AB  - Objectives To identify the occurrence rate and predictors of futile recanalisation after endovascular therapy (EVT) for acute vertebrobasilar artery occlusion (VBAO).Methods Participants of the Endovascular Treatment Key Technique and Emergency Workflow Improvement of Acute Ischaemic Stroke (ANGEL-ACT) registry were selected for the analysis. Futile recanalisation was defined as patients did not achieve a 90-day good outcome (modified Rankin Scale ≤3) despite successful recanalisation (modified Treatment in Cerebral Ischaemia Scale ≥2b) after the procedure. Multivariable logistic regression analysis was conducted to find independent predictors of futile recanalisation in VBAO patients undergoing EVT.Results Three hundred and fifteen patients with VBAO who achieved successful recanalisation after EVT were included in current analysis, of whom, 155 (49.2%) suffered futile recanalisation, and 160 achieved effective recanalisation. After the multivariable analysis, we found admission National Institutes of Health Stroke Scale (NIHSS) ≥19 (OR 4.81, 95% CI 2.76 to 8.39, p<0.001), platelet-lymphocyte ratio (PLR) ≥162.2 (OR 1.93, 95% CI 1.14 to 3.27, p=0.001), onset-to-puncture time (OTP) ≥334 min (OR 2.15, 95% CI 1.25 to 3.68, p=0.005) and use of general anesthesia (GA) (OR 1.87, 95% CI 1.09 to 3.22, p=0.024) were associated with futile recanalisation.Conclusions Futile recanalisation after EVT occurred 49.2% of VBAO patients in the ANGEL-ACT registry. NIHSS≥19, PLR≥162.2, OTP≥334 min and use of GA were independent predictors of futile recanalisation.Data are available on reasonable request.
