Abstract

BackgroundAlthough endovascular treatment (EVT) has become the standard treatment for acute large vessel occlusion (LVO), its safety and efficacy in older adults have not been fully determined. The present study aimed to compare the safety and efficacy of EVT for acute LVO between younger (<80 years old) and older adults (≥80 years old) in the Chinese population.MethodsThe subjects were selected from the ANGEL-ACT registry (endovascular treatment key technique and emergency workflow improvement of acute ischemic stroke). The 90-day modified Rankin score (mRS), successful recanalization, procedure duration, number of passes, intracranial hemorrhage (ICH), and mortality within 90 days were compared after adjusting for confounders.ResultsA total of 1,691 patients, 1,543 classified as young and 148 classified as older, were included. We observed that young and older adults had a similar 90-day mRS distribution, successful recanalization, procedure duration, number of passes, ICH, and mortality within 90 days (all p > 0.05). The rate of 90-day mRS 0–3 was found to be higher in young patients than in older adults (39.9% vs. 56.5%, odds ratio = 0.64, 95% confidence interval = 0.44–0.94, p = 0.022).ConclusionWe found that patients less than or greater than 80 years of age share similar clinical outcomes, without increasing the risk of ICH and mortality.
