Patients who will undergo a intracranial aneurysm (IA) surgery are educated concerning their disease and the surgical procedure.The objective of this study is to explore the advantages of conventional, virtual reality and 3D stereolithographic models for patient and resident education in the treatment of lAs.
Patient understanding of their medical condition and treatment satisfaction has gained increasing attention in medicine. As for neurosurgical conditions however, the treatment plan is often difficult for patients to comprehend, with many of them having an inaccurate understanding of the involved anatomy.
Novel technologies therefore may play a role in facilitating patient education. In particular, conventional 2D images makes it sometimes difficult for surgeons to inform their patients about the planned intervention and potential complications. This is why new modalities have been developed for patient information and may have further an impact on resident education to better estimate the treatment plan and potential complication. For the latter, given that intracranial aneurysms (lAs) are increasingly treated via endovascular methods, training opportunities are reduced and understanding of the vascular anatomy can become difficult.
The objective of this study is to explore the advantages of conventional, virtual reality and 3D stereolithographic models for patient and resident education in the treatment of lAs.

| Questionnaire and use of 3 D tools | Procedure | Resulting computer tomography(CT) results are transferred to a 3 D projection. Patients will be asked to wear 3 D glasses to be able visualizing the diagnosed vascular pathology. The physician will explain the disaese and treatment. The patient is ask to fill out a questionnaire post 3D consulting |
| Measure | Description | Time Frame |
|---|---|---|
| accuracy of the planned intervention and clip placement. | Assessment of the 3D models regarding the accuracy of the planned intervention. In specific the following surgical steps are evaluated and assessed during aneurysm clipping and compared to the ideal preoperative forecast based on the 3D model (GRF_clip anticipation): Temporary clips: (1) number of temporary clips; (2) left- or right-handed application; (3) position on parent artery; (4) length of the clip; (5) shape of the clip. Permanent clips: (6) number of permanent clips; (7) left- or right-handed application; (8) length of the clip; (9) shape of the clip. | 6 months post interventional |
| Measure | Description | Time Frame |
|---|---|---|
| patient education | Assessment of ischemia (large and perforating artery compromise), time of temporary clip occlusion, morbidity, clinical outcome., To investigate the impact of personalized 3D printed model on patient information before surgery, study participants will be presented with their individual 3D printed model and a questionaire to analze an improvement in their understanding of basic anatomy, the planned surgical procedure, and understanding the complications related to the surgery will be assessed (GRF_patient satisfaction). To further determine if 3D printed models can be used to improve intraoperative pattern recognition and be a valuable adjunct in neurosurgical resident education, a comparison of conventional imaging with CT-scan, 3D-RA, 3D model will be assessed (GRF_resident education). |

The study population are patient with a age >18 years, diagnosed with a intracranial aneurysma , requiring surgery. The eligibility is evaluated and prior surgery, preoperative assessment by CTA and 3D-DSA have been performed. After screening a non routine consultation with the 3 D method visualization is scheduled. Finally, patients will be scheduled for surgery according to our standard procedure.
