Three-dimensional simulator: training for beginners in endovascular embolization with liquid agents

Abstract Background To design a simulator for novices without prior experience in embolization with liquid agents such as n-Butyl cyanoacrylate (n-BCA) and to evaluate the simulator using surveys and post hoc video analysis. Materials and methods The simulator was created using computer-aided design...

Materials and methods The simulator was created using computer-aided design software and three-dimensionally printed. Before an embolization, trainees completed questionnaires regarding their level of expertise and self-reported confidence level. The participants were shown an instruction video and each participant performed four embolizations on the simulator. Subsequently, the participants completed surveys on self-reported confidence level and assessed the simulator’s face and content validity. Results Five experts and twelve novices trained on the simulator. The experts were radiology residents and fellows with at least 5 years of work experience in interventional radiology. The novices were medical students and radiology residents without any previous experience with embolization. Based on the surveys, the experts assessed the simulator as very useful for embolization training. Performance, e.g. mean duration embolization between experts (mean ± standard deviation = 189 ± 42 s) and novices (mean ± standard deviation = 235 ± 66 s) were significantly different (p = .001). The overall simulation of the embolization process, simulated complications, and educational capabilities of the simulator were evaluated positively. In the novice group the self-reported confidence level significantly increased (p = .001). Conclusion The liquid embolization simulator proposed here is a suitable educational tool for training embolization procedures. It reduces the duration of embolization procedures and improves the confidence level of beginners in embolization.Michal MatyjasMarius SauerbreySebastian WyschkonMaximilian de BucourtMichael ScheelSpringerOpenarticleEmbolization, therapeuticSimulationTrainingRadiology, interventionalEndovascular proceduresDiseases of the circulatory (Cardiovascular) systemRC666-701ENCVIR Endovascular, Vol 4, Iss 1, Pp 1-9 (2021)
