Abstract:
Objective To investigate the relationship between pre-treatment collateral circulation and long-term clinical outcomes in patients with acute vertebrobasilar artery occlusion(VBAO)undergoing endovascular treatment(EVT).Methods A retrospective analysis was conducted on 129 VBAO patients who underwent EVT.Patients were categorized into short-term(90 d)and long-term(1 year)outcome groups based on follow-up duration.Clinical data were collected,and the posterior circulation collateral score(PC-CS)based on magnetic resonance angiography(MRA)was evaluated.Inter-rater reliability of the MRA PC-CS was evaluated using Cohen's Kappa coefficient.The predictive value of MRA PC-CS for outcomes was analyzed using receiver operating characteristic(ROC)curves.Multivariate logistic regression analysis was employed to identify independent predictors of long-term outcomes.Results A total of 109 patients were included in the long-term follow-up,with 78 survivors and 31 deaths.The MRA PC-CS demonstrated high diagnostic efficacy for predicting long-term outcomes,with an area under the curve(AUC)of 0.85[95%confidence interval(CI)0.78-0.92,P＜0.000 1],with an optimal cutoff value of 5 points.Multivariate logistic regression analysis revealed that age[odds ratio(OR)1.07,95%CI 1.02-1.13,P=0.005],admission National Institutes of Health Stroke Scale(NIHSS)score(OR 1.08,95%CI 1.02-1.14,P=0.01),occipital lobe infarction(OR 3.96,95%CI 1.25-12.56,P=0.02),and MRA PC-CS≤5 points(OR 0.23,95%CI 0.06-0.84,P=0.03)were independent predictors of long-term outcomes.Conclusion The MRA PC-CS can independently predict adverse long-term functional outcomes in VBAO patients.
