Area of Science:

  • Medical Simulation
  • Endovascular Procedures
  • Neurointerventional Radiology

Background:

  • Simulators are increasingly utilized for endovascular procedure training.
  • The validity of the Mentice vascular interventional system trainer (VIST) simulator for neuroradiology requires empirical evidence.

Purpose of the Study:

  • To test the construct validity of the VIST simulator in neurointerventional radiology.
  • To differentiate between beginner and expert neurointerventionalists' performance on the simulator.
  • To evaluate the simulator's capacity to demonstrate a training effect.

Main Methods:

  • Four experts and six beginners performed diagnostic angiographies on the VIST simulator.
  • Performance metrics included total time, fluoroscopy time, contrast medium usage, and material changes.
  • Physiological data (gaze direction, heart rate) and workload were also recorded.

Main Results:

  • Significant differences were observed between beginners and experts in total duration, fluoroscopy time, and contrast agent volume (p < 0.05).
  • Beginners showed significant improvement in these metrics with repeated practice.
  • Familiarity with a case significantly reduced total and fluoroscopy time (p < 0.001).

Conclusions:

  • The VIST simulator demonstrates construct validity for diagnostic neuroangiography.
  • A significant training effect was observed in beginner neurointerventionalists using the simulator.
  • The VIST simulator is recommended for extensive use in the initial training of neurointerventionalists.
