Comparison of Two Three-Dimensional Printed Models of Complex Intracranial Aneurysms for Surgical Simulation

The whole and regional 3D printed aneurysm models were accurate. The whole model was more useful for planning the trajectory of approach to the aneurysm when it was located in close proximity to bone and nerves, whereas the regional 3D aneurysm model was appropriate for aneurysms not involving bone and nerves. This will help neurosurgeon choose the proper 3D model for the complex aneurysm surgery according to the comparison.
