Empowering EVAR: Revolutionizing Patient Understanding and Qualification with 3D Printing.

Background: This study addresses the need for enhanced patient education in the context of abdominal aortic aneurysm (AAA) and its treatment through endovascular aneurysm repair (EVAR). Effective patient education is essential for improving comprehension and engagement, particularly for those facing complex medical conditions.

Methods: A total of 55 patients scheduled for EVAR participated in the study. Patient-specific three-dimensional (3D)-printed models of the participants' aneurysms were created using computed tomography angiogram (CTA) scans. The educational intervention included a structured session utilizing these 3D models, with assessments conducted before and after the session, including the Mini-Mental State Examination (MMSE). Statistical analyses evaluated the knowledge gain and its correlation with cognitive function.

Results: The results showed a significant increase in knowledge scores post-education (p < 0.001), with a mean knowledge gain of 2.36 points. Patients rated the effectiveness of the 3D models highly on a Likert scale, with a mean score of 4.64 for improving their understanding of the medical condition and procedural aspects. A weak correlation was observed between MMSE scores and knowledge test results.

Conclusions: This study demonstrates the potential of patient-specific 3D models to enhance patient education in the context of EVAR, improving patients' understanding of their medical condition and the procedure and thereby facilitating more informed decision-making.
