Endovascular interventions have become standard procedures for the therapy of abdominal aortic aneurysms. Therefore, endovascular surgeons need special skills which have to be learned and trained. Additionally, authentic simulators are needed for further development of new endovascular devices and procedures. The aim of this project was to develop an authentic and modular endovascular simulation environment with patient-specific vascular anatomy for training and research purposes.
We first designed a prototype with exchangeable 3D-printed patient-specific vascular anatomy. Then, the feasibility of the prototype was validated by a simulation of an EVAR procedure in a clinical setting.
We developed an authentic endovascular simulator with an exchangeable patient-specific vascular anatomy and performed an EVAR procedure under realistic conditions. The evaluation of the accuracy of the vascular models showed little deviation when compared with the original CT data.
Endovascular simulators based on patient-specific 3D-printed vascular models can realistically mimic endovascular procedures and have the potential to be used for further development of new devices and grafts as well as for training purposes. Furthermore, in our opinion they can reduce the use of animals during developmental processes.
血管内介入治疗已成为治疗腹主动脉瘤的标准方法。因此,血管内外科医生需要学习和训练特殊技能。此外,还需要真实的模拟器来进一步开发新的血管内设备和程序。本项目的目的是开发一种具有患者特定血管解剖结构的真实和模块化的血管内模拟环境,用于培训和研究目的。
我们首先设计了一个带有可交换 3D 打印患者特定血管解剖结构的原型。然后,通过在临床环境下模拟 EVAR 手术来验证原型的可行性。
我们开发了一种具有可交换患者特定血管解剖结构的真实血管内模拟器,并在真实条件下进行了 EVAR 手术。血管模型准确性的评估结果显示,与原始 CT 数据相比,偏差很小。
基于患者特定 3D 打印血管模型的血管内模拟器可以真实地模拟血管内手术,并且有可能用于新设备和移植物的进一步开发以及培训目的。此外,我们认为,它们可以减少在开发过程中对动物的使用。
