Clipping of cerebral aneurysms is an important skill in neurosurgery. However, as the number of clipping procedures is decreasing, young neurosurgeons have insufficient experience with cerebral aneurysms. Therefore, a training model for clipping is needed. Here, we present a training model for cerebral aneurysm clipping. The concepts underlying the model were 1: creating a cerebral aneurysm clipping training model for beginners, 2: three-dimensional (3D) manipulation in a deep operating field using an operating microscope, 3: 3D data simulation of the anatomical relationship between the aneurysm and surrounding tissue. Skull, brain, arteries, and veins were produced using a 3D printer based on DICOM data. Skull, brain, and vessels were made of polyvinyl alcohol (PVA). The characteristic softness of the brain and vessels was reproduced. Thus far, six training courses have been conducted, and the trainees were overall satisfied with the training, according to a survey. This model is useful for training young neurosurgeons in cerebral aneurysm surgery.
