This study aimed to assess the efficacy and safety of direct endovascular treatment (EVT) and bridging IVT followed by EVT in Chinese patients with acute basilar artery occlusion BAO.Methods This subanalysis derived from the prospective multicenter randomized controlled trial of the ATTENTION study, included 221 patients with acute BAO categorized into two groups based on whether they received bridging IVT before MT: MT alone or combined IVT+MT. The primary endpoint was the modified Rankin Scale (mRS) score distribution at 90 days. Secondary outcomes included mRS scores within different ranges (0–1, 0–2, and 0–3) at the 90-day point and National Institutes of Health Stroke Scale (NIHSS) scores at 24 hours and 3 days post-intervention. Safety outcomes encompassed intracranial hemorrhage incidence based on the Heidelberg classification criteria (any intracerebral hemorrhage) and mortality assessment at 90 days.Results Direct and bridging IVT before EVT yielded similar primary outcomes. No significant difference in 90-day mRS scores (median, 4.5 vs 4; adjusted odds ratio (aOR), 0.95 [95% confidence interval (CI), 0.79 to 1.15]; p=0.624) was observed between the two groups. Regarding safety outcomes, no significant differences were observed between the groups in terms of death within 90 days or any intracranial hemorrhage within 24 hours.Conclusions In patients with acute BAO, those treated with bridging IVT before EVT did not demonstrate any advantages in enhanced safety and efficacy outcomes compared with those treated with direct EVT.Data are available upon reasonable request.
