Abstract:
Objective:To investigate the risk factors for 90 d death after endovascular mechanical thrombectomy (MT) in patients with acute anterior circulation large-artery occlusive stroke.Methods:From October 2015 to March 2018, patients with acute anterior circulation large-artery occlusive stroke treated with MT in People's Hospital of Shanghai Pudong New Area and the Second Affiliated Hospital of Soochow University were enrolled retrospectively. The primary outcome events were defined as death within 90 d after operation. Univariate and multivariate logistic regression models were used to identify the independent risk factors for death within 90 d after operation. Results:A total of 116 patients were enrolled, 23 (19.8%) of them died within 90 d after operation. Univariate analysis showed that there were significant differences in age, baseline National Institutes of Health Stroke Scale (NIHSS) score, the Alberta Stroke Program Early CT Score (ASPECTS), and the proportion of the baseline NIHSS score classification (≤8, 9-15, ≥16), ASPECTS ≤7, the number of attempts to pass >3 times, modified Thrombolysis in Cerebral Infarction (mTICI) blood flow grade 2b/3, hemorrhagic transformation (HT), and symptomatic HT in the death group compared with the survival group (all P<0.05). Multivariate analysis showed that after adjusting for age, fasting blood glucose, baseline NIHSS score, number of attempts to pass >3, and mTICI grade 2b/3, lower ASPECTS (odds ratio [ OR] 0.647, 95% confidence interval [ CI] 0.456-0.917; P=0.014), longer time from onset to vascular recanalization ( OR 1.004, 95% CI 1.000-1.007; P=0.046) and symptomatic HT ( OR 13.522, 95% CI 2.719-67.258; P=0.001) were the independent predictors of death within 90 d. Conclusion:The ASPECTS, time from onset to recanalization, and symptomatic HT were the independent risk factors for death within 90 d after MT in patients with acute anterior circulation large-artery occlusive stroke.
