A Method for Developing a Free-Standing Cerebrovascular Lumen Model.

Objective: This report describes the creation of a freestanding cerebrovascular model with an attached Luer valve device and a bridge.

Case presentation: A left internal carotid artery aneurysm was discovered during a detailed examination of headaches in a 70-year-old woman. A vascular lumen model was created for the pretreatment simulation. The addition of a male Luer valve and bridge to the vascular lumen model created using the multistep vascular wall thickness method facilitated lumen washing, support material removal, self-support, and compatibility with medical devices.

Conclusion: By adding Luer valves and struts and creating cerebral vascular lumen models with appropriate vessel wall thicknesses, we can enhance their efficiency, strength, and utility in preoperative simulations.
