Abstract
Background Acute basilar artery occlusion is a disabling and life-threatening condition. The purpose of this study was to evaluate the impact of occluded vessel location on the prognostic outcomes of patients who underwent endovascular treatment for acute basilar artery occlusion.
Methods Patient data for this study were obtained from the ATTENTION registry. Baseline data of the patients were described and compared across different occlusion locations. Univariable and multivariable regression analyses were performed to assess the effect of occluded vessel location on associated prognostic outcomes.
Results A total of 1672 patients were included in the analysis, with 583 having distal occlusion, 540 having middle occlusion, and 549 having proximal occlusion. Unlike distal occlusion, both proximal and middle occlusions were significantly and negatively associated with favorable clinical outcomes (for modified Rankin Scale score 0–3: adjusted odds ratio (aOR) 0.634, 95% confidence interval (95% CI) 0.493 to 0.816, P<0.001 in middle occlusion, and aOR 0.620, 95% CI 0.479 to 0.802, P<0.001 in proximal occlusion). Mortality was higher in patients with proximal and middle occlusions (aOR 1.461, 95% CI 1.123 to 1.902, P=0.005 in middle occlusion, and aOR 1.648, 95% CI 1.265 to 2.147, P<0.001 in proximal occlusion). The occluded vessel location was not associated with symptomatic intracranial hemorrhage.
Conclusions Proximal and middle basilar artery occlusions were predominantly associated with poor clinical outcomes and increased risk of death following endovascular treatment.
