Abstract

Objectives: To evaluate the safety and efficacy of endovascular therapy in elderly adults treated for acute ischemic stroke. Design: Retrospective cohort study. Setting: Comprehensive Stroke Center, University of Tor Vergata, Rome, Italy. Participants: Elderly adults treated for acute ischemic stroke (N = 219). Measurements: Participants were divided into two groups based on their age (n = 62, ≥80; n = 157, <80). Baseline and procedural characteristics, safety outcomes such as intracranial hemorrhage (ICH) and mortality and efficacy outcomes such as successful reperfusion and 3-month good clinical outcome of the two groups were compared. Mutivariable analysis was performed to identify predictors of clinical outcome. Results: Intravenous thrombolysis was more frequent (67.7% vs 52.8%, P =.04), and onset to reperfusion time was shorter (318.7 ± 128.7 vs 282 ± 53.5, P =.02) in participants aged 80 and older, but no between-group differences were found in terms of successful reperfusion (69% vs 63%, P =.4), good clinical outcome (30.6% vs 34.3%, P =.6), any (37% vs 37.5%, P >.99) or symptomatic (11% vs 14%, P =.6) ICH, or mortality (40.3% vs 29.2%, P =.14). Multivariable analysis revealed that, in the older group, onset National Institute of Health Stroke Scale (NIHSS) score (odds ratio (OR) = 0.65, 95% confidence interval (CI) = 0.44–0.96, P =.03) and 24-hour clinical improvement (OR = 141.13, 95% CI = 2.96–6,720.7, P =.01) were independent predictors of 3-month functional independence. Conclusion: These findings suggest that endovascular treatment for stroke in selected elderly adults could be safe and effective. Major determinants of outcome in this subgroup of elderly patients are presentation NIHSS score and 24-hour clinical improvement.
