Intended Bridging Therapy or Intravenous Thrombolysis Alone in Minor Stroke With Basilar Artery Occlusion

Abstract : Background and Purpose: Whether bridging therapy (intravenous thrombolysis [IVT] followed by mechanical thrombectomy) is superior to IVT alone in minor stroke with basilar artery occlusion remains uncertain. Methods: Multicentric retrospective observational study of consecutive minor stroke patients (National Institutes of Health Stroke Scale score ≤5) with basilar artery occlusion intended for IVT alone or bridging therapy. Propensity-score weighting was used to reduce baseline between-groups differences, and residual imbalance was addressed through adjusted logistic regression, with excellent outcome (3-month modified Rankin Scale score 0–1) as the dependent variable. Results: Fifty-seven patients were included (28 and 29 in the bridging therapy and IVT alone groups, respectively). Following propensity-score weighting, the distribution of baseline clinical and radiological variables was similar across the 2 patient groups, except age, posterior circulation Alberta Stroke Program Early CT Score, history of hypertension and smoking, and onset-to-IVT time. Compared with IVT alone, bridging therapy was associated with excellent outcome (adjusted odds ratio=3.37 [95% CI, 1.13–10.03]; P =0.03). No patient experienced symptomatic intracranial hemorrhage. Conclusions: Our results suggest that bridging therapy may be superior to IVT alone in minor stroke with basilar artery occlusion.
