Abstract
Purpose
Acute vertebrobasilar artery occlusion (VBAO) is a catastrophic disease for patients. There is evidence that the eventual patient outcome depends on patient-specific and procedural factors. This study aimed to identify the incidence and independent predictors of the 90-day poor outcome in VBAO after endovascular treatment (EVT).
Methods
Subjects were selected from the ANGEL-ACT registry. The 90-day poor outcome was defined as a 90-day modified Rankin Scale (mRS) of 4 to 6. Logistic regression analyses were performed to determine the independent predictors of the 90-day poor outcome.
Results
Of the 347 enrolled patients with acute VBAO undergoing EVT, 176 (50.7%) experienced the 90-day poor outcome. Multivariate logistic regression indicated that only the use of general anesthesia (GA) (odds ratio [OR] = 2.04; 95% confidence interval [CI], 1.23–3.37; P = 0.006) and heparin during the procedure (OR =1.74; 95% CI, 1.06–2.86; P = 0.028), admission National Institute of Health Stroke Scale (NIHSS) ≥ 26 (OR=3.96; 95% CI, 2.37–6.61; P < 0.001), and time from onset to puncture (OTP) ≥ 395 min (OR=1.91; 95% CI, 1.14–3.20; P = 0.014) and procedure duration ≥ 102 min (OR = 1.70; 95% CI, 1.04–2.79; P = 0.036) were independent predictors of the 90-day poor outcome after EVT. Furthermore, admission NIHSS (OR > 36 vs. ≤ 11 = 9.01, P for trend < 0.001), OTP (OR > 441min vs. ≤ 210 min = 2.71, P for trend = 0.023), and procedure duration (OR > 145 min vs. ≤ 59 min = 2.77, P for trend = 0.031) were significantly associated with increasing risk of the 90-day poor outcome.
Conclusions
Poor outcome after EVT at 90 days occurred in 50.7% of acute VBAO patients from the ANGEL-ACT registry. Our study found several predictors of the 90-day poor outcome which should be highly considered in daily practice to improve acute VBAO management.
