Abstract: Background: Endovascular aneurysm repair (EVAR) requires a high-level of technical-competency to avoid device-related complications. Virtual reality simulation-based training (SBT) may offer an alternative method of psychomotor skill acquisition; however, its role in EVAR training is undefined. This study aimed to: a) benchmark competency levels using EVAR SBT, and b) investigate the impact of supervised SBT on trainee performance. Methods: EVAR procedure-related metrics were benchmarked by six experienced consultants using a Simbionix Angiomentor EVAR simulator. Sixteen vascular surgical trainees performing a comparable EVAR before and after structured SBT (>4 teaching sessions) were assessed utilising a modified Likert-scale score. These were benchmarked for comparison against the standard set by the consultant body. Results: Median procedural-time for consultants was 43.5 min (IQR 7.5). A significant improvement in trainee procedural-time following SBT was observed (median procedural time 77 min [IQR 20.75] vs. 56 min [IQR: 7.00], p < .0001). The mean (SD) trainee Likert score pre- and post-SBT improved (16.6 [SD 1.455] vs. 28.63 [SD 2.986], p < .0001). Fewer endoleaks were observed (p = .0063) and trainees chose an appropriately sized device more often after SBT. Conclusion: This study suggests that EVAR-SBT should be considered as an adjunct to standard psychomotor skill teaching techniques for EVAR within the vascular surgery training curricula.
