Surgical Training for the Management of Intraoperative Aneurysm Rupture Using a Three-Dimensional Artificial Model.

Author information

Department of Neurosurgery, National Defense Medical College, Tokorozawa, Saitama, Japan.



Intraoperative aneurysm rupture (IAR) is one of the most dreaded complications of microsurgical cerebral aneurysm clipping. The surgical result is directly affected by whether an operator can control IAR. However, the development of endovascular treatment has decreased the probability of exposure to this situation for neurosurgical residents. Therefore, neurovascular surgeons must develop the skills and mental attitude to deal with IAR through off-the-job training, without conducting actual operations.

Materials and Methods:

We have developed a tabletop training system using three-dimensional artificial modeling that can be used for daily clinical practice.

Results and Conclusions:

Our model is useful for training because of its low cost, reusability, and ease of preparation and practice.
