Prototyping of cerebral vasculature physical models

Surg Neurol Int. 2014 Jan 27:5:11. doi: 10.4103/2152-7806.125858. eCollection 2014.


Background: Prototyping of cerebral vasculature models through stereolithographic methods have the ability to accurately depict the 3D structures of complicated aneurysms with high accuracy. We describe the method to manufacture such a model and review some of its uses in the context of treatment planning, research, and surgical training.

Methods: We prospectively used the data from the rotational angiography of a 40-year-old female who presented with an unruptured right paraclinoid aneurysm. The 3D virtual model was then converted to a physical life-sized model.

Results: The model constructed was shown to be a very accurate depiction of the aneurysm and its associated vasculature. It was found to be useful, among other things, for surgical training and as a patient education tool.

Conclusion: With improving and more widespread printing options, these models have the potential to become an important part of research and training modalities.
