Integrating simulation into aneurysm treatment planning, experience and perspectives

Last update on July 8, 2026

Razvan Radu and Sandor Nardai discuss the transformative impact of simulation software on neurointerventional workflows. They highlight how implementing patient-specific predictive models addresses financial constraints and eliminates sizing errors for intrasaccular devices. From shortening the learning curves of large clinical teams to preventing complications in elective aneurysm cases, their insights prove that advanced simulation is an essential asset for modern operators.

Mitigating costs and perfecting sizing in resource-limited settings

Operating in resource-limited healthcare environments requires absolute technical precision. Sandor Nardai emphasizes that using simulation software is the only cost-effective way to adopt next-generation neurovascular implants when healthcare systems only reimburse a single device per procedure. Operators can no longer afford trial-and-error in the angio suite.

The practical financial and clinical utility of a dedicated simulation tool is further demonstrated by avoiding costly sizing mistakes:

  • Zero device waste: Razvan Radu shares that since incorporating simulation after his fellowship, he has never had to remove or replace an incorrectly sized intrasaccular device.
  • On-demand inventory planning: In centers without extensive consignment stocks, pre-diagnostic virtual simulation allows operators to accurately predict the exact implant dimensions needed, enabling them to request precisely fitted devices from distributors ahead of scheduled procedures.

Elevating team training and predicting complex coiling outcomes

Managing high-volume stroke centers requires training large teams of interventionalists. Integrating the Sim&Cure solution allows junior physicians to safely interact with complex vascular morphologies. By simulating ten different therapeutic strategies on a single patient's anatomy, fellows can flatten their learning curves, anticipate errors, and safely assist in live surgeries without compromising patient safety.

Furthermore, they agree that simulation software is not just for trainees; it is changing patient management for experienced operators. When performing preventive treatments on asymptomatic patients where zero complications are permissible (aiming for an mRS of 0), visualizing the procedure beforehand provides procedural calm and confidence.

Looking forward, the software's ability to predict recanalization rates and evaluate packing density could prevent critical coiling errors. It might guide the operator on whether to deliver that problematic "last coil" or stop the procedure safely, ensuring optimal occlusion without forcing a stretched or oversized coil into the aneurysm sac.
