Background: Understanding sex disparities in stroke can identify gaps in clinical care. The objective of this study was to investigate whether sex differences could influence clinical outcomes of patients with acute vertebrobasilar artery occlusion (VBAO) who underwent endovascular therapy (EVT). Methods: Patients were selected from the ANGEL-ACT Registry. The primary outcome was favorable functional outcome (90-day modified Rankin Scale [mRS] 0–3). Secondary outcomes included 90-day mRS distribution, excellent outcome (mRS 0–1), functional independence (mRS 0–2), early neurological improvement, recanalization, intracranial hemorrhage, and mortality within 90 days. The above outcomes were compared by two adjustment models, including (1) multivariable logistics analysis adjusting for all baseline and procedural variables with a P < 0.05; (2) adjusting for the propensity score. Results: There were 347 acute VBAO patients treated with EVT included, of whom 72 (20.7%) were women and 275 (79.3%) were men. Women were older (72[63–76] vs. 62[53–69], P < 0.001) and had a higher rate of atrial fibrillation (31.9% vs. 8.7%, P < 0.001), lower rates of underlying intracranial atherosclerotic disease (30.6% vs. 51.3%, P = 0.007), and tandem occlusion (8.3% vs. 21.8%, P = 0.009) than men. The rate of favorable outcome (mRS 0–3) was similar between women and men (41.7% vs. 51.3%, adjusted odds ratio 1.56, 95%CI: 0.83–2.95, P = 0.171). There were no sex differences in other clinical outcomes (all P > 0.05). Conclusions: In the ANGEL-ACT registry, the percentage of men with acute VBAO undergoing EVT was approximately fourfold higher than that of women with acute VBAO undergoing EVT. Sex differences did not modify the outcomes of acute VBAO after EVT. [ABSTRACT FROM AUTHOR]

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.
