Introduction Safe and complete treatment of intracranial aneurysm requires a thorough understanding of the complex three-dimensional vascular structure specific to each patient. We introduced a 3D vascular model mixed reality (MR) in endovascular treatment to enhance anatomical confidence.

Aim of Study This study aims to validate the usefulness and feasibility of a MR application in the endovascular treatment of intracranial aneurysms.

Methods Developed an application software called Object Loader using the Unity program, enabling the upload and manipulation of a 3-D vascular model on the Hololens. From September 2021, endovascular procedures were performed on consecutive patients with intracranial aneurysms, utilizing MR assistance. A score system composed of total score 7 was employed to evaluate the merits of MR application in each case.

Results Between September 2021 and March 2023, 54 MR-assisted endovascular treatments were performed on 51 patients. No immediate complications were observed. Favorable occlusion was achieved in 80% of cases. Discrimination of overlapped vasculature and rechecking dangerous regions were the most useful merits.

Conclusion In conclusion, the utilization of mixed reality with a 3-dimensional vascular model digital twin enhanced the anatomical confidence and safety of endovascular procedures for the treatment of intracranial aneurysms. The discrimination of overlapped vascular structures and real-time alarming of the physician regarding dangerous areas during the procedure demonstrated the usefulness of this technology. The continuous evolution of augmented reality has the potential to revolutionize daily procedures.
