To investigate preoperative anxiety levels and information needs in patients undergoing endovascular treatment for unruptured intracranial aneurysms and to analyze the factors influencing these outcomes.

A total of 190 patients scheduled for endovascular treatment of unruptured intracranial aneurysms at the First Affiliated Hospital of Nanjing Medical University were selected using a convenience sampling method. Data were collected using a self-designed general information questionnaire and the Amsterdam Preoperative Anxiety and Information Scale (APAIS).

The mean preoperative anxiety score was 10.12±2.63, with 31.58% (44/140) of patients scoring ≥12, indicating clinically significant anxiety. The mean information needs score was 6.62±1.52, with 62.63% (88/140) of patients scoring ≥5, reflecting a moderate or higher need for information. A significant positive correlation was found between preoperative anxiety and information needs (P<0.01). Multivariate linear regression analysis identified age, primary caregiver status (i.e., patients responsible for caregiving), and higher information needs as key factors influencing preoperative anxiety. Factors influencing information needs included medical costs, number of children, anesthesia classification, gender, preoperative sleep quality, and prior surgical experienc.

Patients undergoing endovascular treatment for unruptured intracranial aneurysms exhibit high levels of preoperative anxiety and information needs, with a significant positive correlation between the two. Analysis of influencing factors highlights the importance of tailored interventions. Healthcare providers should focus on enhanced information provision and psychological support, particularly for female patients, those with high information needs, poor preoperative sleep quality, and distressing prior surgical experiences, to reduce preoperative anxiety.
