Objective: To investigate the incidence, risk factors, and duration-associated factors of delirium after mechanical thrombectomy for acute ischemic stroke.
Methods: This single-center retrospective study included 247 patients who underwent mechanical thrombectomy at our institution between 2019 and 2023. Multivariable logistic and linear regression were performed to identify the risk factors and factors associated with the duration of delirium, respectively.
Results: In this cohort, the incidence of delirium was 25.5%. Older age, benzodiazepine use, and nocturnal insomnia were identified as independent risk factors for delirium. The Thrombolysis in Cerebral Infarction (TICI) score and daily rehabilitation duration were identified as factors that were potentially associated with delirium.
Conclusion: Delirium occurred in 25.5% of patients who underwent mechanical thrombectomy after acute ischemic stroke, and was associated with older age, benzodiazepine use, and nocturnal insomnia. In contrast, successful reperfusion and longer rehabilitation duration were potentially associated with delirium among these patients.
