flat.
Discussion: For patients with ABAO, procedures that exceeded 75 minutes were associated with an increased risk of mortality and lower odds of a favorable outcome. A careful assessment of futility and the risks of continuing the procedure should be made after 120 minutes.

Purpose: This study aimed to analyze the association between different occlusion sites and clinical outcomes in acute basilar artery occlusion (ABAO) patients.
Patients And Methods: This study recruited ABAO patients from the BASILAR registry to evaluate outcomes by occlusion sites (distal, middle and proximal ABAO) and treatment modality. Primary effectiveness outcome was assessed by the modified Rankin Scale (mRS) score 0-3 and secondary effectiveness outcomes were mRS 0-2 and 0-1.

Background: The effectiveness and safety of endovascular therapy (EVT) in patients with Acute Basilar Artery Occlusion (ABAO) with low pc-ASPECTS is unclear.
Objective: To evaluate the effectiveness and safety of EVT in ABAO patients with low pc-ASPECTS.
Methods: We analyzed 199 ABAO patients with pc-ASPECTS ≤ 6 who were prospectively registered in the BASILAR study.

Background: To evaluate the prognostic effect of endovascular treatment (EVT) in patients with acute base artery occlusion (ABAO) within 24 h of onset, and analyze the factors related to prognosis.
Methods: A retrospective analysis was conducted on all ABAO patients who received EVT within 24 h of onset in the neurology department of Baotou Central Hospital in Inner Mongolia from May 2016 to October 2022. Good prognosis was defined as a Modified Rankin Scale (mRS) score of 0-3 and poor prognosis mRS score of 4-6 at 90 day follow-up, and factors related to prognosis were analyzed.

Purpose: Renal impairment (RI) is associated with unfavourable outcome after acute ischaemic stroke with anterior circulation large vessel occlusion. We assessed the association of RI with clinical outcomes in patients with acute basilar artery occlusion (ABAO), and the impact of RI on the effects of endovascular therapy (EVT) versus standard medical treatment (SMT).
Patients And Methods: We used data from the BASILAR registry, an observational, prospective, nationwide study of patients with ABAO in routine clinical practice in China.
