Recent advancements in simulation permit patient-specific rehearsal of carotid artery stenting procedures. This study evaluates the feasibility of transferring patient-specific CT data into the simulator, creating a 3D reconstruction and performing a rehearsal. The face validity of the model was assessed.
METHODS/RESULTS: By thematic analysis of qualitative data, an algorithm was generated, focusing on simulation set-up, time of data transfer, software/compatibility issues and problem-solving strategies. The face validity of the simulated case was evaluated by 15 expert interventionalists: realism (median 4/5), training potential (median 4/5) and pre-procedure rehearsal potential for challenging CAS cases (median 4/5) were rated highly.
Setting up a procedure rehearsal is feasible and reproducible for different patients in different hospital settings without major software compatibility issues. The time to create a 3D reconstruction of patient-specific CT data is a major factor in the total time necessary to set up a rehearsal. The face validity is highly rated by experts.
最近模拟技术的进步使得颈动脉支架置入术的个体化预演成为可能。本研究旨在评估将个体化 CT 数据传输至模拟器、建立 3D 重建并进行预演的可行性，并对模型的表面真实性进行评估。
方法/结果：通过对定性数据的主题分析，生成了一个算法，重点关注模拟设置、数据传输时间、软件/兼容性问题以及解决策略。15 名介入专家对模拟病例的表面真实性进行了评估：病例的真实性（中位数 4/5）、培训潜力（中位数 4/5）以及复杂颈动脉支架置入术病例的术前预演潜力（中位数 4/5）均获得了高度评价。
在不同医院环境下，针对不同患者，设置个体化预演是可行且可重复的，且不存在主要的软件兼容性问题。建立个体化 CT 数据 3D 重建所需的时间是设置预演总时间的一个重要因素。专家对表面真实性评价较高。
