Abstract:Objective To investigate the profile characteristics and influencing factors of the potential category of dysfunction after endovascular treatment in middle-aged and elderly patients with intracranial aneurysms.Methods This study was a cross-sectional survey. A total of 116 middle-aged and elderly patients with intracranial aneurysms admitted to our hospital from January to September 2024 were convenient selected. The general information questionnaire, the Outgoing Disorders Scale, the Exercise Self-Efficacy Scale, the Psychological Distress Scale, and the Social Support Scale were used to investigate. The latent profile analysis was used to identify the potential types of outgoing disorders in middle-aged and elderly patients with intracranial aneurysms after EVT.Multivariate Logistic regression analysis was used to evaluate the influencing factors of different potential categories.Results There was a potential profile of post-EVT exodus disorder in middle-aged and elderly patients with intracranial aneurysms, including high exodus disorder-insecurity ( 22 cases, 19 % ), middle exodus disorder-social relationship deficiency ( 63 cases, 54 % ), low exodus disorder ( 31 cases, 27 % ). The results of multi-category Logistics analysis showed that housing type, ESES score, DT score and social support degree were the influencing factors of out-migration disorder after EVT in elderly patients with intracranial aneurysms in different profiles ( P < 0.05 ).Conclusion There are certain individual differences in the level of out-migration barriers in elderly patients with intracranial aneurysms after EVT, which can be divided into three potential categories : high out-migration barriers-lack of security, middle out-migration barriers-lack of social relations, and low out-migration barriers. It is related to housing type, exercise self-efficacy, psychological distress, social support and other factors. Medical staff can formulate targeted interventions based on influencing factors.
